When Forbidden Planet arrived in cinemas in 1956, it was a daring investment in a small genre. At a time when science fiction meant low-budget monster movies and tales of alien invasion, MGM spent big on something far more ambitious: a movie that imagined a world of interplanetary travel, robotics and alien civilisations with real seriousness and scale.
The premise is a familiar sci-fi trope now, but wasn’t then. United Planet Cruiser C-57D crosses the stars using a faster-than-light “hyperdrive” and lands on distant Altair-4. Its mission: find out what happened to the colony there.
