Little Shop of Horrors (1986)
Little Shop of Horrors is a 1986 American musical comedy film directed by Frank Oz. It is a film adaptation of the off-Broadway musical comedy of the same name by composer Alan Menken and writer Howard Ashman about a nerdy florist shop worker who raises a vicious, raunchy plant that feeds on human blood. Menken and Ashman's Off-Broadway musical was based on the low-budget 1960 film The Little Shop of Horrors, directed by Roger Corman. The film stars Rick Moranis, Ellen Greene, Vincent Gardenia, Steve Martin, and Levi Stubbs as the voice of Audrey II.
