Forbidden Planet 1956

Forbidden Planet is a 1956 American science fiction film from Metro-Goldwyn-Mayer, produced by Nicholas Nayfack, and directed by Fred M. Wilcox from a script by Cyril Hume that was based on an original film story by Allen Adler and Irving Block. It stars Walter Pidgeon, Anne Francis, and Leslie Nielsen. Shot in Eastmancolor and CinemaScope, it is considered one of the great science fiction films of the 1950s,[4] a precursor of contemporary science fiction cinema. The characters and isolated setting have been compared to those in William Shakespeare's The Tempest,[5] and the plot contains certain happenings analogous to the play, leading many to consider it a loose adaptation.
In the 23rd century, after more than a year's journey, the United Planets starship C-57D arrives at the distant planet Altair IV to determine the fate of an expedition sent there 20 years before. Dr. Edward Morbius, one of the original expedition's scientists, warns the ship not to land for safety reasons, but Commander John J. Adams ignores Morbius' warning.

Adams and Lieutenants Jerry Farman and "Doc" Ostrow are met by Robby the Robot, who transports them to Morbius' residence. Morbius describes how all other members of their expedition had been killed one-by-one, by an unseen "planetary force" and how their ship was vaporized as the last survivors tried to lift off. Only Morbius, his wife (who later died of natural causes), and their daughter Altaira were somehow immune. Morbius offers to help the starship return home, but Adams says he must receive further instructions from Earth.

The next day, Adams finds Farman kissing Altaira. Furious, he dresses down Farman and criticizes Altaira for being naive and wearing revealing clothes that make her too attractive. That night, an invisible intruder sabotages equipment aboard the starship. The next morning, Adams and Ostrow go to Morbius' residence to discuss the intrusion. While waiting, Adams happens upon Altaira swimming. After she dons a new, less revealing dress, Adams apologizes for his behavior toward her, and they kiss. They are suddenly attacked by Altaira's pet tiger, and Adams is forced to disintegrate it with his blaster.

Morbius appears and tells Adams and Ostrow that he has been studying artifacts of the Krell, a highly advanced race that perished overnight 200,000 years before. One such device enhances the intellect, which Morbius had used. He barely survived, but his intellectual capacity had doubled. Another is a vast 20 miles (32 km) square underground machine, still functioning, powered by 9,200 thermonuclear reactors, operating "in tandem". Adams tells Morbius he must share these discoveries with Earth. Morbius refuses, saying "humanity is not yet ready to receive such limitless power".
