Duel Personality is a 1966 Tom and Jerry cartoon produced and directed by Chuck Jones. It is the first Tom and Jerry cartoon released in 1966, and the first Tom & Jerry cartoon (both regarding Tom and Jerry produced by Chuck Jones, and Tom and Jerry cartoons produced altogether) with Dean Elliott as the music composer. NOTE: In the chase scene back into the mansion, Tom is seen running with 4 paws, although 2 paws normally act as hands.
