Halloween (1978)

Continuity: In the scene when Michael is carrying Annie's body into the house her head is on the left side of his body. After they show the boy looking out the window they cut back to Michael and suddenly Annie's head is on the right side of his body.

Revealing: Even though the story is set in Haddonfield IL, all of the cars have California license plates.

Visible crew/equipment: There is a scene where Michael Myers is hiding behind a hedge bush and Laurie and her friend go to investigate. Laurie turns around and talks and you see cigarette smoke go by the camera (John Carpenter admitted on the commentary track that he was smoking a little to close to the camera that day).

Michael Myers' mask is a Captain Kirk mask painted white with ruffled hair.

Up until The Blair Witch Project (1999), Halloween was the highest grossing independent movie ever made. It was made with a tiny budget of $325,000, but made $47,000,000 at the box office.

When they were shooting the scenes for the start of the film (all the ones seen from Michael's POV) they couldn't get the 6-year old child actor until the last day so the movie's producer, Debra Hill, volunteered to be Michael for any scenes where his hands come into view. This is why the nails on young Michael's hands look so well manicured and varnished.
