Trivia: When the tiger kitten transforms, if you watch it frame by frame its head bears a striking resemblance to Mickey's head. There is a long standing tradition for Disney to put 'hidden Mickeys' in their movies.
Trivia: The director allowed Robin Williams to ad lib through most of his voice recordings, as long as he stuck to the script where it was necessary. He was free to make his own jokes - the art crew then animated the Genie based on the best cuts of Williams' recordings.
Trivia: Sultan is zooming around the throne room on the Magic Carpet. Sultan swoops down, barely hitting Aladdin and Jafar, but does hit Iago. Step frame by frame throughout the scene and as Sultan enters the shot on the left, Aladdin's face "Morphs" dramatically for two frames into a gigantic, Mickey Mouse-like head, three times normal size. This was an inside animation joke, only noticed at frame by frame speed.
Trivia: In the original theatrical release of Aladdin, the opening song, "Arabian Nights" was different. American citizens of Middle Eastern descent took offense at the line referring to the Middle East as a place where, " They cut off your ear if they don't like your face, It's barbaric, but hey, It's home". This version still survives on the original music cassette release of the Disney Music, "Songs from Aladdin" tape, as well as on the movie soundtrack. The cassette was released the week of the movie in retail stores. The written lyrics are also in the various original Disney Music Publishing "Score from the Movie Aladdin", sheet music books. In the video release, the song was looped in with new lines" Where it's hot and immense and the heat is intense, It's barbaric, but hey, It's home".
Trivia: When the Genie (under Jafar's control) lifts the palace into the air, a member of the crowd yells a Wilhelm Scream.
Trivia: When Aladdin initially meets Princess Jasmine in the marketplace, a bushel of apples make up a "Hidden Mickey" at one of the vendor's fruit stands.
Trivia: The first part of the theme of 'Prince Ali', the parade song, is (unintentionally, I'm sure) almost chord for chord and note for note the same as 'To Life' from "Fiddler on the Roof." Duplicated chord structures are extremely common, and similar themes certainly aren't rare, but this is an unusually blatant example.
Trivia: Disney created the fictitious Agrabah for the film because the story is traditionally set in Baghdad. This was done because of the notoriety of Iraq (whose capital is Baghdad) in the Persian Gulf War a year before the film's release.
