Top 10 Worst Science Fiction Movies

Jamie Frater . . . Comments

So, we have looked at the best science fiction books and movies, but how about the worst? I have scoured the net looking for the worst of the worst, and after a lot of tough decision making, here it is! The ten worst science fiction films ever made – with youtube clips! Ordered from worst to worstest. [Yes, I know that is bad English.]

10. Star Trek: The Final Frontier, Director: William Shatner [1989]

I had to include at least one Star Trek film. It was a tough pick between this and Nemsis, but this one wins. The crew of the Federation starship Enterprise is called to Nimbus III, the Planet of Intergalactic Peace. They are to negotiate in a case of kidnapping only to find out that the kidnapper is a relative of Spock. This man is possessed by his life long search for the planet Shaka-Ri which is supposed to be the source of all life. Together they begin to search for this mysterious planet

You don’t need to settle for the worst Star Trek—buy the whole film collection! It’s the perfect gift for a Trek fan. Buy Star Trek: Original Motion Picture Collection at!

9. Superman IV: The Quest for Peace, Director: Sidney Furie [1987]

The clip is short – but you get the point – falling in space? What happened to gravity? Lex Luthor steals a hair of Superman’s head from a museum and uses it to create Nuclear Man, an android that gets energy from the Sun. His purpose of course is to use him as a weapon to kill Superman, so that Luthor will be free to realize his criminal plans.

8. Frankenstein Conquers the World, Director: Ishirô Honda [1965]

During WWII, a human heart taken from a certain lab in Europe (Dr. Frankenstein’s) is kept in a Japanese lab, when it gets exposed to the radiation of the bombing of Hiroshima. The heart grows in size, mutates and sprouts appendages, and eventually grows into a complete body and escapes. Later, a feral boy with a certain physical deformity (a large head with a flat top) is captured by scientists who refer to the boy as Frankenstein. The creature grows to the height of 20 feet, escapes again, fights police and army, and is practically indestructible. Later, a reptilian monster goes on a rampage. Eventually the Frankenstein creature and the reptile face off in a terrible battle.

7. Robot Monster, Director: Phil Tucker [1953]

Watching this clip, I think I understand why women were not in the military in 1953! The Robot Monster has been sent to Earth as the advance party of an impending invasion. Ordered by The Great One to capture several humans, the Robot Monster becomes confused once it learns more about humans.

6. Sant Claus Conquers the Martians, Director: Nicholas Webster [1964]

My favorite line: Martian1: “You stay away from those children!” Martian 2: “That will be easy to do. They’ve escaped!”. Martians, upset that their children have become obsessed with TV shows from Earth which extoll the virtues of Santa Claus, start an expedition to Earth to kidnap the one and only Santa. While on Earth, they kidnap two lively children that lead the group of Martians to the North Pole and Santa. The Martians then take Santa and the two children back to Mars with them.

5. Monster a go-go, Director: Bill Rebane [1965]

“When you walk out, you will wonder what you have seen!” – I think the voice-over guy was having a premonition! An astronaut comes back to Earth and crashes in a field, incredibly irradiated and wreaking havoc. Just as they have him cornered, he disappears, and the “real” astronaut is found 7,500 miles away in the Pacific Ocean, “alive, well, and of normal size.”

4. Turks in Space (Dünyay? Kurtaran Adam in Oglu), Director: Kartal Tibet [2006]

Hmm – where have I seen those light-sabers before? This one is so bad that I can’t even find a synopsis for it! I will just say, this is rated the 6th worst film by IMDB (including non-SF films).

3. Plan 9 from Outer Space, Director: Edward D Wood Jr [1959]

“Can your heart stand the shocking facts about Graverobbers from Outer Space?” That’s the question on the lips of the narrator of this tale about flying saucers, zombies and cardboard tombstones. A pair of aliens, angered by the “stupid minds” of planet Earth, set up shop in a California cemetery. Their plan: to animate an army of the dead to march on the capitals of the world. (The fact that they have only managed to resurrect three zombies to date has not discouraged them.)

2. The Beast of Yucca Flats, Director: Coleman Francis [1961]

A defecting Russian scientist is transformed by an atomic test into a hulking monster, Tor Johnson, of course. Not much else except some people are killed, boys get lost, and a rabbit sniffs Tor’s corpse. If you liked the clip, watch the whole thing here.

1. Battlefield Earth, Director: Roger Christian [2000]

How could this have not been a disaster? It is effectively a Scientology advert in film format. Someone put together a nice little clip of the best/worst bits so I have used that here. In the year 3000, man is no match for the Psychlo’s, a greedy, manipulative race of aliens on a quest for ultimate profit. Led by the seductive and powerful Terl (Travolta), the Psychlo’s are stripping Earth clean of its natural resources, using the broken remnants of humanity as slaves. What is left of the human race has descended into a near primitive state, believing the invaders to be demons and technology to be evil.

    Ooooooohhh, Battlefield Earth as the worst Science Fiction movie! I bow to your superior Kung Fu. I had erased that film from my mind.
    But now it's back. Damn…

    Santa Claus Conquers the Martians. An exquisitely horrible movie, which starred that 80's alleged sexpot, Pia Zadora as one of the chidren.
    I think it's safe to assume her career peaked with this film.

    Robot Monster. Sadly, I have never made it through the whole movie. Usually, after the first ten or fifteen minutes, I'll begin to feel a bit… urpy, then my entire lymphatic system will be filled with deep ennui, at which point, I will feel the overwhelming urge to massage my skull with a ballpeen hammer.
    Ultimately, I will need to be resuscitated by the Swedish Bikini Team.
    Thank God for bad movies.

    Star Trek: The Final Frontier. Another movie I've not had the misfortune to watch all the way through, as my wife always turns off the TV when it gets to the scene where Shatner falls off the mountain and Spock dives to save him and I begin shouting, "DON'T DO IT, SPOCK! DO US ALL A FAVOR AND LET HIM FALL! SPOOOOOOOOOCK!!!"

    (Oh, and apropos to nuthin', why was there no mention of that excellent 60's film, Bambi Meets Godzilla" in the best movies thread? See for yourself!

    • Ngobleus

      You’re not missing much with Star Trek V. It would have been a lot better if Paramount hadn’t insisted on a lighthearted treatment, and hadn’t cut the budget down, forcing cheap special effects–about half of which didn’t make the final cut and resulting in a quick and lousy ending. It would have been awesome if those parts of the chase scene at the end hadn’t had to be removed–Shatner’s original intent was to make the fake “God” they find at the end of the film to really be more like the Devil, even with a representation of the 10 circles of Hell.

      Instead we got a floating head that’s weak against Klingon firepower (and probably doesn’t like having torpedoes shot at it either).

      On the plus side, the film makes heavy use of the Kirk-Spock-McCoy power trio and Laurence Luckinbill gives what I consider to be a good performance as Spock’s brother.

  • RobS: haha – Bambi and Godzilla – who comes up with this stuff?

  • Actually pretty cool movies :

    I loved the special effects on Frankenstein and Baragon – awesome.

    The robot monster had me riveted to the screen, I must see the rest

    How did they make those martian guys look so real ? Bit brutal this flick, lots of swearing and violence.

    Digged the pretty girls on Monster a Go Go – it rocked and socked me.

    The love scene in Yucca Flats was a bit uneccesary

    Good list well done…

  • Andre: Thanks :) I am amazed you have seen so many of them all the way through :)

  • Joe

    No Jar Jar binks movies made the list?

  • Joe: tempting – but I think the others were worse :)

  • Good list, not supprisingly, i’ve only seen a few of these movies.
    As for the Star Trek pick, good choice, but i think Nemisis, or Star Trek I would have been a better choice.

    Battlefield earth, i agree, wow, that was one other movie.

    The thing that supprised me was 1998’s Americanized version of Godzilla IMDb
    that wasn’t very good, at all. And the best part of it was that they set it up for a major sequel, that never happened…

  • steve: It was a toss up between nemesis and final frontier. I don’t think I have seen the American Godzilla – and based on your comments, I don’t think I will :)

  • Rishtardo

    How dare you rate “Star Trek: The Final Frontier” as one of your 10 worst! I think that it’s the best “Star Trek” movie of them all!

  • Rishtardo: are you from earth? :)

  • dalandzadgad

    this is great, i needed a good laugh. “Battlefield Earth” was the best (or worst).

  • As a Trekker, I stand by JFs number 10. Not just because of the bad acting, but because of the science within it. The “Galactic Core”, You mean the Blackhole From which there is no escape. It Sucks, if you can’t see that with your own eyes, ask the cast. They thought they had ended their careers with that movie. And Bravo for pointing out why I have yet to see “Battlefield Earth.”

  • Beeyotch

    What’s worrying is that I have seen ’em all, bar one…I so had no social life growing…

  • RobS

    Beeyotch (May I call you that?),
    I feel your pain.
    I’ve spent so much of my time through my life watching perfectly horrible sci/fi movies, possibly due to the belief, “That which does not kill you, makes you cranky”.
    Or maybe just because I’ve always found them hilarious.
    Probably why I was drawn to MST3K.

    Another good one is, “Teenagers From Space”, which boasts a cast of tired, jaded, 30-something year old “teenagers” and a giant lobster thermidor, called a “Gargon”.
    A truly memorable flick.

  • Beeyotch: in a horrifying way that is impressive!

    RobS: Thanks for the mention of Teenagers from Space – I will be sure to keep my eyes peeled for that… or not!

  • Daniel

    what about Howard the Duck!!!?

  • Daniel: I haven’t seen that – synopsis?

  • James Smith

    For me, the worst film of all time, not just Sci-Fi, was “Nightfall” based on the classic Isaac Asimov story. Because Asimov’s work was so good, I thought the film would be at least passable. Wrong!!!

    The film, starring David Birney, was so bad instead of walking out, I stayed. I kept thinking it HAS to get better! Wrong again, it only got worse.

    To be fair, I have not seen all the films on your list, but Nightfall could surely replace several of them, it was so bad.

  • James: that would bother me a lot as I love Asimov’s books. I didn’t mind I Robot too much but it did have a bit of a b-grade feel I thought.

  • RobS



    Quickly, drop whatever it is you’re doing this very instant and hie thee hence to your nearest video store.
    Now, before you actually watch the movie, you will need to…erm… prepare yourself.
    Remember the scene in Clockwork Orange, where Alex is being forced to watch videos while undergoing the “Ludivigo Treatment”?
    OK, you’ll need to have someone strap you down, clamp your eyes open with those really gross eye clamps, and drop saline solution into them so they won’t dry out.
    The effects of actually watching Howard the Duck will be surprisingly similar to Alex’s after undergoing the treatment, but don’t worry… you too will heal.
    I’ve seen the movie and look how normal I am.


  • RobS: haha – I don’t know if that is high praise or utter horror! I will be sure to add it to my amazon wishlist…. :)

  • Chris

    Where the hell was “The Phantom Menance”??! That’s GOTTA be on the list!!!

  • Chris: it was sooo close!

  • heather

    starship invaders. one of the very few films that i have ever, ever, walked out of before experiencing the excruciating ending. (i later saw it again nd it was all still terrible.) no lie, it would top this list. plan 9 is a classic, despite its horribleness.

  • heather: I haven’t seen it – I will add it to my list of must-sees :)

  • Alli

    Thank you thank you thank you! I have been trying to remember the name of a movie I loved as a kid; and there it is, on your list. Frankenstein Conquers the World *happy sigh* I’m going to have to add that to my Amazon wishlist.

  • RobS


    ARE YOU MAD?!?!?!

    They were using that movie as a torture device at Gitmo, until the U.N. Commission said, “Roight! Knock that off right now and we’ll give you a wave on the water boarding!”

    Actually… that was all a lie.

    But, I have to admit, watching movies like “Frankenstein Conquers the World”* is a harmless bit of fun, isn’t it?

    Unless people find out, that is.

    And I’ll be keeping my eye on you from now on…

    *He doesn’t actually conquer much of anything, though, does he? Sad, really…

  • Alli

    *grins* I am insane, but that’s another story.

    As for Frankenstein Conquers, it was one of many monster/sci fi flicks we watched with my dad Sunday afternoons in the late 70s. Godzilla, Rodan, Gamera, we watched em all. This was the only one I could not remember and I can finally put it to bed (after I locate it, call dad and we watch it again).

  • Alli: I am very pleased that this list of awful movies has helped you so much :)

  • RobS


    Those terrible Japanese rubber-suited monster flicks are… quite special aren’t they?
    I can recall staying up late on Friday nights with some of my buddies, watching Godzilla first be a bad guy and then be a good guy…
    Remember the one where Godzilla meets Mothra and there were those two tiny Japanese girls in the ornate box?
    Those kinds of images can do wierd things to 12 year old boys.

  • Che

    *an experiment gone horribly wrong
    *loads of car crashes
    *Ray Milland (the Oscar winner)
    *a socially responsible message

    Ladies and gentlemen, I give you…

    The Thing with Two Heads!

    • josh

      is that movie real? it seemed more like a saturday night live sketch than a real movie.. especially the line “Maybe, i will donate my body to science, after all.” LOL

  • RobS: hah you describe that so well :)

    Che – thanks for the worthy addition :)

  • bluebandit

    no way does battlefeild earth belong on this list. that was an awesome movie. you wanna talk about the worst sci fi movie ever, watch the new hitchhikers guide to the galaxy movie. you’ll stab your own eyes out before the end

  • bluebandit: I haven’t seen that one yet – I will try to see it soon so I can post an informed opinion.

  • RobS

    It’s too bad about Hitchiker’s Guide, because the book is just so gosh-darned funny.
    But, some things just don’t translate well to the screen.

    And as for Ray Milland… wasn’t he also in “The Night of the Lepus”, where humanity is in danger of being eaten by giant rabbits? Or was he in the one with the giant frogs? Well, be that as it may, I remember watching the “Thing With Two Heads”, thinking, “The Lost Weekend” was a long, long time ago, wasn’t it Ray?”

  • AvaAdore

    Ghost of Mars


  • Rob: I haven’t seen that – I will see if I can find it.

    AvaAdore: I haven’t seen that either – consider it included in my to-watch list.

  • RobS


    You like to torture yourself, don’t you? :^)


  • RobS: I owe it to the users here :)

  • watson

    my little brother allways did describe Battlefield Earth as “Star Wars meets the smell of Ass”

    A very good(bad)list overall

  • watson: hah thanks for sharing :)

  • jack

    I have to say that the worst s/f movie of all time is ‘The Day After Tomorrow’.

    They were chased by >cold

  • Randy

    I would have to agree with bluebandit. Now, Battlefield earth was horrible. I remember seeing that on my friend’s birthday, and I really wanted to see Rules of Engagement. But alas, my friend wanted to see Battlefield Earth. Terrible movie, the bad thing is, is that he actually bought it when it came out on DVD. I do believe, however, that The Hitchhikers Guide to the Galaxy was a terrible movie. What other movie do you have that the world is financially backed by mice and the smartest creatures are dolphins that talk to aliens? I tried to make sense of the movie, but just couldn’t. The robot is the only reason why I wanted to see this movie, being a depressed, sad sap robot. But no, even he could not make up for a laugh in that movie. Battlefield Earth was a horrible movie, but The Hitchhikers Guide to the Galaxy was far worse. It was possibly the worse film put on 90 minutes of tape in the history of man. Period.

  • Randy: thanks for that truly impassioned perspective :)

  • Randy

    Your welcome jfrater….but I can say it was probably worse than Spice World…another film that I was dragged to go see….uggghhh…women…lol

  • Randy: I am incredibly pleased to say I have not seen Spiceworld!

  • Randy

    unfortunatly i’m not :( what about that movie that had tim allen in it. sort of like a star trek spoof. that was pretty awful. damn, now if i can only remember the name. arrggg

  • Randy: oh – I remember that film too – I don’t think I watched it but I did see a trailer.

  • brlove

    You missed Mission to Mars… arguably the worst movie ever sf or otherwise

  • briove: thanks for the addition – maybe we will have to do another few top 10s!

  • Randy

    I do also remember a movie from when I was six, I think, about a gigantic boob coming down and attacking a city. Quite facinating, and probably a good one to put on the list. I don’t think that it would have been ever nominated for any academy awards….well, unless there is a catagory for the-biggest-breast-in-a-movie award.
    Ahhhh, memories.

  • Randy – how hilarious and how bizarre!

  • Randy

    hey, i try

  • Randy :)

  • Cyph0n

    I can’t believe you didn’t mention The Adventures of Pluto Nash. And I have to admit, I LOVED Howard The Duck.

  • Aaron

    First of all, sorry for the harsh language, but you’re missing one of the worst sci-fi, nay, the worst MOVIES of all time: “Gay N*ggers from Outer Space”.

  • Matt

    I think either Star Wars Episode I or II could easily make the list. I think one could also make the case that Star Trek I was worse than V. Mars Attacks could be on there as well.

  • Cyph0n: I haven’t seen Pluto Nash – when did it come out?

    Aaron: Unbelievably Gayniggers From Out of Space seems to have quite a following on IMDB!

    Matt: I did consider Mars Attacks – thanks for mentioning it :)

  • I guess SuperMan IV wasnt part of orginal movie series, right? ’cause i cant remember it. By the way, “falling space” ? Well Earth still could pull it. But what about being able to survive in space!! Is that girl a android?

    And “Dünyay? Kurtaran Adam’in Oglu” is an absurd comedy. I actully laughed in 1st half. But yeah, it’s a bad movie…

  • Özhan: I am not sure if it was done by the same people but Christopher Reeve is playing Superman.

  • Che

    Just watched GayN-Words from Outer-Space.
    It truly is awful – in an unfunny way. Maybe it’s funnier in Danish. As satire goes, this is pretty lame. Tries hard to offend just about everybody – and fails miserably.

    But if y’all really want to waste 30 minutes of your life, like I did, here’s the YouTube link. Complete with gratuitous Carlsberg advert.

    Thanks, though, Aaron.
    You owe me thirty minutes. ;+)

  • RobS


    The Tim Allen movie you’re thinking of is “Galaxy Quest”, which I thought was a fairly funny movie. But, as in all things, your milage may vary.
    The giant boob you mentioned reminds me of a scene from Woody Allen’s “Everything You Ever Wanted To Know About Sex”. You might be remembering that.


  • Che hah I can’t believe you found a copy to watch! Thanks for the link :)

  • Che

    No reason you have to do all the hard work Jamie.


  • Che: Thanks :)

  • Klaatu

    Amazing list. Quite inspired. :-)

    One thing about “Battlefield: Earth” is not just how bad the movie was, but how incredibly wrong they got the book.
    The movie story is so lame, there are so many aspects of the book that just didn’t make it to the screen… I felt violated. :-)
    It’s like releasing “Tremmors” with the title “Dune” (not that Tremors was bad, I loved it, actually).

    There you go. My mood is ruined for the day.

  • Pulsarav

    My favorite “worst” Sci-Fi flick I can remember in my 50 years is Laserblast:

    Too many “bad” things to list but here are a couple of examples:

    Beams from the aliens’ ray guns are purple with green lightning bolts in the center of the ray.

    In Roddy McDowall’s scene the microphone is in view. They even spelled his name wrong in the credits (Roddy McDowell).

    It’s available on Netflix, so if you want to torture yourself (or have a great laugh) check it out.

    • Kees de Koster

      MST3K did Laser Blast. Just beautiful. It’s on their 20th anniversary DVD. I missed half the the jokes cos I was laughing so very hard.

  • JJ

    battlefeild earth should have stayed on the page say what you want about Hubbard this was a good book the movie on the other hand was so bad i walked out half way through and demanded my money back

  • Punjar

    Battlefield Earth definitely belongs at number 1. The book was just way too long to make into a good movie. I don’t know how anyone who didn’t read it followed the plot at all. I vaguely remember it jumping all over the place. (It’s been a while since I’ve seen it.)

    Also, there’s a really funny episode of Mystery Science Theater: 3000 where they show Santa Claus Conquers the Martians. I’d recommend watching it.

  • specter

    Evidently, nobody’s seen “Space Mutiny”. Just awful, all the space shots to include the ship is reused footage from the original Battlestar Galactica. And let’s not forget brick walls on a space ship.

  • stephen

    you have forgotten to include Star wars 1,2,3,4,5 and 6

  • specter: haha – I loved the original battlestar gallactica! I wanted to be starbuck – he was so cool.

    Stephen: I didn’t forget – they are number 11, 12, 13, 14, 15, and 16 :)

  • Punjar

    I don’t know if it’s one of the 10 worst, but Logan’s Run was pretty stupid at times.

  • Pingback: Movies » Comment on Top 10 Worst Science Fiction Movies by Punjar()

  • aplspud

    I think some band did a song using sound clips from “Santa Claus Conquers the Martians” but I may be wrong. Anyone know it?

  • Punjar: I remember Logans run – it was bad.

    aplspud: I am not familiar with it but I would be very curious to hear it. Let us know if you find out what it is.

  • Pingback: depotqz » Blog Archive » Comment on Top 10 Worst Science Fiction Movies by aplspud()

  • IMSA12

    I nominate “The Creeping Terror”, an early 60s B&W flic that was so profoundly bad that, even though I viewed it only once, I still remember it fondly 25+ years later. The title creature resembled a shag carpet/compost heap whose mode of attack was to engulf its victims, although I recall that some of its intended prey had to literally push themselves into its maw (which resembled a “doggy door”). One poor fellow tried to escape this fate by beating the creature with an acoustic guitar, but alas, he and his girlfriend are thusly consumed. This movie was wonderfully awful in every possible way. Unfortunately this terrible treasure has been lost; at least I can’t find it anywhere!

  • aplspud

    Ok, so after hours of searching (instead of writing a paper of course) I’ve figured out the name of the band is The Laziest Men on Mars (of All Your Base fame). There are actually several songs that feature clips from Santa Clause Conquers the Martians. “Nothing Can Stop Torg!” can be found on YouTube, though that’s not the one I was originally thinking of. A write up on the group with a list of their songs can be found at If anyone can find MP3s of the songs, I would be sooo happy!

  • Ogre

    I think you kinda cheated here, I mean come on, let’s stick to SERIOUS sci fi, or at least, Sci Fi that takes itself seriously. I wouldn’t include Santa Claus Conquers the Martians or Monster a Go Go in this list, and Plan 9 has always been considered camp theatre. There’s plenty of really bad Sci Fi out there to go around… Every Aliens after II, Solaris, Lost in Space and the Hellraiser in space movie are all good candidates.

  • ChuChu353

    “The Beast of Yucca Flats” is completely, utterly, thoroughly unwatchable without the MST3K commentary.

  • ChuChu353

    And while we’re on ghastly sci-fi film, here is part of a commentary I recently left on another website concerning that classic “The Incredible Two-Headed Transplant”

    “…the great MST3K episode that never was. As romantic leads, you had Casey Kasem and Pat Priest. Kasem’s experience as the voice of Shaggy on Scooby Doo no doubt sealed his cartoonish creature credentials, while Priest, of course, had tons of experience sharing screen time with big, lumbering stupid monsters. As for the two-headed transplant of the title, that was none other than future Academy Award nominee Bruce “what the hell am I doing in this film” Dern.”

  • ChuChu353

    Sorry, Dern played the scientist, not the monster. My bad :o

  • Peggy

    I liked Battlefield Earth,but the rest,no.Some ive never heard of.
    How do you find time for this??

  • Peggy: I seriously don’t know :)

  • Dangerous Dan

    Two films far worse than the worst Star Trek ever offered: 1) Disney’s “The Black Hole” which was the only movie I ever wanted to walk out on. This movie contained two appallingly annoying hyper-cute robots, no science content to its fiction, and, the violent scene where a robot cuts a man’s heart out with a spinning blade spills not a drop of blood. The movie has no redeeming features that I can recall.
    2)Wing Commander, a retooled WWII ships-and-submarines movie in which, at one point, a crashed fighter is bulldozed off of the carrier’s landing deck and it falls. Both of these movies hammered my bullshit button until the circuit breaker blew.

    Also, if you ever get a chance to see the obscure film “Yor, Hunter from the Future”, AKA Mondo di Yor, Il, you’ll want to find a place for it on this list.

    BTW, I have to agree that Plan 9 and The Beast of Yucca Flats are more enjoyable less painful than Battlefield.

  • eye_snap

    well, dünyay? kurtaran adam?n o?lu is the sequel to the movie ‘dünyay? kurtaran adam’ and it is very famous in turkey with the effects being so funny and such. the real funny thing about it is in fact that; in 80’s, when asked cüneyt ark?n (the lead actor) used to say stuff like ‘we didnt have enough money but i think the effort still counts, you dont have the right to laugh at it! we worked our asses off, people!’ but when nobody took him seriously and when the movie ‘dünyay? kurtaran adam?n o?lu’ was shot just for the laughs, he started giving interviews like ‘oh sure we deliberatly made it so funny. so we re doing a sequel now.’ cüneyt ark?n is a really wierd person. i am a cinema student in istanbul and i want to finish saying this: we were made to watch and study this movie as the worst turkish film ever made..

  • Harsha

    Nah!! I always felt Santa conquers the martians worse than Battlefield Earth…….How they made a movie wid that title I’ll never know!….Thanx for letting me know about the existance of “Bambi meets godzilla”….Ugh!

  • plan 9 from outer space is concidered by most movie reviewers as the worst movie ever si-fi or otherwise.

    “space truckers”…Dennis Hopper why did you do it to uswe love you so.

    and let it not be forgotten “attack of the killer tomatoes” its just so …so …so…there’s no saying just how bad it is.

  • Alexandra

    I haven’t seen any of these movies, and have never shown the least bit of interest in them – thank goodness.

  • D

    OK, if you can include Superman, then I feel free to nominate Roger Korman’s version of “The Fantastic Four” – so bad it didn’t even make it out of the studio! (A friend has a bootleg copy)

    I would also like to recommend “Oblivion” – a really cheezy wild-west-on-some-other-planet-we’ve-colonized movie. Cliches from two genres, it doesn’t get much better than this! George Takai as the town doctor (and drunk!) saying things like ‘I’m a doctor, not a mechanic!’ and Julie Newmar as Miss Kitty, the owner of the town’s saloon (and brothel), with the line “Sherrrrrriff! How perrrfectly wonderful to see you again!” Androids, empaths, reptilian aliens, a creepy undertaker, a “native” that looks like a really bad version of Tonto, evil female henchman (henchwoman?) wearing skintight patent leather and a whip…….and if this movie wasn’t enough for you, there’s a sequal, “Backlash” that’s just as bad as the first….

    Great things to watch on a rainy Satuday afternoon.

  • eric n.Er

    how about “attack of the killer tomatoes”!?!?

    love adding things bro… :)

  • Mike

    damn, they really overused angled shots.

  • copperdragon

    I agree with adding Pluto Nash.
    The Core (or whatever, with Hilary Swank) was pretty bad.

    Mars Attacks was hilarious!
    I need to go watch it right NOW!

  • Mystern

    hm. Turks in Space actually looks interesting. I might have to rot my brain watching it. Battlefield looks like a good comedy flick. And I loved the new Hitch Hikers Guide to the Galaxy. It’s about as close to Terry Pratchett as you can get on film . . .

  • The plot is Turkish space patroling ship intercepted by pirates. And a crew member kidnapped. In the quest of rescuing her, they discover a planet with civilization. And it turns out a Turk MIA astronaut is also there and leading an uprising against tyranny. And furthermore they also finds frozen body of “The man who saved Earth”. The movie’s 2nd half all takes on planet and filmed as a historical movie. So you dont need to buy 2nd CD :)

  • luckyaz

    hey, if santa claus can conquer the martians, why cant we conquer al quaida?

  • Drogo

    If the “Creeping Terror” that IMSA12(#76) is the movie I think it is, it ranks close to “Plan 9…” It had little, or no dialogue. A guy described what had happened in a Voice-over for the whole movie. The only dialogue I remember is girls screaming when they lose a shoe, fall down, then get eaten by what looked like 5 guys draped in a giant shag rug, holding it over their heads with broomsticks. There’s a scene where teenagers go to a “hootenanny.” I thought, “What the heck is a hootenanny?”

  • Cathal Brugha

    Ray Milland in Frogs. A wretched piece of film. As Leonard Pinth Garmell would say “Bad Cinema”.

    But I’ll watch it anytime it’s on


    battlefield earth winns haha
    i guess john travolta lost a good few million he was intending to make

  • mc

    There’s this movie called 2889, it’s worse than all these movies combined. It’s about telepathic zombie cannibals. I know it sounds awesome, but it isn’t.

  • Wagers

    Worst SF movie of all time: Star Wars.

    So now you think I’m a nut, a crank, a fool. Give me a chance.

    Get the picture: It’s the late 70s. Critics are finally beginning to recognize the serious contributions of Clarke, Heinlein, Herbert, Dick, Le Guin, Farmer, Sturgeon, Blish, and others. Then, along comes this innocuous, juvenile action flick called Star Wars. All of a sudden Star Wars is SF’s brand. All of a sudden, SF is totally irrelevant, a modern-day cowboy and Indian romp.

    So far it’s been 30 years; it will be at least another 20 before SF recovers from Star Wars.

  • God

    Wow, Its hard to imagine that any true science fiction buff worth their salt cannot believe that “NIGHTFALL”, the low budget 1988 Asimov rip-off by Double Day book club is not the worst movie of all time regardless if its science fiction or not. If there is still copies not burned I suggest if you can stomach at least to the hilarious, idiotic, and rather unpleasant sex scene you may become scarred for life!!

    Im sorry but whoever compiled this list mustve looked at a few other lists and made assumptions, because they sure the hell didnt see this flick!

  • beth

    What about Hell Comes to Frogtown? It has Roddy Piper in it.

  • stilgy

    There must be something wrong with me but I liked Battlefield Earth. The “Fantastic Four” & “The Adventures of Pluto Nash” were much worse than Battlefield was.

  • texasbob

    I can not believe you left out “Lepus” Giant rabbits attack!! It looks like they got all the rabbits they could find and dumped them on the set.

  • johnnyugly

    I haven’t seen any of these but aren’t most cult classics?

  • Ron

    Actually, I have a warm spot in my heart for most really bad sci fi. Movies like Plan 9 From Outer Space seems to be one of those that was meant to be bad. Star Trek: The Final Frontier was a big disappointment for me. I’m a huge Trek fan but this one is one of those sci fi movies that was supposed to be good…not like Plan 9…

  • Truthseeker013

    It occurs to me that, if one who had been condemned to Hell were to carry copies of these movies along, threatening to air them non-stop, that person could secure their release…

  • Adam

    One you’re missing form this impressive list is my own nominee for the worst movie ever — The Alpha Incident. Alien virus gets loose in small town while being transported cross-country by train! There are NO symptoms until you fall asleep and then . . . your brain goes bubbling out your ears! AWFUL!

  • Kogelo

    What about MARS ATTACKS! That was horrible

  • Kogelo

    Mars Attacks was one of the worst


    I like this list because I love watching SciFi, especially the really crappy “B” movies. However there are hundreds if not thousands of these movies that are just as bad or worse. Star Crystal, Death Machine or RobotJox to name a few. (How many of you have actually heard of these titles?) I think this list should be limited to the the big budget productions by the mega-companies of the U.S. So with that in mind, I agree that Star Trek 5, Superman 4 & Battlefield Earth should be on the list and I think the following movies also deserve consideration:
    The 6th Day
    Alien 3 & 4
    The Core
    Highlander 2 (actually all Highlander sequels)
    Terminator 3
    Red Planet
    Ghosts of Mars
    Judge Dredd
    Robocop 3

  • twitter

    Hello idiots what about FORBIDDEN ZONE!!!!!!!!

  • excel99

    Can we include TV? The Starlost is a must see for any B-crap masochists.
    “The giant Earthship ARK, drifting through space for 800 years, headed for destruction, unless three young people can save the Starlost.”
    Truly bad! The saddest part is that it was such a good idea, created by Harlan Ellison, of all people! Keir Dullea (of 2001 ASO fame) stars, and many episodes have some ‘name’ actors. Yet it still SUCKS! The first episode is actually intriguing, despite the poor production value. But once you’re hooked you have no idea the mind-numbing horror that awaits you! Truly evil! Most of the episodes are up on YouTube, if you dare!

  • bdogg

    What about wing commander with freddie prinze jr. ?

  • OhioRic

    I love ST – The Final Frontier for its pure cheese :)

  • Alex

    What about, “The Navy vs. the Night Monsters” or “Creature From the Haunted Sea” or “The Monolith Monsters” and who could possibly forget “Plan Ten from Outer Space?” There are so many wild and wonderful sci-fi films that can be brought up. By the way, to me “Nemesis” wasn’t as bad as “Insurrection.” All through the film I was waiting for an insurrection and it never came. I think the best part of the 1988 Godzilla film was when Godzilla was stunned leaning against a building, was hit by lightning and got jump-started. :-)

  • Lumpy da Moose

    During the Christmas holidays I got taken to see Santa Claus Conquers the Martians while my mother did some shopping. It was a turd even the when I was probably 13 or so. Gaahh!

    I actually found an AVI file of this on the Internet Movie Archive and played it for my kid who just didn’t believe his dad. You know– share the joy! It was great for a laugh!

  • Pete

    I liked The Final Frontier and Battlefield Earth. They attempted grand ideas before CGI became affordable. Lay off Shats and Hubs. (PS I’m not a Trekkie or an ‘Oligist)

  • Ken

    I love these movies! Robot Monster is the ultimate in 50’s kitsch and Monster a Go Go represents the 60’s. And there are so many more. This list should really be limited to serious films, not ones that were tongue in cheek. I know Ed Wood as a “serious” film maker, but really!

    And Mars Attacks was hilarious!

  • Ravana

    I can only assume that no one here ever saw “Moontrap” (1989), or else it would have been mentioned long ago–and repeatedly. The leading role is played by, of all people, Walter Koenig… a man cut out for supporting roles if ever there was one. You know how some movies (“Plan 9”) are so bad they’re good? This one goes well past that and plunges headlong back into “so bad they’re bad” again… and keeps on going.

    Not sure if “Lifeforce” (1985) belongs on the list or not, but it’s certainly worthy of consideration.

    A favorite of mine, not necessarily belonging on this list but one whose very concept merits being included on “worst story ideas of all time,” is “Sundown” (1991). It is–get this–a vampire western. I kid you not. (Actually, it’s worth watching just for the ending… which is quite novel for the genre. Not sure how it made it into this movie….)

  • Tip

    “The Killer Shrews” should be nominated. Dogs wearing rabbit-skinned coats!!!

  • BridgeTroll

    I own Santa Claus Conquers the Martians! Best. Fight choreography. EVER.

  • Seyma

    LMAO @ the turks in space. As a young lady of turkish descent, i never watched this movie knowing that it is one of the worst movies in turkish history. lol! However i think it was supposed to be a comedy movie and this movie has some background.

  • DAC

    Teenagers From Outer Space
    The Creeping Terror
    The Bride And The Monster
    Night Of The Gouls

    The last 2 are Ed Wood masterpieces.

    I agree on #1!! What a joke that was.

    ST Final Frontier was a victim of the writer’s strike and people that had feelings for the writer’s. I’m a fan, and it’s not one of my fav’s, but it was a shame that movie had to suffer

  • CanadianGirl

    You’re gonna kill me for sayin’ this, but I think that if any movie puts Q in a major role, I am going to kill the director.

    Any other Star Trek movie, I’m dying to find.

  • Sneeze

    i agree to the person who said Star Wars is shit. And im glad you didnt include Nemesis, it’s my favourite ST film besides first contact and the 2009 concoction. i also agree to the person talking about moontrap, featuring some original st actors. still, will someone explain to me why nemesis was supposed to be so bad?! i loved it.

  • jo

    Hmmm. The list is pretty cool. Has anyone seen dragon wars? Is that crap supposed to be sci fi? If it is then it belongs here. Yea I liked battlefield earth too. Lol. I’m surprised so many ppl hate it but to each his own.

  • Audrey

    Sure, everybody knows Martians have mustaches.

  • mtnmedic

    Oh my GAWD…have you guys missed it by a MILE. You’re all WAYYY off!

    The WORST sci-fi movie EVER was the horrid “Starship: Adventure of a Million Lifetimes”, which aired in 1984. My girlfriend and I had to suffer through that endlessly dark, weak and confusing dirge for almost 2 hours at a drive-through. We would have left the drive-in theatre halfway through the movie if it weren’t for the second feature, “DUNE”, which is why we went there in the first place.

    The ONLY good thing to come out of this stinker film at the drive-in was the quality time I got to spend with my girlfriend that DIDN’T involve watching the movie. :-)

    I’m telling you, “Starship: Adventure of a Million Lifetimes” is SOOOO bad, you can’t even FIND it mentioned anywhere on the web. Not in IMDB, not in the B- or C- films databases, nowhere. I once found it on a foreign ebay site for sale as a VHS tape but the guy wanted $12 plus shipping for the stinker. I offered $4 including shipping because even THAT’S more than what it’s worth. I just wanted to see it again so I could have a moment of nostalgia, laugh at it, then upchuck and lose some weight.

  • Mssy

    I liked Battlefield Earth. Is it so hard to believe that the first thing aliens would do would be to take over earth for their own gains? Hawkings seems to think it’s a pretty strong possibility…

  • nicoleredz3

    This entire list, is like, DUUUHHH!!! So true! But I didn’t think something could be worse than Plan 9, beside Battlefield Earth, ofcourse. Gotta make some time to see The Beast of Yucca Flats…

  • none

    Transmorphers: Fall of Man or Alien vs Hunter, I died a little inside.

  • Angela

    FAIL…. I was lucky enough to fine . "Santa Claus Conquers the Martians" on DVD about five years ago (and it's a childhood film my bother and I looked forward to watch at Christmas time) and have given it out to friends to watch over the years…EACH AND EVERY single person who's watched this film LOVE it. Yes, It's cheesy and over the top, but that's what makes it sooo damn good and fun to watch. This film doesn't belong on this list, at all!

  • Celidus

    How is Avatar not on that list?!? – Unobtainium, floating mountains, naturally occurring carbon fiber bone structure. Not to mention talking with their pony-tails and riding the flying reptiles plus cliche' and predictable plot. Avatar was at least ONE of the worst sci-fi movies ever made.

  • I would rather watch all these films back to back in one session than suffer through 20 minutes of Predator 2! the worst scifi EVER! as well as the worst sequel ever as well as top 10 worst movies ever. I also hated every pre Christian Bale Batman movie but I dont count them as scifi but as fairy tales for boys.

  • santa

    Great lsit. Im sure there are tons of other movies you could have included, Most notably "The Gates of Hell" – the grossest (funniest) puking scene you will ever see.

    i want to see plan 9 from outer space and santa claus conquers the martians they sound funny and the robot monster looks more adorable than scary he looks cuddly and sweet i like :)

  • Henkie

    I saw Battlefield Earth once, but the script sucks, the effects sucks, the characters suck and the plot sucks. Easy to say the whole movie sucks, but i heard that the book is good.

    • SFgod

      This list sucks more than those movies

  • declan harman

    can SKYLINE be added to this list

  • Ngobleus

    Well, nearly half of the list was MST3K fodder (Plan 9 was not used on the show because of the constant narration).

    One I thought I might see but didn’t was the Creeping Terror.

  • Ray Milland was also in “The Man With The X-Ray Eyes” which is quite bad as well

  • Way, way, WAY harder than naming the top ten of anything would be the worst ten and doing the worst ten of science fiction movies is pretty impossible. And I don’t know, Star Trek: The Final Frontier and Superman IV in the same breath with Santa Claus Conquers the Martians? Doesn’t that seem a little vicious?

  • peter8172

    “DUNE” based on Frank Hebert’s sci-fi novel

  • merrrr

    mega shark vs giant octopus deserves to be on here….

  • InsertGenericNameHere

    even though battlefield earth is bad (and I mean BAD) Gorath should be #1

  • Junior

    awfuls movies, the man with two heads can be in this list too

  • Please forgive the long post, but I felt I owe it as a homage to the worst sci-fi film ever made.

    When “worst movie” lists are assembled I believe you have to consider cost as a main factor. For example, can you honestly grade a move made by a high school kid with a camcorder for admission into film school on the same scale as a movie made by a major motion picture company with a multi-million dollar budget? In some cases, if the kid had the same budget his movie would have been many times better!

    Battlefield Earth had a large budget, professional makeup & special effects artists, and A-list actors….and it was terrible! Some of the B-movies of the 50’s or 60’s are so bad they are entertaining. I own a copy of “Plan 9 from Outer Space” and I have great fun watching it. When I saw “Battlefield Earth” I just felt embarrassed for everyone involved in making the film.

    What makes the movie bad is the story. Scientologists want you to believe L Ron Hubbard, the inventor of Scientology, possessed a god-like genius. People in the know realize he was nothing more than a charlatan and scam artist, and merely mediocre as an author. This movie, an adaptation of one of his novels, is proof that his mental capacity for logic is so lacking that he could rarely be considered the smartest guy in the room much less a super-genius. It is also proof that Scientology is not some amazing scientific breakthrough discovered after years of research as he claimed, but nothing more than a money making scam he dreamt up.

    The movie takes place in the year 3000, one thousand years since Earth was conquered by an evil alien race. Our planet contained an abundance of an element the aliens used for money, and they wanted it. The aliens consider humans to be as intellectually inferior to them as we consider dogs are to us. They kill off all the humans with the exception of the few they use as slaves to mine for the valuable element. Treated as slaves used only for manual labor for 1000 years, the humans have evolved to behave like animals. John Travolta’s character is the main bad guy who runs mining operations.

    Travolta comes up with a scheme to gain personal wealth. The Earth is toxic to the aliens. The areas they inhabit for mining are covered by massive, city-sized domes. Travolta decides to use Barry Pepper’s character, our hero human in the movie, to secretly mine the element outside of the domed areas. Travolta straps Pepper in front of a teaching machine. This machine implants knowledge directly into the subject’s brain via a laser beam through the eye. Knowledge that would take years of college could be transferred in seconds. Pepper learns the alien language in order for him to take orders from Travolta and lead fellow humans on the autonomous mining missions. While Travolta’s back is turned, Pepper jumps on the knowledge machine and learns of his human history and the history of the conquering aliens. At that point he comes up with a plan to overthrow the evil aliens.

    Sounds like a reasonable sci-fi plot, right? Well, hang on. Here are some examples of the poor logic that ruins the movie. Stop reading here if you want to watch the movie as spoilers are given.

    What is this valuable element the aliens use for money. Coincidentally, it is gold. Yes, the same element we humans use for money just happens to be the basis of the alien currency. How convenient.

    Instead of mining for gold, Pepper trains his fellow human slaves to fly fighter jets to fight against the aliens. It’s been 1000 years since the USAF base has been active, and all human civilization was destroyed by the aliens. However, the electricity is still available, the machines still turn on and everything functions as normal.

    The human slaves have been treated as animals for 1000 years. They were forbidden to read or write. They have not been exposed to technology of any kind. When handed a laser rifle carried by the aliens they are too ignorant to even fire it. In spite of all this they have no problems jumping into a flight simulator and learning how to become a skilled fighter pilot in a matter of days. (Remember, Pepper was the only human exposed to the learning machine.) Even today it takes months for the USAF to train a pilot, and years for them to become proficient.

    Pepper’s crew has a quota to fill. They are dropped off at the mining site by drones, and when they are picked up they are expected to have a certain amount of gold from their mining activities. Instead of mining Pepper uses the time to train his rebels as fighter pilots. How does he fill his quota? By taking gold from Ft. Knox. Yep. The aliens didn’t even know it was there.

    At one point of the movie Travolta tries to intimidate Pepper by flaunting his superior intellect. He shows Pepper an old library that was destroyed in the alien attack. He said the piles of books contained all the knowledge of humans, and even with all that knowledge the humans were so inferior that they were only able to withstand the alien attack for six minutes. This establishes that Travolta and the aliens knew about our human society and civilization, their accomplishments, and the capabilities of our weapons. It was this knowledge that enabled them to realize humans were no match for their superior alien technology. Therefore, they knew that they could easily conquer Earth and take all of their gold. They knew all of this….except where the humans kept the gold!

    Yes, here is the level of logic from the superior intellect of L Ron Hubbard. The entire purpose of the alien invasion was to strip all the gold from the Earth. To prepare for the invasion they studied us to create a battle plan. They studied our social advancements, they studied our physical capabilities, they studied our military capabilities, but never once during all this studying did they bother to find out where world’s gold deposits were located. Wow. What makes this the worst sci-fi movie in history are gaps in the plot the size of super-massive black holes, and this is the worst one.

    So while some of the humans were training to be fighter pilots others would take a helicopter to Ft. Knox to grab some gold to make it look like they were using their time mining.

    After the humans were adequately trained they jumped into the fighter jets that surprisingly worked after sitting untouched for 1000 years, and launched an attack on the aliens. Earlier in the movie we are told that the alien technology is so superior to humans that all the armies of the Earth were defeated in six minutes. In spite of this technological gap, the humans with the animalistic mentality and days of training in their 1000 year old fighter jets were successful in their attack and killed all the aliens.
