Factual error: When the bloke's head gets cut off in the beginning by the circular saw blade being thrown, surely there would be more blood, like when his mom got killed under the bed?

Idle Hands (1999)
1 factual error - chronological order
Directed by: Rodman Flender
Starring: Jessica Alba, Vivica A. Fox, Seth Green, Devon Sawa, Elden Henson
Continuity mistake: When Tanya gets pulled into the fan Molly gets sprayed with her blood, and a couple of big red blobs land on her face. But when she runs into the art room seconds later, there is no blood at all on her face, not even smears where she might have tried to wipe it off.
Trivia: The film's release was greatly impacted by the Columbine tragedy. It was unfortunately scheduled to come out only 10 days after the shooting, and as a result many theaters refused to screen it due to it involving teens and violence. Additionally, several politicians (unfairly) criticized the film immediately after the shooting, earning it a lot of bad publicity. The studio quietly canceled the premiere and dumped it in theaters, where it bombed. It later found a cult audience on home video.
Question: How did Anton not remember that he murdered his own parents when he was a killer all along?





Answer: He was either too high, sleepwalking or under the evil hand's control.
