The Tingler

Vincent Price (who else?) stars as Dr. Warren Chapin, a pathologist whose experiments prove the human response to fear is caused by a parasitic creature, a “tingler,” attached to the spine. When the doctor’s friend, a silent movie theater owner, and his wife become entangled with Chapin’s experiment, the tingler threatens to break free to menace the population at large. Filmed in black-and-white with a startling infusion of color, the film was originally released with the gimmick “Percepto,” in which random audience members felt their seats vibrate at key moments.
