Best horror movie factual errors of all time

Hollow Man picture

Factual error: Gorillas are strict herbivores. So why does Isabelle eat a rat at the beginning of the film? The serum may have turned her into a crazed killer, as it does with Sebastian, but it hasn't changed the structure of her teeth and palate, biochemistry of her digestive system and so on, all of which would be required. She might kill or torture the rat, but she'd never eat it.

The Mummy Returns picture

Factual error: When Brendan Fraser & his son are running to reach the pyramid before the sun hits it, the sunrise line approaches the pyramid along the ground, but the sun would naturally have hit the pyramid at the top first and worked its way down to the ground. [Some people insist on trying to correct this - think of it this way. If the sun's illuminating the ground from way up in the sky, what's keeping something higher up than the ground in darkness?] (01:34:40)

Suggested correction: Despite the additional comments this posting is wrong. The terminator line - the distinct boundary between sunlit day and dark night - moves horizontally across the surface of the earth, from east to west. It is perfectly feasible for the land behind Rick (i.e. to the east) to be in bright sunlight while the pyramid - to the west - is still in darkness. What is not feasible is anyone outrunning the terminator line, which moves at around 1500 kmh in the latitudes they are in.

Abbott and Costello meet Frankenstein picture

Factual error: When Dracula is about to bite the neck of his female assistant you can plainly see him in her vanity mirror and as all good horror fans know, you can't see a vampire in a mirror, especially Dracula.

The Texas Chainsaw Massacre picture

Factual error: This movie states that it is during the year 1973, yet in the beginning of the movie when they are driving in the van they are listening to "Sweet Home Alabama" by Lynyrd Skynyrd. This song was not released publicly until 1974. (00:03:10)

Species picture

Factual error: Fitch, who professes qualifications in biology, genetics and biochemistry, says that they made Sil female because she's a natural predator and so she'd be more docile. He should retake his finals. In every single species of predator on earth - every single one - the females are the hunters, aggressors and killers. The males may be socially dominant but they are the 'docile' ones. There are no exceptions - and no human DNA was used to create Sil - they used synthetic DNA based on the instructions transmitted to them.

Suggested correction: They never said Sil was a natural predator when they created her. She was half human and half alien and it was their belief that human females are more docile (i.e. more motherly, more gentle, more empathetic, and less aggressive than human males). Although the reply to "more docile and controllable" was "you guys don't get out much", meaning that girls aren't that docile and controllable.

Anaconda picture

Factual error: During the first battle with an Anaconda, the 55-gallon fuel drums lashed to the deck of the riverboat are swept over the side, where they sink to the bottom of the river. This plot device drives the rest of the movie, since the boat must make a dangerous detour through "Anaconda country." There is just one small problem with this: Fuel drums full of diesel fuel or gasoline float on water. The fuel in them makes them buoyant. It would have been a simple matter for someone to get a rope or a boathook and retrieve the fuel drums before they floated away.

Factual error: When the cop saves the girl from the mob of locals, his car tires squeal as he accelerates away, but the car is on loose dirt, which makes the squealing impossible.

Friday the 13th picture

Factual error: At the climax of the movie, Alice swings the machete at Mrs. Voorhees and decapitates her. When the blade makes contact with Mrs. Voorhees' neck, her head flies off at an incorrect angle, as though the cut began on the opposite side.

Prometheus picture

Factual error: The type of surgery shown made by the machine transversely cuts the rectus abdominis muscles. Besides not being a standard surgical incision in order to "remove a foreign body" as stated, it seriously damages important muscles of the abdominal wall making any immediate active mobilization of the trunk virtually impossible, even under strong analgesia.

Ghost Ship picture

Factual error: The gold bars that the crew finds must be some new type of light weight gold. There's no way that Julianna could stuff a gold bar in her back pocket and then pull it out and toss it on the table and Greer simply tosses it back and forth like it was plastic. A gold bar weighs around 27 pounds, you definitely wouldn't be tossing it around. (00:42:05 - 00:47:50)

Jeepers Creepers picture

Factual error: When the kids are getting hit from behind by the truck, cut to a side shot of them in the car, the boy's body moves forward, while the girl's body is more properly propelled in a backward motion relative to the car. This happens several times.

Mommie Dearest picture

Factual error: When Christina mixes a drink for one of Mommie's "guests" she bends down behind the bar to put a bottle back. Sitting on top of the bar is a Trigger Sprayer bottle of "Fantastick" - a spray that did not come out until the late 60's.
