[After Michael falls off the balcony] Laurie: Was that the bogeyman? Dr. Loomis: As a matter of fact... it was!
[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.
[Referring to a partially eaten dog.] Sheriff Brackett: A man wouldn't do that. Dr. Loomis: This is not a man.
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.
Tommy: Laurie, what's the bogeyman? Laurie: There's no such thing.
Halloween was shot in 21 days in the spring of 1978. Made on a budget of $300,000, it became the highest-grossing independent movie ever made at that time.
The performance of Halloween's musical score is credited to "The Bowling Green Philharmonic." There is no Philharmonic in Bowling Green. The "orchestra" is actually John Carpenter and assorted musical friends.
Since the movie was actually shot in spring, the crew had to buy paper leaves from a decorator and paint them in the desired autumn colors, then scatter them in the filming locations. To save money, after a scene was filmed, the leaves were collected and reused.
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.
