Other mistake: A.J. gets dirt on his face although he is covered by an astronaut's suit.
Other mistake: When Will Smith checks into the hotel and his credit cards are invalid, we see that the time is 5:38 and it is daylight outside. The only problem with this is that it is supposed to be around December given all the Christmas decorations. It would be dark then in the Baltimore, not soaked with daylight.
Other mistake: When Ray shoots Kelly twice in the chest, and then himself once in the arm, all three shots are heard within a few seconds. However, in the flashback at the end, Ray shoots himself about ten seconds after.
Other mistake: When Tiff picks up Chucky to throw him into the crib, you can tell that the Chucky doll is inactive and not on or alive. (00:21:20)
Other mistake: When Daniel Baldwin carjacks the guy at the gas station (director Frank Darabont in a cameo) we can clearly see that his car is a Cadillac. However, in the end credits he is listed as "Man with Buick."
Other mistake: When the main characters are in the motel and they hear the moth flying outside the window, Stu, the creepy deputy with the glasses, picks up a shot gun and racks a round into the chamber. In the next shot of all of people firing at the moth through the window, Stu is now holding his revolver and fires with it. When he runs of out ammo with the revolver he picks up the shotgun again and before firing racks the pump again. Since he already did that the gun should have ejected the unfired shell that was already in the chamber from earlier, but no shell is ejected.
Other mistake: At the taxi cab chase at the end, you can notice when the car is a real one and when it's CGI. Note how the real car has scratches and other things on the front of it, but the CGI car, if you look closely, has almost no imperfections, and even if it does have some, it doesn't match the real car one bit. You can see these things when the car drives off his mouth or when you see Godzilla running behind.
Other mistake: During the rigged card game, the angle at which the hidden camera is shown would not have supplied a picture with the view from behind Eddy's shoulder, as is shown on the screen.
Other mistake: After they kill the alien/teacher and leave the school they pass one girl in a blue/green tee-shirt with a waterbottle. Just one scene later you see this girl again under a tree, suddenly in front of them.
Other mistake: Frank visits Walenski just before the tuning, but the clock in his house says it is 1 o'clock. (00:27:17)
Other mistake: Crews is talking to his wife by telephone and says he is in North Carolina. The signage shows he is at the I-85/I-26 interchange in Spartanburg, South Carolina.
Other mistake: Half way into the film when the neighbors are mowing their lawn in synchronization, if you look closely the nearest two of the electric lawn mowers are not actually plugged in. You can see extension cord plugs just dangling off of the handle bars.
Other mistake: The killer leaves the corpses of the Dean and Parker where they are and walks away, but they later appear in the room at Stanley Hall.
Suggested correction: That is because the killer is moving around the bodies. Just like when Damon is killed. His body is not where it was left when Alicia Witt comes back with the cops.
Other mistake: When the arms deal goes wrong by the river in Paris, Larry drives the Audi flat out straight into the tunnel where the bad guys BMW is parked right in the middle, leaving little space to get another car through. Even if he could squeeze the Audi past the other car, there were dead bodies either side that he would have to drive over, as well as crashing into the doors that were left open. This would have done some damage to the Audi at the speed he was going.
Other mistake: When Karla and Ty are in the jacuzzi, the "Bob Marley" guy shows up and says they can't be there because it's after midnight. At the same time, the fisherman is killing the hotel's maid who is knocking on doors to clean the rooms. Why in the world does the cleaning lady do the housekeeping after midnight?
Other mistake: When Data discovers the holoship in the lake he reduces the amount of water in the lake significantly (The ship is now clearly visible, standing out several meters). But even so the banks and the landing stage are still in their correct position. If the surface level had been reduced the landing stage should have been standing out of the water, too.
Other mistake: When Wesley Snipes is being questioned about the double homicide in New York, the detective says that it occurred in December. When Tommy Lee Jones is viewing the tape of the double homicide from the UN garage security cameras, the date from the video tape clearly says "12 Jan".
Other mistake: When Jackie is falling through the trees at the beginning, you can easily tell he is on strings because he would hit the branches with a lot more force than he does, and also wobbles in certain ways which would be impossible to do in this situation.
Other mistake: Phillip Baker Hall sends Chris Tucker to meet with the FBI immediately after he tells the agent on the phone that he will be sending someone over to them right away. Chris is told by the FBI guy that Jackie Chan's plane arrives in one hour. After Chris picks up Jackie from the airport, he calls his boss to vent his concern. This is supposedly the same day, but both Phillip and Elizabeth Pena are wearing different outfits.
Other mistake: When Jude Law and the police officer are walking to the officer's car, Jude asks the officer if he is married. Why is it he asks this? Earlier on in the film, at the police station, the officer told Jude that his wife gave him that very same necklace.
