The Little Shop of Horrors is a 1960 American horror comedy film directed by Roger Corman. Written by Charles B. Griffith, the film is a farce about a florist’s assistant who cultivates a plant that feeds on human blood. The film stars Jonathan Haze, Jackie Joseph, Mel Welles, and Dick Miller, who had all worked for Corman on previous films. Produced under the title The Passionate People Eater, the film employs an original style of humor, combining dark comedy with farce and incorporating Jewish humor and elements of spoof.
