Other mistake: When Zach is watching Laney at the show, there are two shots where Laney, Mitch and the little people say, "Be silent, be still". In the first, Mitch's legs are far apart and on the ground, and in the second shot his legs are very close together, with no time to move. (00:22:35)
Continuity mistake: Near the end, when Betsy and Arlene are cutting the stars out of the American flag, one shot is a close up of their hands - they have almost finished when the camera cuts to a wider shot as they question the legality of the activity. When they resume cutting their scissors are further back then they were in the close up ie. they are cutting where they have supposedly already cut.
Continuity mistake: Sarah Michelle Gellar is preparing for a date and switching purses in her bedroom. The shots are going between her and whoever she is talking to. One of the purses disappears then magically reappears.
Continuity mistake: Warren is shown ripping the locket from Amy's neck after he shoots her, yet when he throws the locket on the seat of the car, the clasp is not broken, as if Warren had removed it properly.
Revealing mistake: When Yoichi's mother is killed, the blood coming from her body is very obviously just colored water, as it is too bright and too thin to really look like blood.
Continuity mistake: When Beowulf is rescuing Pendra, at the end of the fight he is holding is sword over one of the men. In some shots it is clean, in others it has blood on it. (00:08:00)
Factual error: As Pellew and Hornblower return to the Indefatigable, they go aboard a ship's launch. In the Royal Navy, when boarding a small boat, the senior officer always boards last, so he can disembark first. Captain Pellew boards before Lieutenant Hornblower.
Factual error: When Ryuuichi shoots the man in the car with the shotgun, you see a single large glop of blood hit the windshield. From this range, however, the man's head would splatter all over, not just in the one direction as shown in the movie.
Continuity mistake: When singing the song about what they would do if the monster came to their room in the night, Simon puts on Alvin's duvet/blanket as a cape. It then shows an imagination sequence where the blanket is a correctly sized cape to fit him. When it returns to the real world, the 'cape' is the size of his imaginary cape, nowhere near the size of the bed.
Revealing mistake: In several scenes (e.g. in the deli & in the tunnel, at the end) the ice cubes used to cool Elvis down are obviously not real ice.
Continuity mistake: Sean Bean is listening to the radio while he is in the shower - in the next scene he is exiting the bathroom with towels on so there is a time gap between the two scenes. However the monologue of the radio plays on through both scenes without any interruption. Actually, when he leaves the bathroom for the bedroom, the radio volume decreases, even though the radio is in the bedroom (he subsequently reaches over to turn it off). (00:01:40)
Deliberate mistake: This is being made as more of a movie than a documentary as it is using actors to portray Jesse Ventura and other wrestlers (like The Superstar Billy Graham). Needless to say because TBS is making the film, WCW Monday Nitro and Thunder were used to film the matches. As a result the rings contain logos for those events (neither the events nor the logos existed in Ventura's days as a wrestler). In addition the ring announcer is using a cordless microphone which was definitely not in use when Ventura fought the Superstar.
Continuity mistake: When Pépé remembers the moment when the Old Man told him how to become wealthy, the Old Man is exactly as old as when he meets Garriss decades later, shortly before he dies. (00:48:25)
Visible crew/equipment: When the firetruck arrives you can see the entire crew reflected in the side of the truck.
Continuity mistake: At the very beginning of the film we see the Seminar Leader start to write eXistenZ on the board. We see him write the letter 'e', but then the camera changes and he starts to write the letter 'X'. Notice that the letter 'e' has changed from how he originally wrote it. Then when he finishes writing eXistanZ the camera switches position again and the writing has all changed the look again. Most noticeable by the crossing of the letter 't'. As we saw him write it, then cross portion was much higher than in the wider shot.
Continuity mistake: When Ed and Sherry get back together, you see a few shots of Rita, Sherry's roommate, watching them on TV and she's wearing a red top. Then about two minutes later, when Ed starts the contest you see another shot of her but she's now wearing different clothes, green dungarees and a grey jacket. Then later on just before Edtv is cut off, she's wearing different clothes again. Why would she change three times in one day? (01:43:05 - 01:47:15)
Continuity mistake: In the scene where Juliette Lewis is at her downstair's neighbour door, knocking on it, we see the hall empty, but right after, it's full of the trash bags.
Factual error: Whenever one or more of the mutated, super venomous snakes attack someone, you can hear a rattling sound because they evolved from rattle snakes. However, it frequently shows the tips of the snakes tails, and they are completely bare. How can they constantly make that noise if they don't have rattles?
Continuity mistake: After the party, a girl with a maroon shirt and grey skirt runs out of the house twice.
Continuity mistake: When Hugh Grant is about to propose in the restaurant near the start, his girlfriend's hair keeps moving from in front of her ear to behind and back again with each change of shot.
