I think it was probably the 1931 "Frankenstein."
The first film I vividly remember being really startled by was "The Land Unknown," which had a scene where a pterodactyl swoops out of the mist and bumps into the main characters' helicopter accidentally (it's the first weird thing that happens, and it comes totally out of nowhere). I remember seeing this on TV when I was a small kid, and being really totally surprised. Whoa!
