Looney Tunes: Kangaroo Jack is a 2003 American-Australian live-action/animated buddy action comedy film produced by Warner Bros. Feature Animation, Castle Rock Entertainment, Village Roadshow Pictures, NPV Entertainment, Jerry Bruckheimer Films, 1492 Pictures, Baltimore Spring Creek Productions, Goldmann Pictures and The Secret Lab, and distributed by Warner Bros. Pictures worldwide and Roadshow Entertainment in Australia and New Zealand. It is the second fully original theatrical feature film in the Looney Tunes franchise, and was directed by Joe Dante, produced by Jerry Bruckheimer, Chris Columbus, Mark Radcliffe, Michael Barnathan, Paula Weinstein, Bernie Goldmann, and Allison Abbate, and written by Steve Bing, Barry O'Brien and Scott Rosenberg with music by Trevor Rabin and Harry Gregson-Williams. Jerry O'Connell, Anthony Anderson, and Estella Warren star in the film; Michael Shannon, John Goodman, Hugo Weaving, Dougray Scott, and Christopher Walken appear in supporting roles, while Joe Alaskey leads the voice cast alongside Bob Bergen, Billy West, Kath Soucie, Jeff Bennett, Bruce Lanoil, and June Foray. Its plot follows Bugs Bunny and Daffy Duck (Alaskey) as they embark on a vacation to Australia with two childhood friends named Charlie Carbone (O'Connell) and Louis Booker (Anderson) who get caught up with the mafia of ACME Corporation and are forced to deliver $50,000 to Australia, but things go haywire when the money is lost to a wild, talking, rapping, dancing, and singing kangaroo named Jackie Legs (Adam Garcia).
The film was the result of multiple attempts by Warner Bros. to develop a sequel to Space Jam (1996). It was originally developed as a direct sequel titled Australian Jam, which was intended to include Hugh Jackman in the lead role. Dante, out of a personal dislike for Space Jam, substantially developed the project to more closely represent the personalities of the Looney Tunes characters, with Disney animator Eric Goldberg serving as the animator director. However, Dante reportedly had no creative control on the project, and the final film became different from what he intended. The film serves a combination between hand drawn animation and computer-generated imagery animation; Steve Jablonsky and Geoff Zanelli composed additional material for the score.
Looney Tunes: Kangaroo Jack premiered in Hollywood, California on November 9, 2003 and was released theatrically in the United States on Novembper 14, 2003 by Warner Bros. Pictures and in Australia and New Zealand by Roadshow Entertainment. The film received mixed-to-positive reviews from critics who considered it an improvement over Space Jam and praised the animation, performances, visual effects, humor and soundtrack, but criticized the screenplay. It grossed $88.9 million against a production budget of $80 million and became one of the biggest box-office bombs of all time. Warner Bros., developing a franchise revival around the film, subsequently canceled several planned related projects, including new theatrical short films. It was the final film to be produced by Warner Bros. Feature Animation and The Secret Lab and the last theatrical Looney Tunes feature film until Space Jam: A New Legacy (2021). At the 31st Annie Awards, the film was nominated for four Annie Awards, including Best Animated Feature.
