Continuity mistake: Right after Evelyn gets electroshocked, Blackburn takes off her mouth guard and a pool of blood leaks around her lips and down the side of her cheeks. In the next shot, there is a little bit on her lips, and a lot down the side of her cheeks, and several shots later she is seen with only a little dribble down her cheeks and none on her lips.
Continuity mistake: At the end of the movie when Michael chases the delivery truck in a red Ford Contour, he crashes into a bus and the car spins several times. If you watch closely you can see that after the crash the left headlight is very badly damaged and the right one is missing, but the next scene shows the car almost undamaged.

Continuity mistake: After the priest writes down 666 on a piece of paper, he holds it upside down to reveal that it is 999. When we cut back to him a few seconds later, the numbers look completely different. (01:05:40)
Continuity mistake: When Molly ties Tanya's whip around a bar to let herself down from the air duct, you can see as she slides down that the whip is knotted at intervals. But a few moments later, when the severed hand draws the whip back up, you can see that there are no knots in it.

Continuity mistake: At the end when they "fly" out the ship you can see there are still high waves from the storm, but in the long shot of the ship exploding, the surrounding sea is a lot calmer.

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: 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.
