Other mistake: When Walker and Michelle fall down the steps at Dede's apartment, Walker lights a match to show Michelle the matchbook. The light from the match flickers on their faces but if you watch closely you can see the match go out as soon as Walker strikes it. (00:54:45)
Other mistake: In one shot, during the lynching, the noose comes undone from the character's neck while he is hanging.
Other mistake: During the first volley from the laser satellite, Kaneda is less than 30 meters from Tetsuo. A massive explosion and fireball hundreds of meters wide is shown within seconds, but somehow, Kaneda survives despite close proximity to the blast. (01:36:00)
Other mistake: When Eddie Valiant gets thrown out of the Ink and Paint Club, he is already starting to go through the air as the gorilla moves his hands to throw him. (00:21:20)
Other mistake: Right after Heather Duke and Heather McNamara drop in on Veronica and Betty Finn playing croquet, Veronica talks to her parents about the suicides. She still has a croquet mallet in her hand, so little time can have passed. Heather Duke rushes in with a shopping bag, and tells Veronica that while at the mall they heard about Martha Dumptruck's suicide attempt. But Heather Duke had just left Veronica's house - there wasn't enough time for these events to happen.
Other mistake: At the beginning of the movie, Ginevra is reading the magazine but is interrupted by the outbreak of a thunderstorm. There is no rain at all, though, just the sound effect of thunder, with the car already wet at the beginning of the take to try to establish the illusion. (00:00:40)
Other mistake: The 3rd movie takes place 5 years after the original, since Kristen is still in high school this one can't take place too long after that. How does Nancy's house get so run down in only 5 or 6 years?
Other mistake: Amazing that nobody sees the hooker's dangling body before that boat tour which looks like it's around nine, plenty of time for somebody else to notice her.
