When asked where Seymour got the plant, he replies that the seeds were obtained by a Japanese gardener who found the bulb in a "plantation next to a cranberry farm." This joke is lost on modern audiences. In 1959, it was announced that cranberry crops were tainted with traces of the herbicide aminotriazole, and as a result, cranberry sales plummeted.
A young Jack Nicholson has only a small part as Farb's masochistic patient, Wilbur Force. Later, however, as the actor's career began to take off, he was prominently featured on the home-video releases to help generate interest in the film.
Charles B. Griffith stood off-screen providing the voice of Audrey Junior as a reference for the actors and actresses. The voice of the plant was supposed to be dubbed in by another actor in post-production, but Griffith's vocalization of the plant got laughs, and Producer and Director Roger Corman was notoriously cheap, so his voice remained in the final print of the film.
The shooting schedule for this film was two days and one night, because Roger Corman had made a bet that he could make a movie in two days. Charles B. Griffith took a little more than that to write it.
Charles B. Griffith put several of his relatives in the film; Myrtle Vail, "Grandmother" Myrt, for example, is actually his grandmother, and the hobo who Dr. Farb tortures in his office is Griffith's father. He also placed several of his relatives in crowd scenes. The bums in the background of the street shots on Skid Row are real transients, however, and were filmed in the actual skid row area of Los Angeles, California.
Charles B. Griffith not only wrote most of the screenplay, he also appears (uncredited) as the screaming dental patient who runs out of Dr. Farb's office, the burglar who breaks into the flower shop, and the voice of Audrey Junior.
Remade as a successful stage musical that was later adapted into the film Little Shop of Horrors (1986). The success of the musical led to the animated series Little Shop (1991), which director, Roger Corman served as a consultant on.
The manager of Producer's Studio informed Roger Corman that a large office set had been constructed for a production that was about to wrap. Corman arranged to use the standing set, redressed, as the main set of this film.
