Kangaroo Jack

Inspired by an urban legend that co-writer Steve Bing heard as a teenager, about a pair of Boston college students on break in Australia. While driving through the Outback, they accidentally hit a kangaroo with their Land Rover. Thinking they had killed it, they got out and placed the driver's Boston Red Sox jacket on the kangaroo to take a picture before moving on. However, the kangaroo was merely unconscious, and awoke in the midst of the photo-taking. It broke free and took off across the Outback, still wearing the Sox jacket...along with the keys to the Land Rover in the pocket.

Kangaroos cannot walk backwards.

During the Jerry Bruckheimer Films logo at the beginning of the movie, you can briefly see two kangaroos crossing the street.

When aired on Nickelodeon, the part where Charlie putting his hand on Jessie's breast during his mirage daze was cut out. So instead, it showed Charlie about to reach out before being hit in the head with the water canister by Jessie. Also, the part where Blue says "Never should have left the pub!" was edited out.
