This sprawling epic centers around the origins of Dark Helmet, his childhood, youth and adulthood. Young Rick Moranis builds Rosie the robot and travels to the planet of the Mogs, where we meet young Barf (played by that fat guy from Mad TV). Chris Rock plays Jahjah, a Jamaican taxi driver. Mel Brooks reprises his role as Yogurt, but now he plays a younger, more limber version of himself, fighting scores of fragile looking robots with the power of the Schwartz. As the story continues, young Rick turns to the dark side of the Schwartz and surrounds himself with Assholes. Carrie Fischer plays the princess Amigdala.
