Factual error: No actor is going to secure a recurring speaking role in a soap opera unless a comprehensive insurance policy has been secured. (This applies to feature films, too.) This will inevitably involve a medical examination. Mr Dorsey's plans are going to become dreadfully unstuck the minute he drops his y-fronts in the doctor's surgery. (No, he can't find a compliant or bribeable doctor - the insurance company will always use their own people.)
Continuity mistake: When the twins are singing about Brad for the talent show, and Michael was playing the piano (you have to listen and watch), his hands are suppose to go across the keys but he is still doing the fake up-and-down-hand-move.
Other mistake: When McCroskey gets the information about Joe Seluchi, he's told that Seluchi purchased life insurance and was impotent. McCroskey informs Ted about Seluchi and the bomb he's carrying but nothing else. When Ted confronts Seluchi, he mentions both the insurance and the impotence.
Continuity mistake: In one scene, Nick Nolte is driving Eddie Murphy around in a convertible. First you see Murphy in handcuffs, then no cuffs, he's got one arm on the back of the seat, and then back with the handcuffs on.
Continuity mistake: When Brad Hamilton is pouring the coffee in the machine at the Mi-T-Mart, there is a clock on the wall next to the battery display, but when the guy comes in to rob the place, the clock is gone and there is a Hostess Fruit Pie poster there now. (01:23:00)
Continuity mistake: Coach Brakett (Boyd Gaines) finally convinces the young gym teacher, Honeywell (Kim Cattrall), to go with him to the boys' locker room. Once they are up there he disrobes her and gets on top of her. When they cut to a close-up, you can tell that he has longer hair than just two seconds before. (00:58:40 - 00:59:40)
Revealing mistake: In the scene where Chuck finds Bill in the morgue vault listening to the recording of Chuck telling him to shut up, take note of Bill's thumb on the rewind button of the tape recorder. You can hear the tape recorder rewinding to replay the words, "Chuck to remind Bill to SHUT UP" multiple times but Bill's thumb does not move at all until he turns the recorder off. (00:30:00)
Continuity mistake: When De Niro's character gets in the limousine with Lewis' character he has a hurt hand. He wraps it with a handkerchief. As the scene progresses the handkerchief disappears and reappears depending on the camera angle. (00:07:15)
Visible crew/equipment: Near the end of the movie, Michael McKeane is walking towards the camera, and the overhead mic pops down a couple of times.
Other mistake: When the Aggies are in the locker room after the football game, they are all getting undressed and showering. This is happening right after the game yet none of them have a spot of dirt on their nice white uniform pants. (00:59:50)
Visible crew/equipment: When the PE coach arrives home, and walks inside, as she bends down to put her bag on the floor, you can see some equipment moving in the glass frame of the photo above her, on the shelf. (00:18:35)
Continuity mistake: When Jen Moo ambushes Fukoda in his house, he kicks part of the waterwheel's gear against him, jamming it solid and pushing him through the wheel into the river. But in subsequent scenes, the wheel turns again, and it is completely undamaged.
Revealing mistake: When the bugs crawl out of E.G. Marshall's mouth, it is obviously a dummy.
Audio problem: In the scene where Jack Brown (Richard Pryor) is talking to Eric about "Earning a friend" there is a problem with the lip-sync when the camera changes to an overshoulder of Richard. His mouth is moving but the spoken text is different. This occurs repeatedly during that scene.
Continuity mistake: Closeau is at his desk preparing to light his pipe. The Pipe is in his mouth as he lights the match, the camera angle changes and now it is out of his mouth in his left hand as the camera zooms in, he puts it back in his mouth to light.
Factual error: Kathleen Quinlan is named Janet Dunn, but when Gene Wilder looks at the newspaper and sees the headline about her murder, it falsely says her name is Janet Stone.
Factual error: When Gary unscrews the top to the nozzle of the front tire of Karen's bike it automatically starts to make a loud hissing sound as if it's losing air rapidly. This wouldn't happen as although the tire would lose air over time it wouldn't make that loud hissing sound unless there was a rip or tear in the rubber. (00:21:35)
Visible crew/equipment: When Fenwick and Boogie are driving in the country watching the woman on horseback, the window on Fenwick's side of the car goes up and down several times in different shots. When the window is up, the cameraman can be clearly seen reflected in the glass.
Continuity mistake: When Burt Reynolds and Goldie Hawn are left alone to write the final scene to a movie, Goldie says she needs air, so Burt takes a trash can and breaks out a window. In the next shot, more of the window is broken out than was shown previously.
Continuity mistake: In the scene where Victoria is watching man eat a cream cake, the man has cream on his nose but in a different shot he has none.
