@TheRealDelia Aye...my first fright was released before ratings... "Invasion of the Body Snatchers" (1956). Was on my local "Creature Features" show. Shiver me timbers, I had nightmares for years that my family "changed".
Also, Wizard of Oz. The scenes with Dorothy imprisoned with the hourglass and crystal ball scared the heck out of me!
@kay_dub I remember seeing Wizard of Oz when I was 3-4, and being frozen with terror in those scenes.
