Forbidden Planet is a 1956 American science fiction film. Produced by MGM, it was directed by Fred M. Wilcox and stars Walter Pidgeon, Anne Francis, and Leslie Nielsen. Forbidden Planet is the first science fiction film in which humans are depicted traveling in a starship of their own creation and was also the very first science fiction film set entirely on another world in interstellar space, far away from the planet Earth. Forbidden Planet is considered one of the great science fiction films of the 1950s, a precursor of what was to come for the science fiction film genre in the decades that followed. The characters and isolated setting have been compared to those in William Shakespeare's The Tempest, and its plot does contain certain story analogues and a reference to one section of Jung's theory on the collective unconscious.
