In the 1956 film Forbidden Planet, Shakespeare’s The Tempest provides the story’s loose inspiration.
The film transfers several ideas from Shakespeare’s play to a science-fiction setting on the planet Altair IV. Dr. Morbius resembles Prospero as a learned figure living in isolation with extraordinary control over his surroundings. His daughter Altaira echoes Miranda, while the robot Robby has often been compared with Ariel. The film’s mysterious invisible force also serves as a science-fiction transformation of the destructive powers associated with Prospero’s magic.
Forbidden Planet is not a screen adaptation of Pandora’s box, but it belongs to the same family of cautionary stories about knowledge, power, and consequences. Its central danger comes from the Krell’s advanced technology and Morbius’s unconscious mind rather than from a mythic jar.
The film was directed by Fred M. Wilcox and released by Metro-Goldwyn-Mayer. Its electronic score and visual effects helped make it a landmark of 1950s science fiction.
