One of the ones that sticks in my mind is a Vincent Price movie.
The Last Man on Earth. There's a virus that's turned everyone into vampires except Vincent Price. It's in black and white.
I loved The Tingler! Especially when everyone was sitting in the theater and the lights went out!
The Tingler was awesome, ha ha ha! I'd forgotten all about it. Remember when it got in the movie theater and an image showed up on the movie screen -- it looked like a sea-animal-big-centipede combination.
