Meet Dave (2008)

Talk about a small part: Eddie Murphy plays a one-and-a-half-inch-tall creature from planet Nill who comes to Earth disguised in a computerized, human-size self. Much of the action takes place within the ''Dave'' machine. ''You are inside the inner workings of a robot,'' says Brian Robbins, who also directed Norbit. ''There's different chambers and a whole crew that runs this thing.'' Gabrielle Union plays mini-Dave's second in command and love interest, but we're really excited to find out who tackles the part of Lieutenant Buttock, the officer in charge of — you guessed it — the badonkadonk.
