Scariest film I ever saw was Salems Lot with David Soul. Scared the crap out of me it did!! :o :o :o :o :o
Tell ya another movie that scared me to death..."An American Werewolf in London" Especially at the start when they were on the moors. It can get very bleak indeed on the moors in northern England, and the thought of something like that stalking you on one when theres nowhere to run!!!
