John Carpenters ~The Thing~ With Kurt Russel...the aliens taking the shapes of other living things....the dog's face peeling apart like a flower...Ewwwwwwwwww, So damn creepy!!!!!!!!!!!!!!!!
Oh, and the first ~Alien~ movie was pretty scary. I've seen all the Hitchcock movies everyone has mentioned. Maybe I'm not old enough or just too de-sensitized, but they are not very scary to me.
