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. (00:17:30 - 00:20:40)
Visible crew/equipment: 25:05 into the second episode of the TV miniseries, in the scene where Nick Andros and Tom Collins meet Julie from the drug store, the boom mic is seen for several seconds at the bottom right of the screen after Julie crosses the street to meet them.
Continuity mistake: When Lestat slices the whore's wrist at the hotel, blood drips everywhere on the couch, but when she stands up in the next shot, there is no blood anywhere. (01:56:12)
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. (01:15:20)
Visible crew/equipment: When Julie says "It's probably just your nerves" then Heather replies "Nerves?!", above Heather's head you see a boom mic dip down into view. (00:12:25)
Continuity mistake: When the Leprechaun is telling his slave who tried to run away that it was his 1000th birthday. The scene is set a very long time before the first film, but in the first film he tells the cop that he is 600 years old.
Continuity mistake: Even though the moon plays a leading role in the movie its phases get mixed up in a big way: Before Will has his first night out as a semi-wolf there's a shot of a half moon. That's not only just a few days after the full moon when he was bitten, but it's waxing to boot. In the next night, after Will calls Laura, apologizes for his vanishing, and asks her out for dinner there is another shot of a slightly fuller moon, but now it's waning. However, two days later near the end, when Will is locked up in the barn, the moon is full again. (00:46:40 - 01:05:05)
Other mistake: When Lamont walks into the alley to avoid being followed by one of Khan's warriors, he makes himself invisible, and his shadow vanishes as well. It's well noted at the beginning of the film that his shadow is always visible even if he isn't. Therefore, his shadow should still be seen on the ground and give him away.
Audio problem: When the man with the peg leg is trying to resist getting a shot of anti-smallpox serum from Professor Waldman, he yells, "You're not sticking that in me. You're not sticking that in me." But if you look closely, you can see that his lips are not moving. (00:32:45)
Visible crew/equipment: When the spheres fly through the air you can see a "dot" following which is the camera.
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.
Visible crew/equipment: During the final stand off between Decapitron and the Totem in Puppet Master V, you can see about three strings yank the Totem back, as he is blasted by Decapitron's electricity.
Continuity mistake: When Brenda is spraying Johnny with the hose, the position of his newspaper bag strap changes drastically from shot to shot.
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?
Visible crew/equipment: You can see the strings on Pumpkinhead when they are killing him at the end.
Continuity mistake: When Cane's agent gets out off the bookstore and crosses the street, the cars keeps changing all the time between shots.
