Best horror movie deliberate mistakes of all time

1

Cube (1997)

Cube picture

Deliberate mistake: Leaven spends too much time thinking about if 645 and 372 are prime numbers to be believable. But she knows the factors of 649 and the result of 26 to the power of 3 almost immediately. Plus anyone with any maths knowledge whatsoever would know that any even number (or one divisible by 5) can't be prime, so 645 and 372 could be dismissed without even thinking about it.

Ghost Ship picture

Deliberate mistake: At the beginning and especially at the end, Julianna Margulies spends extensive time in the ocean, wearing nothing but cargo pants and a T-shirt. Considering the movie takes place just off the Bering Strait, wouldn't she have quickly frozen to death?

The Lost World: Jurassic Park picture

Deliberate mistake: When the ship crashes into the dock, all of the scenes leading up to the crash and after it show a clear view across the harbor as we can see lights and land on the other side. It's not until the ship is about to crash that a thick and dense fog appears and disappears within a minute to mask the ship to create a more dramatic effect.

House on Haunted Hill picture

Deliberate mistake: When Eddie and "Jennifer" are walking around the house alone, "Jennifer" is trying to tell Eddie that she's really Sara. But By the time she is explaining that her name is actually Sara and not "Jennifer", Eddie has disappeared. She doesn't find him until later... But from the moment she finds him (and he is talking to her) he calls her Sara... but he never actually heard her say that. He was gone. Also, after they all get back together, a few of the other people start calling her Sara as well....but no one actually heard her say that her name was Sara.

Psycho picture

Deliberate mistake: When Norman picks up Marion's body to carry it to his trunk, a bra is visible through the shower curtain. Gus Van Sant included this goof in his 1998 remake.

Duel picture

Deliberate mistake: Just before the truck slides off the cliff edge, you can see that the truck's cab door is open where the driver jumped out.

I Know What You Did Last Summer picture

Deliberate mistake: The film supposedly took place in the Coastal Carolina region. This is a geographically flat area, called a coastal plain. In the beginning of the film, the kids were driving along ocean cliffs, which are not present in the Carolinas. Obviously, this was filmed in California.

Alien (1979)

Alien picture

Deliberate mistake: When Ripley is trying to deactivate the self-destruct mode, the instructions she follows on the container are actually just the French interpretation of the instructions she read to activate self-destruct before.

Jack Vaughan
Jason Goes to Hell: The Final Friday picture

Deliberate mistake: If you watch closely, it is painfully obvious that in the beginning, when Jason is getting shot up, they are just repeating the same shot from different angles.

Final Destination 3 picture

Deliberate mistake: There are a number of things wrong with the roller coaster scene (besides the obvious impossibility of a crash like this actually occurring):1) The restraints use ratchets to lock, not hydraulics. A coaster of this type wouldn't even have any hydraulic lines.2) No roller coaster has restraints that lower by themselves.3) The attendants didn't check all the restraints. This is ALWAYS necessary, on ANY ride.4) On any roller coaster, the Dispatch button (or "Start" in the movie) must be held down until the train is clear of the station. This is a safety feature to make sure the attendants are clear of the moving train. If the button is released before the train is clear of the station, it will stop.5) At the bottom of the lift, the lift chain curves to follow the track into the station. This is impossible, a lift chain cannot curve horizontally, only vertically (normally at the top of the hill).

Dracula 2000 picture

Deliberate mistake: During the ceiling sex scene, Lucy's hair lays flat against the ceiling with no effects of gravity while Dracula's hair hangs towards the floor fully under the proper force of gravity.

Jeepers Creepers 2 picture

Deliberate mistake: When the Creeper gets stabbed throught the eye with the javelin, it goes through the front of his eye, but when it comes out the other end the eye is facing backward.

Pitch Black picture

Deliberate mistake: In Paris' death scene, he blows alcohol onto his torch that illuminates the creatures around him. However the area is still illuminated after the light from his torch has disappeared.

THGhost
Hellraiser III: Hell on Earth picture

Deliberate mistake: When Pinhead is killing the patrons at the club and they are running away to try and escape, you can see some of them laughing instead of screaming like they should be.

SAZOO1975
Darkman picture

Deliberate mistake: There is just too much movement and detail in the synthetic skin masks. Peyton lost a large portion of his face in the explosion, and cannot make much expression with his own face, but somehow he can make the masks move perfectly just like a real face.

The Ring picture

Deliberate mistake: When Noah drops Rachel off at the ferry he drives right up the the gate at the dock which is strictly prohibited by Washington State Ferries. The only cars allowed in this area are the ones who are boarding the boat, no exceptions.

Dressed to Kill picture

Deliberate mistake: Has there ever been a more obvious body double than the one used for Angie Dickinson in the shower scene? Not only does the top of every shot stop right at the collarbones, she is much taller than Dickinson, she has a much deeper tan and (of course) her breasts are much, much bigger.

The Order picture

Deliberate mistake: There is one scene in the movie where Heath Ledger reads a Latin sentence in a book. As he is translating the sentence, he goes over the words one by one with his finger. This would never be possible in a Latin sentence, because words in Latin are never - I repeat: never - in exactly the same order as in English. Words that actually belong together can be placed on opposite ends of a sentence.

Bride of Chucky picture

Deliberate mistake: When Tiff (as a doll) lights her Zippo you don't see her clicking the flint, even though one can hear a 'clicking' sound.

Seed of Chucky picture

Deliberate mistake: When Jennifer is being pursued by Tiffany in her house, Jennifer trips over her stiletto. When she falls you can tell it is a stunt woman as she is a bit shorter than Jennifer Tilly (also look at the ass). Revealed in DVD commentary.

A Nightmare on Elm Street picture

Deliberate mistake: As Nancy and her Mum are leaving Rod's funeral, you can see the shot of them leaving the funeral has been sped up. Watch the Volvo "jerk" as it pulls away as the speed is rapidly increased.

The Exorcist picture

Deliberate mistake: Father Merrin says, "It is He who commands you", and we hear and see the ceiling crack above his head. In the next shot we see the ceiling above him and they are no cracks in it, but four shots later we see the exact same spot and now cracks appear even though we hear no more cracking over-dubs after the first one.

Resident Evil: Extinction picture

Deliberate mistake: During the scene where Carlos and L.J. are searching the motel, L.J. sees a zombie which turns out to be a reflection in a wall-length mirror. L.J. shoots, breaking the mirror and realizing his mistake. But, if he had been standing in front of the mirror as shown, he should have seen his own reflection standing there as well. This was done as an homage to a similar encounter in the original game.

Plan 9 From Outer Space picture

Deliberate mistake: They keep using the same footage of Bela Lugosi walking in the cemetery, even the cars driving by out on the road are the same.

House of Wax picture

Deliberate mistake: Due to the thin tissue and blood supply to the lips, after Carly ripped the superglue from her lips she should have bled profusely, requiring steady pressure for a minimum of five minutes. However, that would have obviously slowed the tension of the movie too much.

Valentine picture

Deliberate mistake: Paige's stunt double being thrown into the hot tub is obvious.

The Amityville Horror picture

Deliberate mistake: In the beginning, the police chief says "The six members of the family were found last night, in bed, shot and killed." As he says this, look to the left of the screen. In the background, the real Amityville house (dark brown with white windows and trim) is shown instead of the house used in the rest of the film. That segment was from actual news footage of the murders from 1974; apparently, the director didn't want to recreate it.

Predator 2 picture

Deliberate mistake: When King Willie is confronted by the Predator in the alley the Predator approaches him cloaked stepping through the puddle of water. You can see his footsteps causing the water to splash up. However, you can see the water splash up and go through his foot. The Predator is only cloaked, not intangible so the water should have splashed upon his foot, not go through. Water against his foot would be visible too, even though he is cloaked.

Deliberate mistake: The cocaine dealer who was attacked by zombies returns after the group arrives. He is wearing the denim jacket he took off when the zombies attacked him.

Randy DeShong
Toolbox Murders picture

Deliberate mistake: After the killer nails Shannon to the ceiling, he apparently has time to remove all the nails from the wall where he originally shot her, spackle, paint and clean up all the blood before the police arrive and examine the apartment.
