Spaceballs is a science fiction spoof film written by, directed by, and starring Mel Brooks. Opening on June 24, 1987, it earned only modest returns, although it has gone on to become a cult classic on video. Its plot and characters contain numerous parodies of elements from Star Wars and other popular films. The script was written by Mel Brooks in only six months, and was approved by George Lucas, as he was a big fan of Brooks' previous films.[1] Lucas's Industrial Light & Magic was also involved in the special visual effects for the film. Despite the PG rating, there are uses of strong profanity.
