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!
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: When the fish tank has been cleaned by the newly installed laser fish cleaner, the machine states that the water temperature is '82°.' In Australia the Celsius scale is used; therefore, it should be about '28°.' Australia is 100% metric and has been since 1974! Nobody in Australia - nobody, anywhere, any time since 1974, uses imperial measures. There is absolutely no question of the dentist having an imperial thermometer or expressing himself in° Fahrenheit. It is actually illegal to import or sell any instrument using 'Imperial' scales. You couldn't buy a Fahrenheit thermometer if you tried. (01:14:30)
Plot hole: When Sarah Paulsen pulls the necklace out of the water, the necklace clasp is obviously closed. Since the circumference of the necklace is too small to fit over the top of Anne Hathaway's head, why would anyone believe that it fell off her when she was running to the bathroom? The only way that could have happened is if the clasp (which we were earlier told can only be opened by a magnet) had opened. The trained security guards wouldn't have suspected something wasn't right about a closed necklace falling off over of her? They were following her. They saw that at no point did she lower her head on her way to the bathroom for the necklace to fall off over her head to begin with. It also could not have fallen off her when she was vomiting into the toilet in the bathroom since the clasp was closed. (01:18:25)
Revealing mistake: On Billy's first day of school when he is outside waiting for the bus and it just passes him you hear the noise of kids on a bus, but when it passes no one is in it.
Other mistake: In the beginning of the movie, when you first see Mary-Kate (aka Mel) and Ashley (aka Ally), Mary-Kate walks off without ever closing her locker.
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: During the interview, while sitting, his striped pants are unzipped for a few cuts, then they are zipped in later shots.
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.
Plot hole: At the end of the film Mardukas reveals that he has been wearing a body belt packed with cash - "in the neighbourhood of three hundred thousand dollars" - ever since Jack detained him in New York. Are we to assume that Jack Walsh, an experienced, hard-bitten ex-police officer, now a bounty hunter who routinely chases down violent and armed bail absconders who would kill him without a second thought, didn't even perform a perfunctory search of Mardukas when he detained him? This man used to work for the Mafia! What if he was carrying a weapon? A body belt with three hundred one thousand dollar bills in it would be uncovered by even the most casual pat down.
