Continuity mistake: During the "One Jump" song Aladdin sings "You're my only friend Abu", and the both swing into the harem. From the outside the window is so small Aladdin just makes it through feet first. However once inside the window is very large. A harem girl wraps a scarf around Aladdin and spins him into the matron. She chases him back to the same exact spot where the window was, and now it is a large balcony that the girl pushes him off.
Continuity mistake: Thoughout the scene involving the Apple Vendor, the support on the left side of his canopy is a large and obviously forked tree branch. Then, at the end, after Abu takes a bow and spills all of his stolen goodies from his vest, the Apple Vendor hollers out," Stop, you little thieves". The support on the left side of his stand is very shown next to him, is an single, straight and unforked branch.
Continuity mistake: While Aladdin is in the stranded in the frozen wasteland, the scene cuts back to the newly evil Palace now sitting on the hilltop. You can see stairs leading up to the throne room doors. When Aladdin returns and flies by this same spot, the stairs are gone. An interesting note here is that both of the mentioned views only show the Palace itself on the mountain top, without the surrounding walls and gardens. When Jafar has become a Genie and is being sucked down back into the palace, (on the mountain top), the shot looking down at the palace shows it to have it's walls and gardens still attached. (01:12:05 - 01:13:00)
Continuity mistake: The Prince Ali parade climbs the staircase to the throne room. Watch this scene in slow motion, or frame-by-frame and you will see that Jafar disappears as the Sultan opens the door. There is no obstacle in front of the door where Jafar is supposedly slammed into the wall, and the doors swing open through the Sultan. Also, Iago suddenly appears crushed on Jafar's shoulder.
Continuity mistake: In the Prince Ali parade, the monkeys are on top of wooden poles, with wooden cross member arms, with bells hanging from them. When Jafar is pushing the participants out of the Throne room doors, we see one of the monkeys and the bells are missing from the pole he is sitting on. (00:48:10 - 00:49:00)
Continuity mistake: When Aladdin rescues the beggar boy and girl from the wrath of the suitor prince with the whip, the width of the street directly in front of the wooden palace gates can be seen. Later when Jasmine and Aladdin go to the reception stand at the top of that very gate to announce their engagement, the street is now 10 times wider when you look at the crowd. Did they level several blocks of homes for the occasion?
Continuity mistake: When Aladdin is in the "One Jump" Song sequence, he sings "You're my only friend, Abu" and they swing into a Harem type room. The wall is covered with a giant rug weaving loom. It is in every shot. Then the matronly woman says "I'd blame parents except he hasn't got 'em". She chases him out of the window, The gigantic rug loom that once commanded the entire wall space behind the entire scene has disappeared.
Continuity mistake: When Aladdin first notices Jasmine enter the marketplace, a side street or wide alley way separates the apple vendor's stand and the melon vendor's stand where Aladdin was sitting on the canopy, (easily seen in the opening long shots). Just after Jasmine is accused of stealing, the two stands are directly next to each other, against the same building, very evident when Aladdin first tries to turn Jasmine around to walk off. Then after Aladdin finally has convinced the apple vendor that Jasmine is crazy, Aladdin says "Come along sis. time to see the doctor", the side street between the two stands has reappeared, and the stands are at least several feet apart.
Continuity mistake: Aladdin, Magic Carpet and Abu have returned to the evil throne room. Aladdin tries to grab the lamp, but is unsuccessful. Abu runs for it and is turned into a toy cymbal clanging monkey. Magic Carpet swoops down to grab the lamp a split second after Abu is transformed, yet Abu is nowhere in sight on the floor even though he was directly next to the lamp clanging his cymbals. (01:15:00)
Continuity mistake: Near the end of the "Street Rat" song, Aladdin tucks Abu into bed on a little pillow by the window. The next shot from outside, shows Aladdin opening the curtain. Then you next see a shot looking out the window from the room, looking towards the palace. Abu and his little pillow are obviously missing from view. If they show up on the DVD version being released this fall, in a wide screen format view, they still are in the incorrect position. They should be in front of the red pillow.
