Trivia: A little nod to another Blue Sky Studios Production, "Ice Age". When Rodney is looking around Robot city, he comes across a red robot that plays hip-hop. As Rodney walks away nervously ("Uh, n-n-never mind"), pause the frame just before the shot changes and you'll see (on the left) a yellow, mechanical Sid. Sid is the sloth (and the main character) from "Ice Age". (00:15:25)
Trivia: As already noted, Hercules wears a lionskin which is made out of Scar. In the myths of Hercules one of his great tasks was to kill a vicious lions and he kept the skin ever since. But it's more than just a joke or a cameo that he wears Scar, for both Scar and Hercules were animated by the same man (Andreas Deja).
Trivia: The movie contains a spoof of Saving Private Ryan, where Manny is hit by a geyser and temporarily loses his hearing. Incidentally, the German voice for Manny, Arne Elsholtz, also synchronizes Tom Hanks, who also stars in that movie, which creates an inside joke by happenstance in the German version.
Trivia: Back when the movie was in the pre-planning stages, the story was supposedly going to revolve around the GS Ball, which Ash and company carried all throughout the Orange Islands and 1/3 of the way through Johto. Evidentally, the GS Ball was going to be finally opened to reveal that Celebi was hidden inside. This may have been the movie's plot had Pokémon Crystal not come out for the GameBoy Color.
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: The ancient legend in the tablet is very different in both versions. In the English version, it says that the Titans of Ice, Lightning, and Fire must be stopped by collecting the three treasures and awakening the beast of the sea, and the world will turn to Ash. In the Japanese version, it says that the God of the Sea will battle the Gods of Fire, Ice, and Lightning, and will fail, thus a superior master will rise up and save the world. The last line "and the world will turn to Ash." is not in the Japanese version, as Ash's Japanese name is Satoshi, named after the creator of Pokémon, Satoshi Tajiri.
Trivia: The "fighting is wrong" moral ending exists only in the American version. In the original Japanese, the ending was that Mewtwo accepted it could be a proper Pokemen in spite of having been brought to life by humans, because Ash (Satoshi in the original Japanese) is still a proper human in spite of just having been brought (back) to life by the other pokemon.
Trivia: During the sequence with the explorers' huge submarine submerging, one of the computerized "extras" can be seen waving at the camera. (He is seen through the lower window for only a second or two; use frame advance to view it or listen to the Visual Commentary on the DVD for specifics). (00:16:39)
Trivia: The date for the newspaper Professor Utonium and Hobo Jojo read is Wednesday, July 3, 2002. That's the day the movie was released into theaters.
Trivia: This film has more songs and speaking characters than any other Disney film.
Trivia: Basil of Baker Street is named after Basil Rathbone, the actor who played Sherlock Holmes in several films.
Trivia: In every Final Fantasy video game, and the movie, there is a person named Sid (even though sometimes it's spelled with a 'c').
Trivia: While Centipede is on the skeleton ship, he enters into a room where the Skeleton Captain is laying on a compass, and Centipede murmurs, "A Skelington?" This was probably a reference to a previous Tim Burton character, Jack Skelington in "The Nightmare Before Christmas". The fact that the Captain greatly resembles Jack supports this theory.
Trivia: Walt Disney's Fantasia was the first film in history to use stereophonic sound.
