Other mistake: Michelle Rodriguez's accent changes several times, not only throughout the movie, but sometimes within the same scene.
Other mistake: When the zombies come out of the river and start marching, look closely. The first zombies to come out wear wet clothes, but the ones in the back are dry.
Other mistake: Just as the gang are off to pick the plants they need Faith goes off to talk to Daniel. While she's there the others woop and laugh, but they do it once and it's recorded. It's played 3 more times, straight after each other. Sounds slightly stupid.
Other mistake: In the 30th Anniversary version with new footage it is revealed that the first zombie we see (the one that kills Johnny) died in the electric chair. If that's the case, he should be bald with a large burn on his scalp, but he has a full head of hair.
Other mistake: Toward the beginning, when the characters wonder aloud what the rumbling noise is, someone suggests that it's the ventilation system, to which Rennes responds "No vents." However, in the passages between rooms there are panels with ventilation slits in them (which you can plainly see even as Rennes says the line), and it's pretty impossible that the characteristically level-headed and observant Rennes wouldn't have noticed that.
Other mistake: When Dana enters the hall after being attacked by Pin Head, the door opens out into the hall, but it should open into the room, not out into the hallway. (00:57:00)
Other mistake: In the scene where Lestat and Louis are in the tavern, Lestat kills the barmaid. He says "She's as dead as a doornail, my friend", and rests her head on the table. He then drops some coins onto the table, and the "dead" woman's eyes flicker in reaction. (00:17:55)
Other mistake: The exhaust of the space ship is so strong that it knocks down Jeff and Paula to the ground, but their hair doesn't get changed at all.
Other mistake: When the captain comes face-to-face with the Thing for the first time, the upper right frame becomes blurred once the door starts opening until it closes followed by a scene change. Very odd except maybe they were trying to hide the minicharges to create the bullet holes after they close the door. The implanted charges are very visible when the scene is not blurred. Also there is a small charge in the wooden frame of the door near the door handle. (00:57:32)
Other mistake: The drip-meter that is supposed to administer Jigsaw's medication is not turned on. Anyone who has spent time in a hospital and seen one for real knows that a lot of numbers are shown on the displays when it is running to show medication status. (00:13:50)
Suggested correction: It's not specifically stated that the machine is in use. That's just an assumption. It could be set dressing he's using to enhance the perception of his condition.
Other mistake: The same shot of two guys looking at a computer while sitting outside on the school campus is used in two different scenes. (00:02:15 - 00:11:35)
Other mistake: When we see the body of Liz Stride after her throat has been cut, the blood is bright pink. This may be due to the light shining on it, but it's still pink. (Surely by then, the blood would have turned brown after mixing with the oxygen?).
Other mistake: During the credits, in the shot of the diner, the asian man sitting to the right glances right at the camera. (00:02:00)
Other mistake: When Woods gets shot by the nails fired by the small robot, the amount of blood in his sweater keeps changing during the following scenes.
Other mistake: In the shower scene, Marion Crane's palm looks water wrinkled as if she's been in the shower for quite a long time even though she was only in for a few moments before Norman stabs her. Also, when Norman drags her out of the bathroom, Marion's legs are stiff and together and she has her toes pointed.
Other mistake: No warehouse would stack their products in a labyrinthial way. They would be stacked in rows. (01:05:30)
Other mistake: When the mother, Pamela Fitzgerald, opens the freezer to put in the meat, she is distracted by Bridgette. In the freezer, we see the corpse of Trina. Look at Trina's eyes when we first see her; they seem to widen while Pamela is holding a pack of meat above her.
Other mistake: After Ethan crashes the Impala, he shoots at Keifer to make sure he's dead. Keifer's head and torso are on the hood of the car, but the shots break the back window on the driver's side. (01:13:05)
Other mistake: There's no way for Shelly to fit his masks, a speargun and other items in the small box.
Suggested correction: No, but we don't know exactly what he might have brought. The first time we see him they're picking up Vera, so it's most likely he brought another bag that could contain the items. He only said to Vera that the small bag was his whole world, but he just met her (Andy mentioned he got him a date for the trip) and he's trying to get her to warm up to him.
Other mistake: In the scene when Robert gets caught up in the trap by Grand Central Terminal, there are no traffic lights on the upper street that they show him being suspended from.
