Next month, American Masters presents a biography of Mel Brooks, and one of the surprises tucked inside that program is Brooks’ assertion that, despite its poor critical reception at the time of release, his 1987 Star Wars parody, Spaceballs, has now sold more copies on DVD than any other Brooks film. See it for yourself, and decide whether the satire, starring John Candy, Bill Pullman, Daphne Zuniga, Rick Moranis and Brooks himself, deserves a higher grade.
