A spoof of the Star Wars series, with Mel Brooks playing the dastardly president of an alien race out to steal the air supply of a neighboring planet. Fearless - and clueless - space heroes Lone Starr (Pullman) and his half/man half dog sidekick Barf (Candy) wage interstellar warfare to free Princess Vespa (Zuniga) from the evil Dark Helmet (Moranis). Along the way they encounter the wise little creature Yogurt (Brooks) who teaches them the mystical power of "The Schwartz."
