The Tingler--what a hoot!

[Hell Hath No Fury]

5. Story about when it was released --

"Ultimately, however, it's all about the gimmick. In House on Haunted Hill, Castle had theaters rig skeletons to glide over the heads of the audience at a certain point in the film. For the climax of The Tingler, where the creature gets loose in a movie theater, Castle had theater owners hire a plant in the audience to faint on cue and get carried out by doctors (not real ones, of course). But that was just the appetizer. For the main course he unleashed "Percepto," a fancy name for a small, motorized vibrator placed under selected theater seats and wired to the projection booth. It was carefully timed to a key scene where the tingler crawls across the projector lens just before the screen goes black and the booming voice of Vincent Price entreats audiences not to panic, but to "Scream - scream for your lives!" Cue Percepto, which goosed the audience into playing along. "In the final count, I think we must have buzzed 20,000,000 behinds," writes Castle in his biography, a possibly inflated number, but then would you expect any different from a born self-promoter?"
