Factual error: During the credits, as the house is shown, a paper wasp nest is shown hanging from the eaves. Crawling all over it are honeybees, which do not live in paper nests.
Revealing mistake: In the scene where Stripes is looking in the water at his reflection, his body and the reflection don't quite match up. You can tell by his movements that his reflection is computer generated. (This is verified by the audio commentary.)
Continuity mistake: Towards the end, as Willis and Pollack drive the van, Willis is seen inserting the magazines in two handguns. The next scene shows hims putting the second gun on the center console, it has no magazine in it.
Factual error: During one of the many driving scenes we see many cars on the side streets. At one point you can see a Mercedes-Benz ML SUV parked on a corner. This model SUV was not made until 2000-2001. Since the movie is set in the mid 80's this is impossible.
Revealing mistake: When Dekker follows Richards on a motorbike he drives through a glass door with wooden frame. The class shatters noticeably (about a half second) before the bike even touches the door.
Continuity mistake: The girl is supposed to be bathing in the sea naked, yet when she emerges the camera shot is a little too low and reveals that she is wearing bikini bottoms.
Continuity mistake: Just before Burt gets ready for his record-setting attempt, he wraps some asbestos cloth around his leg to protect it from the hot exhaust pipe. This does not allow him to fit his leg within the cowling of the bike, so he throws it off and puts his leg in without the protective covering. As he inserts his leg into the cowling, you can see that his pants leg is bunched up around his calf, not tucked into the top of his sock, as is Burt's usual procedure. However, a close up of the leg only a few moments later shows the pants leg tucked into the sock, and he could never have done that once he was fully seated in the cowling.
Continuity mistake: In one scene with Dahlia and Ceci sleeping in the same bed, Dahlia is awoken from a bad dream. The kid rolls over and pulls the blankets over her shoulder. The next shot, from the hole in the ceiling, shows the blankets around her waist.
Continuity mistake: When Mr Alfred steps into the dog poo, it is on the front part of his shoe. As he shows this shoe to Preacher, it is now in the middle.
Factual error: The vehicles in the movie have front and back license plates. The state of Florida does not have front plates, only back.
Other mistake: The exact same background shot of a Ventura bomber followed by two single-engine planes flying left to right is used three times during the film, twice at the beginning as they are planning the mission on the beach and then once at the end when the raid is over.
Continuity mistake: The name on Travis' helmet switches between 'Ryer' to 'Travis' several times throughout the movie.
Visible crew/equipment: When Brendan is talking to V.P. Trueman, a boom microphone is seen moving in the reflection of a picture frame to the left of Trueman.
Continuity mistake: After Dan is injured a bandage is placed horizontally above Dan's left eye. In all subsequent shots and scenes the bandage is at an angle.
Continuity mistake: When Steve Martin is talking to Claire Danes (I forget the exact time; she's wearing a tan sweater, I remember), she's sitting on a bed. At one point, she leans forward. The very next shot is of Steve Martin standing in front of a mirror opposite the bed - and in that mirror, Claire Danes is sitting *back*.
Other mistake: In the credits at the end of the film "Editing" is spelled "Edting."
Continuity mistake: When Bob and Robby are eating Mexican food, Robby borrows a bottle of hot sauce from a neighboring table. When he gets done putting the sauce on his food he places the bottle on the right side of the table. The bottle remains there until the end of the conversation. At the very end of the conversation we see that the bottle is now in the center of the table directly between them.
Continuity mistake: When Tim goes to the house and Kate falls off her horse, they go inside. When she leaves you can hear a car engine start. If she rode her horse to the house how did she get her car there?
Other mistake: When Owen first meets Dodger, and asks if its that obvious he's a transfer, she tells him "It's a small school, word travels fast." During a flashback to this scene at the end of the movie she says "word spreads fast," instead.
Factual error: Throughout the movie, the television sets at ABC are airing historically relevant news broadcasts. However, the events are always shown on the same day as key episodes of Dynasty, but completely divorced from the real date of their occurrence. For example, President George Bush is alleged to have been sworn in on the day the finale aired, May 10, 1989, when it really happened in January of that year.
