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.
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)
Continuity mistake: After the two main characters sled down the mountain in that boat, they all fall into the river. In the next shot, they come up from underwater, and the boat miraculously is right-side-up with no water in it.
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)
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: As Corso leaves Quinta Fargas, he barely dodges a speeding car aiming to ram him. Clasping his canvas bag tightly, never dropping it, he presses his back against a large tree. As the camera cuts to a close-up, the bag is suddenly a yard away from him, on the ground.
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.
Continuity mistake: When Zach is talking to Mackenzie about Laney (right after it shows Brock farting on 'The Real World'), there are two shots. In the first, Mackenzie puts cream in her hair, and right away there's another shot but it shows her putting her eye makeup on. She couldn't have finished putting the cream in her hair so fast. (00:14:35)
Continuity mistake: During the scene where Ben is dancing at the gay club, his hands switch from being on his collar to down at his side then back to his collar.
Continuity mistake: When the guy throws the second shovel of dirt on the red haired man, only his lower part of the back gets dirty. Two shots later the dirt is all up his back. (00:45:00)
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.
Continuity mistake: After the car crash, when Ryuuichi gets out of the car, when the shot changes, his coat is opened more and in a different position than the previous shot. Now the sides are curled rather than straight.
Continuity mistake: After the party, a girl with a maroon shirt and grey skirt runs out of the house twice.
Continuity mistake: When they go to the famous writer's hometown, the mayor is taller than the writer then later he is shorter than him.
Continuity mistake: After the fight in the alley scene, two characters start having sex on the front of a car and against a fence. When they are finished, from the back point of view, the woman has her head to the man's right side. When they are showing the opposite shot, the woman has her head to the man's left side. This happens every time they switch views. (00:47:30)
Continuity mistake: When Mrs. Tingle is holding the diary in the classroom, you can see that her nails are short, but later in the movie when her right hand is untied by Jo Lynn, she has long nails.
Continuity mistake: In the shot where Cora and Ellen are in the car going to the beach, the blue car is a left-hand drive, as Cora is driving nearest the camera. However, in the rest of the film, it is a right-hand drive, such as in the shot returning from the beach. Cora is still nearest the camera, but they are travelling in the opposite direction. (00:45:22)
Continuity mistake: In the scene when Nick Chen (Chow Yun-Fat) talks to Jack (Jon Kit Lee) at the NYC Correction, the shot facing Nick shows him grabing Jack's face by the chin. The next shot, facing Jack, shows Nick's hand around Jack's neck. The final shot facing Nick again shows his hand back on the chin. (00:58:50)
Continuity mistake: In the scene where Amelia is driving the truck full of policemen to the scene of the second (Mrs. Rubin) murder, the shot changes a couple of times before it settles looking through the front windscreen at Amelia. Through the rear windscreen of the truck, you can clearly see the highway and all the cars on it behind them. Amelia turns the steering wheel sharply to the left, and you hear the screeching rubber-tyres-on-tarmac noise as if she really had swerved left, but the scene of the highway behind them seen through the rear screen does not alter at all - as if she was just going in a straight line all the way.
