Outkast star BIG BOI is heading back to the big screen as the star of a new golfing comedy. The hip-hop star, who made his big screen debut in ATL and Idlewild this year (06), is shooting WHO'S YOUR CADDY? in which he'll play a character loosely based on Rodney Dangerfield's bigwig character in Caddyshack. Big Boi - real name ANTWAN PATTON - will play a rap music mogul who joins an all-white country club.
