Other mistake: When Ripley is trying to deactivate the self-destruct mode, the instructions she follows on the container are actually just the French interpretation of the instructions she read to activate self-destruct before.
Other mistake: When Max's wife goes to get ice cream, you can see Max's black Interceptor in the driveway of one of the house, right before one of the bikers loses his hand.
Other mistake: When Larry Crocket runs out of the house in his underwear and gets attacked by Barlow, later when the police find him his clothes are in the car. How is that possible when he ran out of the house with his clothes still inside?
Other mistake: When George is in the basement, his son starts walking down the stairs. Suddenly a light bulb shatters right next to the boy's head, he screams, and falls violently down the stairs. But when it cuts to George coming over, he's just walking at a normal pace as though nothing happened. (This is just after they move in, before the evil spirits take hold of George, so there's no reason for him not to be alarmed.).
Other mistake: The Rogues stop to make a phone call at a candy store. The meeting in the Bronx was at midnight so it's got to be 2 or 3am. What on earth is a candy store with a little girl working there doing open at that time with nobody on the streets?
Other mistake: In the scene where Frank Morris first starts to dig using the nail clipper, he stands up in his cell, turns off the light then bends down to start digging, however the only light coming into the cell would be on his right, but the shadows from his head and bars appear to be from a light directly behind him.
Other mistake: In the boat chase on the Tapirape, Bond's torpedo hits the enemy boat either on its back or left side, but neither are damaged by the explosion in a subsequent shot. (01:18:15)
Other mistake: Miss Froy writes her surname in window condensation on the train before she is abducted, where it's supposed to have remained visible for hours, which is dubious in high summer. Then it all of sudden disappears as they go through a tunnel, but why would going through a tunnel cause condensation on inside of train window to all of a sudden disappear?
