The film tells the story of two childhood friends who get caught up with the mob and are forced to deliver $50,000 to Australia, but things go haywire when the money is lost to a wild kangaroo.

It stars Jerry O'Connell, Anthony Anderson, Estella Warren, Michael Shannon, and Christopher Walken, with Adam Garcia as the uncredited voice of the titular character.

The mobster's apprentice Frankie Lombardo tries to drown Charlie, but a boy named Louis Booker saves him, and they become best friends.

Back in New York, Sal gets a call from Mr. Smith complaining that Charlie and Louis haven't arrived, then sends Frankie and some henchmen to Australia to investigate.

They spend hours wandering in the desert, during which the duo encounter a pack of dingoes and a dust storm, and Charlie hallucinates finding a jeep, and they soon meet Jessie, an American woman from the Outback Wildlife Foundation.

The police force, led by a cop working undercover as an Outback guide, arrives and arrests Frankie, Mr. Smith, and their henchmen.

One year later, Charlie and Jessie are married and have used Sal's $50,000 to start a line of new hair care products bearing a kangaroo logo, along with Louis.

Now able to speak again, Jack breaks the fourth wall, explaining why the film should end with him and closing it with his version of Porky Pig's famous catchphrase: "That's all, blokes!"

[3] The film began shooting in Australia in August 2001, lasting about six months in total, and originally included profanity, sex, and violence, intended to be released with an R-rating.

Extensive new footage that replaced the animatronic kangaroo with a new CGI one that rapped (voiced by an uncredited Adam Garcia) was shot, and the film was edited down to a PG-rated family animal comedy.

The site's critics consensus reads: "The humor is gratingly dumb, and Kangaroo Jack contains too much violence and sexual innuendo for a family movie.

[8] Joe McGovern in The Village Voice described Kangaroo Jack as "witless" and stated "The colorless script...seems to have written itself from a patchwork of Wile E. Coyote cartoons, camel farts, and every high-pitched Aussie cliché to have echoed on these shores".

"[10] Gary Slaymaker in the British newspaper The Western Mail wrote "Kangaroo Jack is the most witless, pointless, charmless drivel unleashed on an unsuspecting public".

[11] For their performances, Anthony Anderson and Christopher Walken were both nominated for Worst Supporting Actor at the 24th Golden Raspberry Awards, but they lost to Sylvester Stallone for Spy Kids 3-D: Game Over.
