The film "The Lost Boys" was released in 1987 and has since become a cult classic. The film was about two brother Sam (Corey Haim) and Michael (Jason Patric) who moved to Santa Clara, CA with their mother after their parents divorce. The two brothers soon realize that life in Santa Clara is a bit different, vampires are all the rage.
The whole family some how gets tied into the local vampire gang. Sam starts hanging around with two vampire slayers, Michael falls in love with a "half vampire" woman and he almost becomes a vampire himself. And on top of that their mother, is unknowingly dating the head vampire. A must see film.
