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.
Because Robin Williams ad-libbed or improvised so many of his lines, the film was ruled ineligible for the Adapted Screenplay category at the Academy Awards.
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".
If you look closely, the motif design on the Carpet is the Cave of Wonders! Fire in the back, the tiger head in the corners, and Genie's smokey body matter in the center.
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.
In the original screenplay, Iago was the calm and collected character, while Jafar was the sarcastic one. During production, it was decided Jafar's sarcasm didn't fit his role as the villain, so the two personalities were switched.
