fact checked by Jamie Frater

It’s been a while since a new Jason movie featured on the big screen or a green and red striped jersey brought terror to our dreams. While those horrors have been left behind in their own era, a host of new scary movies exist to keep us shivering. And as with most movies, the fan theories follow close behind. WARNING: spoilers ahead!

10The Cabin in the Woods

Cabin in the Woods (2012 Movie) – Official Trailer – Chris Hemsworth & Jesse Williams

You would be forgiven for thinking of The Cabin in the Woods as the horror movie starring Thor and the hot doctor from Grey’s Anatomy. This popular horror film surprised audiences in 2011 with its fresh approach and massive plot twist at the end.

However, not all viewers were convinced that the twist at the end was all it seemed to be. A fan theory has it that Chris Hemsworth’s character, Curt Vaughan, was in on the plot from the beginning. Proof of this theory is presented in the fact that Curt is the one who gets the group of friends to go to the cabin. Curt is also the only one who doesn’t choose a summoning object down in the basement.

More ‘proof’ indicates that Curt knew his girlfriend Jules had to die first according to the rules, so he made sure to get her alone so the zombies could kill her. It is also thought that Curt would have been given the title of ‘hero’ if he played along with the Facility.[1]

9The Texas Chain Saw Massacre

The Texas Chain Saw Massacre (1974) – Movie Trailer

The Texas Chain Saw Massacre 1974 classic horror is one of the creepiest movies on this list. The killer, Leatherface, dons a mask made of human skin and runs around with a chainsaw and an insatiable bloodlust. Not to mention the Leatherface character is based on real life murderer, Ed Gein.

As such, it has always been assumed that Leatherface is a man, but a Reddit fan theory has it that the crazy murderer might in fact be a woman. Proof of this is said to be the way the killer applies lipstick and blusher to another mask. Leatherface also goes mental when the freezer is tampered with and makes very high-pitched sounds for what is supposed to be an above-average sized man. It is also alleged that since Leatherface prepared the food and probably ‘decorated’ the creepy house depicted in the movie, he is probably a she.[2]


Halloween – Official Trailer (HD)

The most recent Halloween movie was a huge box office hit in 2018. In it, Michael Myers allegedly crashes the bus he was being transferred in, to return to Haddonfield to kill a bunch of people. He also goes after Laurie Strode, who has turned her house into a fortress.

Eagle-eyed viewers were quick to notice something off about Laurie, however. While sitting in her truck, drinking, she waits for the bus to leave for the maximum-security prison. She then pitches up at a family dinner drunk and starts crying. A fan theory has it that is wasn’t fear causing her to react like that, but guilt. The theory goes that Laurie, and not Michael, was the one responsible for the bus crash. It is also said that her almost non-reaction to the news report on the crash is a further indication that she planned the whole thing. Why would she do such a thing? Well, because she had been waiting for her fight with Michael for 40 years and wasn’t about to be unprepared for when he arrived at her house.[3]

7 Us

US Trailer (2019)

Michael Myers has also been tied to the popular 2019 horror movie Us. The sequel to Get Out has spawned quite a few fan theories including one that says Michael is a Tethered and was swapped with a clone and trapped for 60 years.

Not only has Jordan Peele, writer and director of US, referenced Halloween during several interviews about his movie, he also mentions the rabbits that feature in the film and how if you should put a rabbit brain in a human body, you’d end up with Michael Myers. What further gets the theory going, is that Michael doesn’t talk, but rather grunts much like the Tethered in Us. Also, in Halloween Resurrection it is revealed to viewers that a tunnel system runs under the Myers house linking to the basement and ultimately enabling the clone swapping.

Moreover, Michael’s psychiatrist, Dr Loomis, tracks him using a ‘Rabbit in Red’ matchbox and describes his patient as not having a soul. Which pretty much describes the Tethered.[4]

6 Hereditary

Hereditary is arguably the most disturbing entry on this list. There is bleakness and gore and shock value all culminating in a terrifying reveal involving a demon king named Paimon.

Fans were quick to come up with theories involving aspects of the movie, such as linking it to Midsommer (another disturbing horror flick by Hereditary director: Ari Aster). The theory says that since both movies feature cults, they must play out in the same universe. Some fans are also convinced that the couple walking past Annie in Hereditary is the one and only Dani and Christian from Midsommar.

Another popular theory supported by many fans says that none of the horrifying things in the movie, such as Charlie’s decapitation, actually happened. Instead it was the manifestation of both Annie and Peter’s mental disorders.[5]

5 A Quiet Place

A Quiet Place (2018) – Official Trailer – Paramount Pictures

A Quiet Place took what we knew about horror and turned it on its head. Featuring silent characters and monsters reminiscent of the Demogorgon in Stranger Things, this movie made for a unique cinematic experience. Many movie-goers reported feeling uneasy throughout the movie because of the ongoing silence.

In the movie, the monsters are extremely sensitive to noise and attack anyone that makes a sound (as is evident in the very disturbing scene with the little boy and the toy rocket). Hence the silent characters.

These monsters, if one goes by the newspaper clipping on the wall, came from outer space when a meteor hit Earth. However, some fans think that is only a red herring and the creatures are in fact biological weapons left over from WWIII. Others believe that the only way the creatures could have spread so fast if they did indeed crash in only one spot in Mexico, is with the help of the meteor impact. If they had crashed during the spore stage of their lifecycle the impact would have sent the spores flying to the upper atmosphere where they would have caught a ride to locations all over the US.[6]

4 It Follows

It Follows Official Trailer 1 (2015) – Horror Movie HD

When it comes to psychological horrors, It Follows is a great example of how to do it properly. Rated 96% on Rotten Tomatoes, most reviewers agree that this movie is truly frightening without trying too hard or relying on tired jump scares.

The plot of the movie centres around a curse in the form of a shape-shifting entity passed on to Jay Height after she has casual sex with a guy in the backseat of his car. She then must pass on the curse to another man, otherwise she will be killed by the entity that presents itself in the form of the loved ones of its victims. And so on and so forth.

A twisted theory appeared on Reddit that says the young people in the movie, running from the sinister shapeshifter, were kidnapped from different decades by demons and sent to Hell. On Earth, they had been replaced by changelings. This would mean the monster that follows Jay in the movie, is just another inhabitant of Hell. And the monster doesn’t choose its own form, but rather the victim determines its shape by what may have happened to them in the past such as abuse, rape, attempted murder etc. Since Jay has suffered a sexual assault, the monster chasing her takes the form of a naked woman.[7]

3 The Babadook

The Babadook Official Trailer #1 (2014) – Essie Davis Horror Movie HD

The Babadook is yet another psychological horror that features a creepy kid and even creepier monster. When labor pains overtook Amelia, her husband drove her to the hospital only to get into an accident. Her husband didn’t make it and the movie follows Amelia’s struggle to cope with being a single parent. She reads a book about the Babadook to her son but starts feeling uneasy with the content, especially when her son claims that the Babadook haunts him at night. Amelia then tears up the book and throws it in the bin.

The book shows up on their doorstep, glued back together, and things take a turn for the worse in the household. It seems that the Babadook possesses Amelia with her voice changing during fits of rage. She also kills their dog and eventually goes after her son. When she vomits up black goo, it seems that the Babadook has lost, but instead it runs to the basement where it seems to be fed maggots by Amelia at the end of the movie.

A fan theory has it that the Babadook is a physical manifestation of Amelia’s hatred for her son, since she gave birth to him on the same day her husband died. When the Babadook is heard making weird noises in the movie, Amelia’s rage is evident, giving more weight to this theory. Another theory says that it is not rage, but Amelia’s intense grief that brings the Babadook to life.

A very popular theory claimed that the Babadook is gay, which was eventually acknowledged but not entirely confirmed by filmmaker Jennifer Kent.[8]

2 Carrie

Carrie (1976) – Official Trailer (HD)

Carrie is a lesson on the consequences of bullying. And a very disturbing movie to boot. Carrie started out as Stephen King’s first published novel that spawned a film in 1976 and then a remake in 2013.

As with most Stephen King novels and movies, there are many theories surrounding the plot. In this case the main theory seems to be that Matilda, the main character in the novel of the same name by Roald Dahl, grows up to be Carrie.

After Miss Honey and Matilda move to Chamberlain, Maine, they change their names to Margaret and Carietta. Much like Carrie’s mother, Honey/Margaret becomes very religious which leads to Matilda/Carietta hiding away her telekinetic abilities. Which then leads to the start of the story of Carrie, according to theory. This would essentially mean that Matilda is the prequel to Carrie. More proof that these two stories take place in the same universe comes in the form of a car named Christine (another Stephen King title), which is a 1958 Plymouth Fury sold by Matilda’s father. The car caused the death of a passenger, leading to Matilda’s father being arrested and Miss Honey and Matilda’s move to Maine.[9]

1 IT

IT – Official Teaser Trailer

The craziest theory by far, on this list anyway, is the one that connects Disney’s Mary Poppins and Stephen King’s IT. Considering that Mary Poppins is a sweet lady that flies around with an umbrella and IT is a killer clown, it might seem ridiculous. However, the theory points out that Poppins and IT share a similar power. They are able to tap into children’s innermost thoughts, whether it be for good or evil.

Both movies feature a young boy named Georgie. While Poppins returns to Cherry Tree Lane after 25 years and relies on children’s joy to keep her energy levels up, IT returns to Derry every 27 years and uses the fear of children to keep his power levels up. In both movies, the children’s encounters with IT and Poppins seem to fade from their minds. Not to mention, Poppins and IT both seem to like dancing. The final thread connecting these two movies comes during the scene where the characters in Mary Poppins grab balloons and float away. Since “floating” and “balloons” are synonymous with IT, the theory seems plausible to many viewers.[10]
