Galaxy of Terror is a 1981 American science fiction horror film produced by Roger Corman through New World Pictures and directed by Bruce D. Clark. It stars Edward Albert, Erin Moran, Ray Walston and Taaffe O'Connell. Set in a dystopian future where humanity is a spacefaring race ruled by a sole person called "The Master," the film features a space crew confronting primal fears after they are marooned on a distant planet.

The film has many of the hallmarks associated with the "B-movie" style Roger Corman became known for - low budget, clever set designs, talented, up-and-coming production personnel, and lots of exploitive material, including one of the most notorious scenes in cinema history.
