Director John Carpenter was raised in Bowling Green, Kentucky. In one scene, the subtitle on the screen depicts the location as "Smiths Grove, Illinois." Smiths Grove, Kentucky, is a small town of about 600 people 15 miles from Bowling Green. There are many other references to other local towns and landmarks.

Since the movie was actualy 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.

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 eyeholes.

The kids watch the opening of Thing From Another World, The (1951) on TV. Carpenter would later re-make this film himself in 1982 as Thing, The (1982).

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.

According to screenwriter/producer Debra Hill, the character of Laurie Strode was named after John Carpenter's first girlfriend.

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.

Halloween takes place primarily in fictional Haddonfield, Illinois. Haddonfield, NJ is the home town of screenwriter Debra Hill.

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.

When Michael Myers, as a child, walks through the living room with the knife, the clock on the wall reads 9:40, but just 5-7 seconds later, the clock chimes 10 times.

Tommy sees Michael carrying Annie back inside the house. However, when it cuts back to the shot, Michael is carrying Annie the other way.

When Michael breaks into the car at the beginning and steals it, the window is cracked. However, throughout the rest of the movie, it isn't cracked.

In a close up on the phone before Lindsay answers it, someone's shadow moves into the light.

When Bob is carrying Lynda from his van he leaves the passenger door open. Later, when Laurie sees the van as she's going to the Wallace house, the door is shut.

Annie opens her car door without unlocking it because Michael unlocked it and is waiting inside.

It is a bit odd that she didn't even try to unlock it, though perhaps she doesn't always lock her car.

When Michael stabs his sister as a child, you see it from his point of view through the mask. As he is butchering her, he is not looking at her, but in fact he is staring at his own hand. This is presumably part of his sickness.
