Trivia: In this movie, Robin Williams (the voice of the Genie again) seems to spoof some of his real-life roles. I haven't seen all of them, but Mrs. Doubtfire is certainly included.
Trivia: There's an homage to Beauty and the Beast as Timon starts singing: "It is with deepest pride and greatest pleasure that we welcome you tonight. And now we invite you to relax let us pull up a chair as the dining room proudly presents your dinner!" They then show Pumba as the dinner to the hyenas. Pumba was the distraction when Simba came back to the Pridelands. (01:45:00)
Trivia: When the animators where drawing Lucifer the cat they just couldn't get it right. Then when Walt Disney saw the animator Ward Kimball's cat, a furry calico, he declared "There's your Lucifer."
Trivia: The names of three characters were switched when "Street Fighter" was released in the United States. M. Bison was originally called Vega; Vega was called Balrog; and Balrog was called M. Bison. The reason this was done because Capcom (the creator of the game) figured it may get sued by boxer Mike Tyson if there was a black boxing character named M. Bison (who already resembles Tyson enough without the name).
Trivia: In the biblical book of Jonah, there is actually no whale that swallowed Jonah. The "whale" is a mistranslation of the Hebrew word for a big fish by the translators of the King James Version. Because of the prominence, respectability, and the wide distribution (it is in the public domain in the U.S., but not in the U.K.) of the King James translation over modern translations like the New International Version, the "whale" is what most Bible readers think of the sea creature that swallowed Jonah.
Trivia: In almost every story told in the movie, there is an ashtray that is used as an ashtray, as a soap dish and as a place you can put lose change, rings etc. This is done deliberately by the director, it has become his personal trademark.
Trivia: In the beginning when Roddy is waking up, a glass Alex the Lion (from "Madagascar") cookie jar is visible on the window sill. When Roddy is looking for something to wear, one of the outfits he holds up is Wallace's sweater vest from "Wallace and Gromit: Curse of the Were-Rabbit".
Trivia: When the "Dragons" are being released around the world, you see a baby carriage nearly falling into one of the cracks that forms in the ground, only to be saved at the last minute. The baby-crying sound effects were actually provided by Selma Blair, who does the voice of Liz Sherman (and also played her in the live action film), after the makers realized she could do a perfect impression of an infant crying.
Trivia: In the Hall of Mayors, there is a picture of Dr. Seuss as JoJo's Grandfather.
Trivia: The animators created many small flaws in the film in order to emulate the looks of old comics. This includes color separation and a slight double-image effect in certain scenes to replicate imperfect comic-printing techniques. While the effect was intentional, many film-goers who saw the movie in 2D actually complained about these effects, thinking they were accidentally sold tickets to a 3D movie. (Especially due to the double-image effects).
Trivia: The two surfer dudes eating Krabby Patties after Spongebob and his friends appear, are Lloyd Ahlquist and Peter Shukoff, the creators of the internet series "Epic Rap Battles of History." They were also the writers and performers of the rap battle before the credits.
Trivia: When we see the "Walt Disney Pictures" logo at the start of the movie, the "When You Wish Upon A Star" theme is barked by the Dalmatian puppies.
Trivia: Sergei from Secret Life of Pets 2 can be seen in the bank.
