Spaceballs (MGM 1987 – 97 minutes) An American space opera parody film co-written, produced and directed by Mel Brooks. It is primarily a parody of the original Star Wars trilogy, but also parodies other sci-fi films and popular franchises including Star Trek, Alien, The Wizard of Oz, 2001, Planet of the Apes, and Transformers. The film stars Bill Pullman, John Candy and Rick Moranis. In addition Mel Brooks plays a dual role.  Dom DeLuise and Rudy De Luca make  cameo appearances. In Spaceballs, heroic mercenary Lone Starr (Pullman) and his alien sidekick Barf (Candy) rescue Princess Vespa (Zuniga) of Druidia and her droid, Dot Matrix (Yarnell, voiced by Rivers), from being captured by the Spaceballs, led by President Skroob (Brooks), who want to use Vespa as ransom to obtain Druidia's air for their own planet. However, the heroes get stranded on a desert moon, where they encounter the wise Yogurt (also Brooks), who teaches Starr about the metaphysical power known as "the Schwartz". Meanwhile, Spaceball commanders Dark Helmet (Moranis) and Colonel Sandurz (Wyner) lead the search for them, but are hindered by their own incompetence.
