Inspired by the fantastic stories and the exceptional graphic qualities of the comic book artists of comic magazine Métal Hurlant, Heavy Metal is the first cinematographic experiment where film, music and animation are combined. The film takes us on a journey to a universe where even sci-fi fails short. A universe of black magic, mysteries and fantasies. A world of dreams and nightmares. The story is about a world dominated by the Loch-Nar, the ultimate symbol of evil, which manifests itself in the shape of a green sphere. The power of the sphere corrupts everything: galaxies and time dimensions. This smorgasbord is served with a lot of rock music and humor.
