Spaceballs was a spoof on Star Wars, and other space movies, but mainly Star Wars ... it was arguably Mel Brooks' last masterpiece (some people claim Robin Hood, Men in Tights was pretty good). It features Rick Moranis in the "Darth Vadar" role, and frankly, he knocks the character out of the park. John Candy plays "Barf," kind of like a friendly and funny Chewbacca.
Just a classic movie all around. They hinted to a sequel in the movie, but sadly, that never happened.
May the Schwartz be with you!
