Continuity mistake: During the beginning of the movie, when Laurie is talking to the police officer, the sun is shining bright as if it is a perfect day, then when Laurie walks to her house, the trees look as if it has just quit raining.

Halloween (1978)
Ending / spoiler
Directed by: John Carpenter
Starring: Jamie Lee Curtis, Donald Pleasence, P.J. Soles, Charles Cyphers, Nancy Kyes
Trivia: 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.
Question: Why was Michael killing people? There was no mention of his history, or what made him the way he was.
Answer: The movie doesn't require a back story, although subsequent sequels, and the Rob Zombie remake address your questions. Then again, what makes any serial killer kill? The topic has been studied by psychologists for decades. Often serial killers lead normal lives, at least in public.





Answer: The only answer given in this film is that Myers is purely and simply evil. He's just doing it because he's compelled to, and doesn't seem to have any trace of humanity left inside of him. Future sequels attempted to give an explanation, but to varying degrees of success. But as far as this original film is concerned - he's just pure evil.
