Continuity mistake: When Adam Banks is playing in one of the games, he scores a goal and his teammates on the bench stand up and cheer when he scores. Problem is, Adam Banks is on the bench too.
Revealing mistake: Near the middle of the movie Samantha Mathis is walking across the high school campus. The name of the high school in the movie is "Hubert Humphrey High School, " but behind her, above the library door, a sign says "Saugus High School Library". Shows better in 4.3 aspect. (00:31:45)
Revealing mistake: When the boys drive the car over the gap in the bridge, look at the side view that shows the main jump, watch the front wheels, they lift up in the air unnaturally before the car leaves the ramp. (00:34:00)
Continuity mistake: Towards the end when Debbie and Danny get into a fight around 5am at their apartment, Debbie packs some things and goes over to Joan's apartment to mull it over with her. While they're talking with Joan in her robe, Joan's hair goes from being up in a hairband (not even visible out of the hairband) to her hair being down and styled with no hairband at all and then back to up to not visible in the hairband again.
Continuity mistake: During the interview, while sitting, his striped pants are unzipped for a few cuts, then they are zipped in later shots.
Plot hole: How could Jane not be aware that Tom had only used one camera for the date rape interview, recording his fake tears later? That's the way things are done on television news shows and as an experienced, hard-bitten television producer she could not possibly be unaware of that. The reporter always records his or her reaction shots (called 'noddies') after the interviewee has left. Shooting with two cameras would involve two crews, two lighting rigs, a vision switcher and so on and so on and a straightforward interview simply would not justify such a complex and expensive set up.
Factual error: The whole Bowfinger scenario is impossible. They are using a 35mm Panavision cine camera which cannot be focused through the lens; it needs precise measurements on the set in order to be properly in register. Then there are the light readings required to ensure proper exposure. Wouldn't Kit Ramsay notice the man with the light meter, or the one with the tape recorder? Both measurements would have to be done with him or an identically dressed and made up stand-in (a "lighting double") on the spot. Then there is the sound. Any sound recordist worth his salary will have the microphone within centimetres of his subject, and he'll have a boom operator keeping in there. We don't even see a microphone in use! Please don't tell me this is based on the clandestine filming of Mary Pickford during her Russian visit: that was done with old black and white film which has very wide tolerance to exposure and most of all it was silent, and she was aware of the camera crew, she just thought they were news crews. (And the results were rubbish anyway).
Factual error: Then, as now, every recruit reporting to boot camp would be tested for illegal drugs, first by a urine test and then by a broad spectrum blood test in the case of a positive result. There is no reason for Elmo to try to hide his stash when the recruits are told they are to be tested - he is going to come up positive anyway. He may as well just say he has changed his mind and walk away. He is entitled to do that any time up to ten days after he signed on, and it happened a lot in real life!
Revealing mistake: When Cindy and Buddy get trapped inside the cold chamber, she starts rubbing him to a point that it becomes masturbation. But when she's sitting on his legs doing the thing, in one side shot you can clearly see she is not holding his privates and her hand is just going up and down, closed but empty. (00:58:05)
Revealing mistake: The kid in the wheelchair is playing a Game Gear with no game in it.
