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: After the party, a girl with a maroon shirt and grey skirt runs out of the house twice.
Factual error: One of the operetta excerpts shown in the movie is the humorous song "This Helmet I Suppose," during which Princess Ida's three brothers are supposed to remove their armor piece by piece, finding it heavy, hot and awkward. Partly as a result of this, the three are soon afterwards quickly and easily defeated in combat. In the film, however, only Arac, the brother singing the verses (played by Richard Temple (played by Timothy Spall)), removes his armor. The others simply stand still. (This might have made the battle scene end differently if it was shown on screen!)
Other mistake: When Walt makes his first appearance back at the dance club after his stroke, he brings flowers for Tia, but he tells another dancer they are for Daphne, which is the name if the actress playing Tia.
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)
Other mistake: In the scene where Fanny Price is caught in the rain, she drops apples from her basket. When she is collecting them from the ground she puts the apples back in the basket, except sometimes she doesn't actually pick up an apple. Clearly, she only pretends to put apples back.
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.
Continuity mistake: When Helen goes on the job interview, Morgan blows his nose and puts the tissue down in front of him. As the scene continues the tissue moves from the end of his desk to back in front of him a few times.
Revealing mistake: When Louie is driving from the mansion, at several times it is obvious that he is not really driving the car. When the car is going straight ahead, he often turns the wheel, and vice versa. This is most obvious just after Vinnie has died, and Louie is asking "Vin? Hey, Vin, you with me over there?". The car is then going through a 90 degree bend in the road, but Louie does not move the steering wheel at all.
Continuity mistake: When Woody Harrelson and Antonio Banderas are fighting, Antonio's character is knocked down and his cornerman calls him Vince, not Cesar.
Other mistake: When Nicole is on "Wake up Time Zone" talking about Centennial her hair is almost to her shoulders. As you see her watching it in home room, it is much shorter.
Factual error: In a scene in a bar the music playing is Blur's Song 2, which wasn't released until 1998 and a Kula Shaker song which wasn't released until 1996, by which time Nick Leeson was firmly in prison.
Factual error: The song Olga and Lensky sing at the piano was written in the first half of the 20th century, while the events happen about 100 years earlier.
Continuity mistake: The whole premise of the movie is a paradox: The main character's colleague thinks the main character has inherited a fortune, and the colleague wants that money which is why he tries to frame him by making him steal some fake drug money. BUT why would the main character run that risk, agreeing to steal the drug money? If he HAD inherited a fortune, he doesn't need a risky ten thousand bucks now, does he? Surely his friend might work out something was up when his supposedly rich friend agreed to run a risk to earn a comparatively small amount?
Continuity mistake: When Ben Jordan and Stan are walking around the fountain, they walk past a long glass railing. The white sneakers of the cameraman can be seen in the reflection on the glass. You know it's him because he stops walking when they stop and continues walking when they do.
Visible crew/equipment: In the scene where Sean Penn is playing with the big band fronted by the female singer, there is a microphone on a boom visible top center of the frame, when the camera does a pullback to show the whole band at the song's end. (VHS version.)
Factual error: In one scene Alvin is driving over a bridge on the Mississippi. He is going in to Prarie Du Chine but the bridge is in a different town, and he is going from east to west not west to east. The town he is driving into is Lansing, Iowa.
Character mistake: When Amy goes to Virgil's house to apologize, Virgil tells Amy that the tree is exactly 14 steps away. However he then leads her there by taking 17 steps.
