Directed by: Dwight H. Little
Starring: Donald Pleasence, Danielle Harris, Ellie Cornell, George P. Wilbur
Visible crew/equipment: When Loomis looks out the window for Michael, you can clearly see the cameraman's reflection (best seen on the Limited Edition DVD).
Visible crew/equipment: When Dr. Loomis arrives to the gas station the boom mic's shadow is visible on the ground. (00:19:02)
Visible crew/equipment: When the sheriff and the officer are talking after getting the gun from his car, you can see a crew member in the background (doorway).
Other mistake: In the scene where Jamie is in the closet, looking at a photo of her mother (Jamie Lee Curtis). The photo looks exactly like the scene where Laurie is sitting waiting for Annie on the ledge in the original Halloween, which wasn't photographed at the time, it's clearly a still from the movie.
Jack Sayer: You're huntin' it, ain't ya? Yeah, you're huntin' it, all right. Just like me.
Dr. Loomis: What are you hunting, Mr. Sayer?
Jack Sayer: Apocalypse, End of the World, Armageddon. It's always got a face and a name. I've been huntin' the bastard for 30 years, give or take. Come close a time or two. Too damn close! You can't kill damnation, Mister. It don't die like a man dies.
Dr. Loomis: I know that, Mr. Sayer.
Trivia: Series creator John Carpenter actually co-wrote an early draft of the script and even considered directing, but his ideas were dismissed by producers as being "too cerebral" for audiences, and he subsequently dropped out of the project. His script reportedly was more focused on the psychological effect Michael Myers had on the residents of Haddonfield (and possibly inspiring other murders), with Michael only appearing in visions, dreams and possibly as a "spirit."
Answer: Likely because keeping Michael in a maximum security facility was seen as a waste of time/resources given he had been in a coma for years.
