"Ghostbusters," Groundhog Day," "National Lampoon's Animal House" and "Caddyshack." He also wrote "Meatballs," "Stripes," and "Back to School." His more recent films included Robert De Niro's "Analyze This" and its sequel "Analyze That," "The Ice Harvest," and the 2009 biblical comedy "Year One."
He joined Chicago's famed Second City improv comedy troupe in 1969 while working a day job as jokes editor at Playboy magazine. His first Hollywood hit was the 1978 blockbuster hit "National Lampoon's Animal House."
