Plot hole: Suzie pulls out some of her teeth with a pair of heavy pliers. This would leave conspicuous tool marks on the teeth that would be visible to the naked eye, let alone under forensic examination. The conclusion would be that Suzie is missing, not dead, and the whole plot would unravel from there.
Other mistake: In the beginning of the song about Augustus Gloop, computer generated Oompa Loompas can be seen running through the Chocolate Room, preparing to sing their song. In the DVD release, some Oompa Loompas can be seen running to places that no real person could possibly stand on. This mistake was later corrected in the Blu-Ray release.
Continuity mistake: Agatha's nightgown strap switches between hanging down on her arm, or being up on her shoulder, normally.
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: In the scene where Page (Jennifer Love Hewitt) follows Jack onto the beach, and she falls over into the mud while clambering through the bushes, Jack finds her on the floor in the mud and helps her up. When she stands in front of him, she's clean, with no mud in sight.
Continuity mistake: When Danny & Debbie are having their New Year's dinner at home, the champagne foam instantly disappears in the very next camera angle after pouring it.
Audio problem: When Focker is going back to Chicago the woman who is typing stops moving her hands for a little while the clicking noise is still going.
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)
Continuity mistake: When Terri is at the party, her blonde wig changes shape and size many times.
Factual error: When the Titanic sinks all six dwarves and Kevin end up in the sea clutching a lifebelt. The water in which the Titanic sank was freezing - that is how most of the casualties died, by freezing, not drowning. In water like that you'd be lucky to stay conscious for more than a few minutes. Despite this none of them show the slightest effect of the cold. Maybe the dwarves have some 'magical' ability to withstand lethal cold, but Kevin doesn't even react to being plunged into freezing cold water. He'd be screaming in pain, but he doesn't even show the slightest sign of discomfort.
Other mistake: Beethoven didn't seem fussed nor resentful of Napoleon being part of the group. Historically he temporarily admired him and wrote the Third Symphony inspired by Napoleon's ideals of Europe's new hope of enlightenment but later despised him after he crowned himself Emperor of France in 1804 and furiously scribbled out his name off the title page of his Third Symphony and named it Eroica which he originally titled it as "Bonaparte Symphony" due to his former admiration of Napoleon.
Other mistake: In the scene where the kids are shooting arrows and the coach gets hit by one, they send a girl to call 911. If you look closely and follow her in the background, after she runs a few yards, she slows down and eventually stops and stands there playing with her hair. Talk about help... (00:57:05)
Factual error: Barry Seal is taken with the guys of the drug-kartel in a yellow helicopter. There is an internet address on the side of the helicopter, half covered by the door, entirely inappropriate for the timeframe of the early 80's. (00:17:20)
Factual error: When Frank knocks out the Umpire and begins to change into his clothes, the umpire is wearing white underwear. All umpires wear black in case the seat of their pants rip so the game can continue.
Revealing mistake: When John picks his wife up at the airport, it's raining. But look at the people around outside, they are in T-shirts, in the sun, and not getting wet. Obviously the rain is being sprayed on the car.
Other mistake: At the end of the movie, when everybody wonders where they are, Gilligan holds up a piece of wood that says Minnow-1, making everybody realise they are back on the island. The name of the boat was known as the S.S. Minnow, and not Minnow-1.
Continuity mistake: When Joaquin enter the bull fighting ring before Manolo's bull fight, Joaquin removes his cape and drops it on the ground. When Joaquin's horse gallops by and Joaquin grabs onto his steed, the cape is missing. (01:35:00)
Character mistake: When Sir informs Kelly that she made the drill team, he says Captain Rigby instead of Major Rigby.
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.
Continuity mistake: When "Emperor" Moe appears in front of Marge, after she and the kids return, the two cartridge belts swung over Moe's shoulders switch from his left over the right, to his right over the left. (01:04:50)
