Trivia: When the film was released during the war with Iraq, the poster of the film was edited by airbrushing the peace sign that Amanda Bynes made. This was done by Warner Bros. so no one will think that the poster is a war protest, or make it seem that the studio is against the war.
Trivia: In the casino, while D.J. is fighting with Yosemite Sam's goons, Daffy tells him to "bite his ear." This is a reference to boxer Mike Tyson, who bit off a portion of Evander Holyfield's ear during a match.
Trivia: When Roy is talking about his ideal life with Lynn, he mentions his three children, "Vera, Chuck and Dave," a very slick reference to the Beatles song "When I'm 64."
Trivia: During the film's opening number, pay attention to the shot when Kenai is riding the back of the mammoth, busting through the fishing net that his brothers are holding. If you look very closely, you'll see Nemo, from Finding Nemo, right there along the flying salmon. He's only in three short frames, so it helps if you pause the DVD and go frame by frame. (00:04:45)
Trivia: Lara tells Terry that she will take "four minutes" with Chen Lo. The fight sequence between her and Chen Lo ends almost exactly four minutes later.
Trivia: Originally, the story was very different. The kangaroo appeared only in one scene, but the crew liked it so much, they changed the whole movie.
Trivia: When Captain Aubrey makes the toast 'To wives and sweethearts - may they never meet' he is following a custom in the Royal Navy called the toast of the day. There was a special toast for every day of the week. This one in particular was usually for Saturdays. There is a minor mistake, however: tradition dictated that the proposer (in this case, the captain) would say the first part 'to wives and sweethearts', to which the most junior officer present would reply 'may they never meet'. Here is the list that seems to be most commonly followed dates from before Trafalgar, courtesy of the Canadian Navy website: Monday - our ships at sea, Tuesday - our men, Wednesday - ourselves, because no one else is likely to both, Thursday - a bloody war or a sickly season (to ensure quicker promotion), Friday - a willing foe and sea room (The two preceding seem to be of historical interest only), Saturday - wives and sweethearts - may they never meet (reply is made by the youngest officer present) Sunday - absent friends.
Trivia: At the start of the movie, when Juni says, "To finding lost toys", he finds a toy that bears a resemblance to Grandpa in the red armor in the game when he finds "Megalegs".
Trivia: Although the movie was almost a completely different story than the book, they did make reference to a scene in the book: when you see the guy in the beginning in the hospital, he has blood all over his face. The reason is because right before then he was talking about Quantum Foam and then went into convulsions, then started spewing up blood...gory, but a nice add in to let us know that the writers actually read the book.
Trivia: Chapter 17: At home with the Triplets. After entering the apartment building, the Triplets, Madame Souza, and Bruno climb multiple flights of stairs. On their right, they pass a bathroom with an open door with flies swarming about, taking off then landing again on the contents of an unflushed toilet. If you glance at the turd in the bowl, you will see that it is in the shape of a most famous mouse. (00:41:15)
