Best horror movie mistakes of 1994
Continuity mistake: In the first scene when the girl is walking down the sidewalk she passes by a female zombie wearing a brown shirt twice, and she passes by a male zombie in a blue and white shirt, and a few seconds later he's with a group of zombies that carjacks her in the woods outside of town.
Visible crew/equipment: When Francesco and 'she' are in the cemetery together and the little blue flame-beings gather around to watch them, you can see the wires they're suspended on several times. This is most apparent when Francesco sees the first one (moments before seeing 'she' at the fountain) and also just before they are all frightened away.
Visible crew/equipment: When Leatherface is chasing Jenny, she gets into a couple's caravan. After Leatherface tries to get in, it cuts to an exterior shot and as Leatherface is running along with the caravan, in the window behind him you can see a crewmember with a cap on, running behind him off-screen.
Continuity mistake: In the water tank sequence Cranston dives to the bullet holes to get air. When he dives down there is a camera shot looking up at him from the bottom of the tank showing that there is plenty of air left at the top, no doubt left there so that the actor would not drown. And; for the sealed tank to fill completely there must have been a way for air to escape rapidly from the top. When the tank was full water kept pouring in and would have escaped the same way. When Margo arrives there is no water coming off the top of the tank.
Revealing mistake: As Mary, Sam, Jarvis and Andrew are speeding away from the TV station, one of the boys from the UFO crashes his bike head first into the car. This causes the boy to crash through the window. When he does this the window shatters like a plate glass window instead of the safety glass that is a standard to be used for vehicle windshields.
Plot hole: The reason given for the cop having psychic powers is that he has a well-developed hypothalamus - but that is the part of the brain responsible for homeostasis (maintaining a constant internal environment for the body). So even if you had a particularly well-developed one, you might sweat more when you get hot but how could it make you psychic?
