Continuity mistake: After Nick becomes a hero, he wears a cast on his right arm. However, when he and Kate go to dinner with Kate's boss, Nick's cast mysteriously disappears for one shot. They are sitting at the table at the beginning of the dinner and Nick picks up a glass with his right hand, with no cast. The next time you see Nick, he has a cast on his right arm again.
Continuity mistake: The first scene with Murray Babitch driving across the George Washington Bridge from New York to New Jersey was actually filmed going the other direction. When driving from New York to New Jersey on the lower level of the bridge you enter a black tunnel first, and exit through a yellow tiled tunnel. The scene in the film starts in the yellow tiled tunnel - New Jersey to New York direction.
Visible crew/equipment: When Robinsons Crusoe's boat breaks lose, you see a shot of a beach, and in the lower left corner there is some kind of information board. (00:59:50)

Continuity mistake: In the scene where McHale rides his motorcycle out of the boat, the machine gun on the aft deck is off center (so he can drive past it). The rest of the time it's on the centerline of the boat.
Continuity mistake: Ripley kills the alien in the corridor after it has killed the first member of the Betty crew but there is no melting of decks or bulkheads from the creature's acidic blood. Also, the Betty crew seem unaffected by all the acid. (00:46:00)
Continuity mistake: When Jennifer Love Hewitt is talking to herself as she drives to pick up Will Freidle, her hair is up neatly in a butterfly clip. Then in the next shot, her hair is down. Finally, in the last shot her hair is up again.
Continuity mistake: When the Lady Chablis "crashes" the debutante ball - she leaves her purse on the table while she dances, and then forgets to retrieve it before she leaves. (01:44:35 - 02:07:50)
Continuity mistake: When the men enter the cyclops' cave, Odysseus crouches down and says "They keep sheep in this cave with them". Between shots his arm goes from being at a 90 degree angle to being at a 45 degree angle.

Revealing mistake: There is one scene where Alicia Silverstone is being taken away, and in the window, in the background, you can see a metro train with the letters on the side stating BC Transit and a picture of the British Columbia flag. Yet, the whole movie supposedly takes place in Washington state.
Factual error: Towards the middle of the film,Pacino and Depp are walking downtown, there is alot of traffic and some of the cars are "post 1978" model . One in particular caught my eye, which was a mid-80's Ford Taurus (even the model of the car didn't exist in 1978).
Factual error: Near the beginning, when the Russian Delta-class sub is locking US cities as potential targets for nuclear missiles, Boston is one of the cities that appears in Russian on the computer screen. However, the way it is written is wrong (it starts with B, the Cyrillic character for V not B, so it appears as Voston).
Revealing mistake: In Dirk's first sex scene with Amber they are both supposed to be naked except for their shoes. At the end of the scene Amber sits up on the table on which they had sex as a female stage hand wraps her in a robe, and you can see she is wearing black panties.
Continuity mistake: The pile of clothes that falls onto the remote control car changes between shots. The hamper turns over as well. (00:37:35)
Continuity mistake: When Billy Connolly and his on screen brother have just been for a swim, they are drying themselves off on shore. Just to the left of his brother you can clearly see someone windsurfing in the background - not bad for the late 19th century.
Continuity mistake: At the university in the beginning, the blackboard on the wall changes position in every shot - once it's pushed up, next shot it's at the bottom. Several times. (00:04:10)
