Heavy Metal is a 1981 Canadian animated film from executive producer Leonard Mogel, who was the publisher of Heavy Metal magazine. With Ivan Reitman producing and Gerald Potterton directing, the work was expedited by having several animation houses working simultaneously on different segments, including CinéGroupe and Atkinson Film-Arts.
The film is an anthology of various science fiction and fantasy stories adapted from Heavy Metal magazine and original stories in the same spirit. Like the magazine, the film has a great deal of graphic violence, nudity, and sexuality.
A stand-alone homage titled Heavy Metal 2000 was released in 2000.
