Dr. Loomis: I met him, fifteen years ago. I was told there was nothing left. No reason, no conscience, no understanding; even the most rudimentary sense of life or death, good or evil, right or wrong. I met this six-year-old child, with this blind, pale, emotionless face and, the blackest eyes... the DEVIL'S eyes! I spent eight years trying to reach him, and then another seven trying to keep him locked up for I realized what was living behind that boy's eyes was purely and simply... EVIL!
Laurie: Lynda, if this is a joke, I'll kill you!
[Referring to a partially eaten dog.] Sheriff Brackett: A man wouldn't do that. Dr. Loomis: This is not a man.
Tommy: Laurie, what's the bogeyman? Laurie: There's no such thing.
[After Michael falls off the balcony] Laurie: Was that the bogeyman? Dr. Loomis: As a matter of fact... it was!
The opening shot appears to be a single, tracking, point of view shot, but there are actually three cuts. The first when the mask goes on, the second and third after the murder has taken place and the shape is exiting the room, this was done to make the point of view appear to move faster.
