The Tingler (1959)
The Tingler is a 1959 horror-thriller film by American producer/director William Castle. It is the third of five collaborations with writer Robb White and stars Vincent Price, Darryl Hickman, Patricia Cutts, Pamela Lincoln, Philip Coolidge and Judith Evelyn. The film tells the story of a scientist who discovers a parasite in human beings, called a "Tingler", which feeds on fear. The creature earned its name by making the spine of its host "tingle" when the host is frightened. In line with other Castle horror films, including the 1958 Macabre and 1959 House on Haunted Hill, Castle used gimmicks to sell the film. Most well known for The Tingler was called "Percepto!", vibrating devices in some theater chairs which activated with the onscreen action. The Tingler received mixed reviews and is generally considered a camp cult classic.
