I've mentioned most of these before but films that scared me as a kid...
Sssssss (1973) silly film about Dirk Benedict turning into a giant snake, still a bit creepy though.
It's Alive (1974) silly film about killer babies, it's also still pretty creepy.
Salem's Lot (1979) more creepy kiRAB, still scares the bejessus out of me.
Dead of Night (1977) even more creepy kiRAB! Well, just the one, 'Bobby'. revisited it on youtube recently, yep, still had me nearly wetting the bed 30 years after I'd first seen it.
An American Werewolf in London one of my all time favourite films, scared me senseless as a kid, still can't look at the dream sequence of him lying in bed. Sister's boyfriend once set it as my screensaver...ha, ha very funny.


Someone mentioned something about a scary doll film from the 70's. Was this the film about a possessed porcelain doll that came to life and killed people? If so, yep, scared me too. Saw it a few years ago, silly film but creepy.
Not seen the film, but then I guess many on here haven't either but used to have a book with a photo of Lon Chaney in from London After Midnight. Off the scales in regarRAB to creepyness.
