Continuity: When John and Maggie are at the old school, there is a teacher talking to a class which isn't really there. The teacher stands by the left side of the blackboard, which has large crosses drawn on it, in rows. It cuts to a closeup and the crosses are now smaller and more scattered.

Continuity: When the doctor is talking to John Doe, you see her grabbing his arm. Also there is a man in a green shirt passing by them. Then it cuts and she grabs his arm again. The man in the green shirt is gone but now there is woman in black where the man should be.

Continuity: At the start of the film on the plane, there is a woman sitting next to John Doe whose glasses go from being on her face, to then hanging down on straps around her neck, then back on her face between shots, just before she flies out the plane roof.

Revealing: When John tries to stop the van while Maggie is driving, because he sees the small girl in the road, as the van screeches around the road, you can see the road is covered in tyremarks from previous takes.

Continuity: John opens the window to find out the house is falling, and a large object goes flying through the window next to the bed, smashing out all the glass and all the wooden frames. Seconds later all the wooden frames are now repaired, however all the glass is still missing.

Continuity: When Freddy is controlling Spencer in the video game you see from Freddy's view that his legs are crossed on the table. When it cuts to in front of Freddy he has one foot only on the table.

Revealing: Right before the John Doe gets pulled through the roof of the van by the dream parachute, you can see the premade cuts overhead for the stunt person to be pulled through.

Revealing: In the blackboard scene. After Freddy stretches the blackboard vertically, it switches to a closeup shot of him peering out from the side of the board. If you look closely at his glove, you'll see clear plastic caps on the tips of the knives. You'll also see them when he scrapes the board with his pinky and the final time he runs his hand across the board.
