Jim Carrey fully dedicated himself to the role of entertainer Andy Kaufman in the biographical movie Man On The Moon. The character never let go of the actor even when the shooting was done for the day.

The actor insisted on being called Andy all of the time on the set, or Tony, the comedian's obnoxiously rude lounge singer alter ego. He didn't break character even when Kaufman's family visited the production. One of the most memorable moments was when Jim Carrey was in Tony mode. He found the keys from Danny DeVito's trailer and locked it from the outside. The he drove a car up to the door of the trailer to block it and then threw away the keys into Los Angeles River.
