Famous as the film in which producer/director William Castle wired theatre seats to give customers mild electric jolts at key points, this offbeat chiller stars Vincent Price as a doctor who discovers that intense fear causes an insect-like creature to grow inside a person's spine, and only screaming can kill it. His theory, however, really gets put to the test when a "tingler" runs amok in a movie theater! With Darryl Hickman, Philip Coolidge, Judith Evelyn. 82 min. Widescreen (Enhanced); Soundtracks: English Dolby Digital mono, Spanish Dolby Digital mono; Subtitles: English, Chinese, Korean, Portuguese, Spanish, Thai; featurette; drive-in sequence; biographies.
