Spaceballs is a 1987 American science fiction parody film co-written, directed by, and starring Mel Brooks. It was released by Metro-Goldwyn-Mayer on June 24, 1987, and earned only modest returns, but has gone on to become a seminal cult classic on video and probably Mel Brooks' most popular film. Its plot and characters contain numerous parodies of elements primarily from the original Star Wars trilogy, as well as Star Trek and other popular science fiction films, like Alien.
Planet Spaceball, led by President Skroob (Mel Brooks), has wasted all of its air, leaving the inhabitants to survive off canned oxygen called Perri-air. Desperate to find more, plans for the extraction of all the air from planet Druidia are made. They plan to kidnap the Druish Princess Vespa (Daphne Zuniga), who is about to marry the narcoleptic Prince Valium (Jim J. Bullock). Resenting this marriage, Vespa runs off from the altar with her Droid of Honor, Dot Matrix (Joan Rivers' voice and Lorene Yarnell's body), and escapes into space, where she is attacked by the Spaceballs under the command of Dark Helmet (Rick Moranis).
