Lampooning everything from Star Wars to Star Trek, this outrageous send-up of epic sci-fi movies is full of cosmic crazies. Fearless--and clueless--space heroes Lone Starr (Bill Pullman) and his half man/half dog sidekick Barf (John Candy) wage interstellar warfare to free Princess Vespa (Daphne Zuniga) from the evil clutches of Dark Helmet (Rick Moranis). On the way to the rescue--in their Winnebago--they confront the huge, gooey Pizza the Hutt (voice of Dom DeLuise), sassy robot Dot Matrix (voice of Joan Rivers) and a wise little creature named Yogurt (Mel Brooks), who teaches them the mystical power of "The Schwartz" in order to bring peace--and merchandising rights--to the entire galaxy.
