Other mistake: In the final scene of the movie, Megan starts a boat motor and uses the propeller to hit Jason in the face, who has been chained down underwater. But if Jason can only barely reach her foot from underwater, there's no way the boat propeller is underwater far enough to reach his face. (01:17:50)
Suggested correction: The boat was driven a good ways, it's not like they were shallow and then all of a sudden deep. They were deep for a little bit. I mean not so deep like the ocean, but it was a good enough ways for someone to drown. Megan is tall for a girl and Jason is a big guy and the propeller is right at his head/neck.
You are very much mistaken. The boat propeller is too high to reach Jason's face.
Other mistake: When the autoguns fire at the aliens for the second time, there is a flashcut of an alien being blasted apart. Watch closely; it's the same clip of the alien that Vasquez shot and subsequently sprayed Drake with acid. (01:18:00)
Other mistake: When Seth comes out of the pod for the second time and the girl is watching him she moves her leg reveling panties. However, Seth comes over and they start intercourse. How? He doesn't even move her underwear to one side.
Other mistake: The Hitcher reverses his pick-up truck out of the gas station after he drops the lighted match. His wheels, wheel arches and perhaps the underside of the truck would have been soaked in petrol as he drove over the gushing pumps. So as he was burning rubber during this manoeuvre - this would have ignited the petrol on his truck.
Other mistake: Leatherface attacks the Mercedes. The pick up is driving backwards, the Mercedes forwards. The Mercedes should easily be able to outpace the pickup.
Other mistake: There is a scene at the beginning of the movie where the two main male leads are walking near a frat house having a party. The shot with the error starts on a frat banner and then pans down and across to the female lead (Jill Whitlow) and stops with her in the center of the screen. At this point, her legs are transparent.
Other mistake: When the family is leaving and the door is shut you see the floor lock (common in older homes) on the door engage. When Brad goes back in through the window you see him run down the stairs. He gets to the door and unlocks 2 locks on the upper part of the door but not the floor lock.
Other mistake: As Packard backs out of the cemetery there's no damage to his car, despite crashing through an iron fence and headstones.
Other mistake: Hendershott fires the L.A.W., then gets killed. Nobody reloads it, but Wanda fires it at the beer truck as she dies.
Other mistake: Maureen cuts her wrists with a razor blade. Days later, no bandages or scars.
Other mistake: Taylor parks his car in Cuesta Verde, next to a couple of crates next to the pilot's door. He steps down and walks straight without looking down, which is impossible for he should have tripped.
Other mistake: Walter Paisley is cleaning the floor and encounters the first robot. The whole reason the robots are patrolling at this point is that the shopping centre is supposedly closed to customers, as it is nighttime. However in this scene you can see quite a few people shopping on the upper tier of the mall above Paisley.
