Forbidden Planet (1956)

One of those most rare of Hollywood blockbusters whose plot turns on a psychoanalytic concept—namely, the id, in its primitive aspect. Leslie Neilsen (yes, that Leslie Neilsen) leads a landing party of horny astronauts in an exploratory mission of an alien planet. A father and daughter are found there, the lone survivors of a colonization attempt, living now in what appears to be the malignant paradise of an all-inclusive Cancun resort, complete with robot man-servant. They have been living in bliss and harmony, since years before a mysterious entity had murdered the rest of the settlers; the father warns that the entity may attack again. Soon the crewmembers of the landing party begin to die. It is revealed that the long-extinct previous inhabitants had created a vast machine buried in the depths of the planet that can manifest the unconscious urges of its user; the id, as the philosopher would say, is given extension. The debonair father, goateed gentleman scientist, and master of ceremonies, his family idyll threatened from without, has no choice but to release his unconscious and murderous rage: he must protect his forbidden desire by whatever means.
