DON'T ANSWER THE PHONE (1980)

This was originally supposed to be a film about the Hollywood Hillside Strangler so while technically a slasher flick it features a killer/rapist who strangles his victims so it's not very bloody in the standard slash and kill tradition. It's also from 1980 before the strict template was set that almost every film in this sub-genre followed so for that reason I find it interesting. It's also memorable for the crazy-ass performance of our killer played by Nicholas Worth who went on to play small roles in a bunch of movies and TV shows. I'll always remember his fantastic role as that fat guy who arm-wrestles Mama on that stupid Mama's Family show. In this flick he has some great rants while communicating with his dead dad. Also he calls into a radio show and talks with a Spanish accent. Porky from PORKY'S shows up as a sleazy porn publisher in a couple of great scenes and there's some equally sleazy pimp and whore action in a standout scene. Plus you get lots of boobs although they're all on girls that get snuffed so if you don't mind that check it out even if it may not be the best example of a slasher you'll ever see.
