Laurie: I saw Mr. Riddle in his backyard, he was watching me. Annie: Mr. Riddle was watching you? Laurie! Mr. Riddle is eighty-seven! Laurie: He can still watch. Annie: That's probably all he can do.
Lynda: I can't believe it! We have three new cheers to learn in the morning, I have to get my dress ready and my hair done in the afternoon, the game is at six, and the dance is at eight! I'll be totally wiped out! Laurie: [sarcastically] I don't think you have enough to do tomorrow. Lynda: Totally!
Nurse Chambers: Don't you think it would be better if you referred to "it" as "him"? Dr. Loomis: If you say so. Nurse Chambers: Your compassion's overwhelming, doctor.
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!
[After yelling a smart remark to Michael Myers] Annie: Geez, can't he take a joke? Laurie: You know what, Annie? One of these days you're going to get us all into deep trouble.
Inside Laurie's bedroom there is a poster of a painting by James Ensor (1860-1949). Ensor was a Belgian expressionist painter who used to portray human figures wearing grotesque masks.
Morgan Strode's black Fleetwood (seen in the driveway when he is talking to Laurie early in the movie) belonged to director John Carpenter, while the Phelps Garage truck was owned by the company that catered for the film.
half of the $300,000 budget was spent on the Panavision cameras so the film would have a 2:35:1 scope.
Due to its shoestring budget, the prop department had to use the cheapest mask that they could find in the costume store: a William Shatner mask, from the movie The Devil's Rain. They later spray-painted the face white, teased out the hair, and reshaped the eye holes.
One of the characters is named "Marion Chambers". Marion was the first name of the female protagonist of Psycho, and Chambers was the last name of the sheriff in that movie.
