Other mistake: When Tommy Lee Jones calls up the asset as he lands in Las Vegas you can see him holding the mobile phone upside down with the camera near his mouth and microphone up.
Other mistake: When they raise the temperature of the room with the facehuggers in, once the room is at body temperature, they open the door onto the much colder corridor. This would have immediately dropped the temp in the facehuggers' room.
Other mistake: According to the big photograph in their respective offices Bressler and the DA share the same pair of little daughters. (00:17:05 - 01:10:10)
Other mistake: When the monk arrives with Jackson and the others at the gate leading into the secret entrance of the ships, the countdown to impact timer reads about 28 minutes. It is highly implausible that the group, which contains elderly and small children, are able to get to the top of what looks to be a 100 story staircase in less than 15 minutes without breaking a sweat. Once they are inside the hatch, the countdown to impact timer reads about 13 minutes.
Other mistake: During the scenic elevator rescue scene, a helicopter lowers the Fire Chief down to connect a cable to the top of the elevator. The cable is seen to be hanging no more than three feet from the side of the building. If this were the case, the helicopter's rotors would be hitting the building. (02:04:10 - 02:06:10)
Other mistake: When Mike goes to Marcus's house to apologize, as Marcus lets Mike in and they walk through the house you can see the corner of a very nice built-in pool through the glass doors, even though a large part of the beginning and the end of the movie take place in Marcus's '$3900' portable pool and its subsequent replacement. (01:34:20)
Other mistake: When the general passes the clipboard to the President to sign the nuclear release, the clipboard is actually upside-down. (00:55:55)
Other mistake: When Costigan drags a handcuffed Sullivan into the elevator, Costigan slams Sullivan against the wall and his left arm is visible and not in handcuffs. (02:13:05)
Other mistake: Where does the fire in the gas pipes come from? Even though a lot of gas - and thereby pressure - is directed towards the power station, why do they blow up under ground far away from the power station?
Suggested correction: The pressure caused a pipe to crack or similar, and some gas leaked out to where it shouldn't be, and it got ignited. You couldn't count on that happening, though. The idea was probably to have the pipes/valves blow out at the power station and flood it with gas.
This isn't a strong correction, especially as it admits that it likely wouldn't have worked and uses a lot of conjecture.
Other mistake: In the beginning of the movie when Kimberly is shackled to the floor you can see that the padlock isn't locked. She could just take it off and be free.
Other mistake: In the scene where they're loading Tom Cruise's first victim into the trunk, as Max lifts at the arms you can see the "dead" guy holding onto Max's forearms. (00:20:55)
Other mistake: The case of money is in the complete opposite physical orientation when Moss retrieves it from the air duct in room 38. When Llewelyn Moss hides the money in the air duct from room 138, he pushes it to the end of the ductwork with the closet rod and then pushes it to the left with the top of the case and handle going in first and the bottom slightly sticking out. So the top of the case (with the handle) appears to be pointing left in looking at it from 138. When he pulls off the grill in room 38 the next day we can see the top and handle protruding on the right side of the air duct (handle facing left, as he peers into the ductwork). Since we know from the motel room map, that room 38 is directly behind 138, with common rear wall, the top of the case and handle should be facing the right, (from a visual perspective), as you look into the ductwork from room 38 - and it is not.
Other mistake: Several close-ups of the business cards of Patrick Bateman and his associates reveal a misspelling of the word "Acquisitions" (the "c" is missing - not a small error, given that this is the name of their department).
Other mistake: When Seagal is in the factory in Jamaica, a "Jamaican" bad guy jumps up from behind a barrel, you can see that he is in fact white - you can see the make-up line on his neck, and his wig is crooked.
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 Johnny Cage is fighting Scorpion in the forest, after Scorpion unleashes his snake-like spear from his hand but before the camera switches to Johnny, you can see the spear move down and it appears to be coming out of his forearm. Also the hole in Scorpion's hand from the spear is now gone.
Other mistake: In the aerial shots of the semis being driven in the mall parking lot, the zombies are milling about. Notice they have left a path just clear enough for the truck. (01:02:40)
Other mistake: When young Vito Corleone shoots Fanucci in the chest at the doorway to his apartment, in a continuous shot, a wound/blood bursts from Fanucci's white vest. When Fanucci proceeds to tear his vest open seemingly in disbelief he has been shot, there is no entry-wound, blood or hole in his white shirt directly under where the wound appeared in his vest.
Other mistake: In the intense outdoor battle scene at the end, when Bruce kicks a guy in the face three times in a row, one of the extras in the background cracks up laughing.
Other mistake: When Jennifer and Gary are scratching the messages to each other on the painted glass, the glass is painted black on both sides so they wouldn't be able to see each others scratchings as the paint on their side would cover the marks the other was making.
