Looney Tunes Presents: Back in Action is a 2003 American live-action/animated fantasy spy comedy film directed by Joe Dante. It is the third feature-length live-action/animation hybrid film to feature Looney Tunes characters, after Who Framed Roger Rabbit (1988) and Space Jam (1996). The plot follows the Looney Tunes gang as they help aspiring daredevil Damian "D.J." Drake, Jr. (Brendan Fraser) and Warner Bros. executive Kate Houghton (Jenna Elfman) find the "blue monkey" diamond in order to prevent the evil Mr. Chairman (Steve Martin) of the ACME Corporation from using it to turn mankind into monkeys that will manufacture his products; the group also attempts to rescue D.J.'s father (Timothy Dalton), an actor and spy who has been captured by Mr. Chairman.
