The Tingler (1959)

After the mute wife of a movie theater owner ‘dies of fright’, pathologist Vincent Price discovers an internal creature crushed her spine because she was unable to scream her fright away. He theorizes everyone has one of these creatures residing within them and names it the Tingler. There is a lot of silly terrorizing when the Tingler that was removed from the woman’s spine escapes its cage. The original run of the film included a couple of gimmicks including buzzers being attached to some seats in the theater to be activated during particularly tense scenes. While it’s unfortunate that that can’t be replicated for home viewing, there is a great scene with bright red blood flowing in an otherwise black and white film that just shines on a newer television.
