The Little Shop of Horrors is a 1960 American black comedy horror film directed by Roger Corman. Written by Charles B. Griffith, the film is a farce about an inadequate florist's assistant who cultivates a plant that feeds on human flesh and blood. The film's concept is thought to be based on a 1932 story called "Green Thoughts", by John Collier, about a man-eating plant. However, Dennis McDougal in Jack Nicholson's biography suggests that Charles B. Griffith may have been influenced by Arthur C. Clarke's sci-fi short story, "The Reluctant Orchid. The film stars Jonathan Haze, Jackie Joseph, Mel Welles and Dick Miller, all of whom had worked for Corman on previous films. Produced under the title The Passionate People Eater, the film employs an original style of humor, combining black comedy with farce and incorporating Jewish humor and elements of spoof. The Little Shop of Horrors was shot on a budget of $30,000 in two days utilizing sets that had been left standing from A Bucket of Blood.
