Corrected entry: In the movie all of the guards have swords. The blades design is basically small near the hilt (the handle of the sword), and gradually gets wider and rounder near the end of it. Well, the sheath (the carrying case) of the sword is the same shape as the sword. Because of this, it would be impossible for the swords to be slid back into the sheath, the reason being that the larger end of the blade would not fit through the top of the case, for it's too small.
Corrected entry: In the scene where Jasmine is in the red and is feeding Jafar the apple she clearly has chains on her hands. When he proposes to her and she reaches for the wine she doesn't have chains on anymore.
Correction: Jafar used his sorcery to turn her chains into a crown which he offered her as he proposed.
Corrected entry: In the scene where Aladdin first wakes up the Genie, Carpet hides when Genie first comes out, but later, Genie gives Carpet a high five and makes a comment on how long its been since he'd seen him. Why would Carpet hide from an old friend?
Correction: The carpet hides as the genie first emerges because he's not sure if the time in that bottle has driven the genie insane.
Corrected entry: When Aladdin is on the princess's balcony for the first time in the middle of all the speaking a whispered voice is heard saying "take off your clothes".
Correction: The official position that Disney took was that the line is "Take off and go" and it is said by the Genie talking to Rajar the Tiger.
Corrected entry: Why did Jafar need the genie's help to make Jasmine fall in love with him? Being such a powerful sorcerer couldn't he have just done it himself?
Correction: Obviously he doesn't know that particular spell. Jafar can't be an expert on everything, and you wouldn't expect an evil sorceror to be particularly well up on love spells - it just doesn't fit with the whole 'evil sorceror' thing.
Corrected entry: Jafar's disguise changes between when he throws Abu into the cave and when he checks for the lamp.
Correction: He removed his disguise. It was a mask/wig.
Corrected entry: When Aladdin and Jasmine are singing "A Whole New World" they pass in front of a full moon on the magic carpet, and when they pass over water the reflection is of a crescent moon.
Correction: They don't pass in front of a full moon. It is a crescent moon with the rest of the moon lit by a da Vinci glow (light reflected from the Earth). Some people tried to correct this because they think the moon is in different phases depending on where in the world you are. Definitely not the case, as shown on https://sciencesy.com/pages/phases-of-the-moon. Because the moon's always facing the earth, and its phase is determined by where the sun is in relation to it, it doesn't matter where you're standing.
Corrected entry: When the apple vendor threatens to cut off Jasmine's hand, Aladdin rushes in, grabs the sword from the vendor, and hands it to Jasmine, who hides the sword behind her back. Immediately following, Aladdin takes Jasmine by the shoulders and says "I've been looking all over for you." Notice that her hands are now in front of her and the sword is nowhere to be seen.
Correction: It's called Hammerspace, which is a cartoon physic which lets them hide things in a small space and without it showing or bulging in any way. Just another example of how the cartoon world is different from ours.
Corrected entry: The rule of entering the "Cave of Wonders" spoken to Aladdin by the Cave itself is, " Touch Nothing But the Lamp". It is not until Abu snatches the ruby in the Lamp Room scene that the Cave qualifies the original edict to, " You have touched the forbidden TREASURE". Aladdin and Abu have touched the Magic Carpet plenty of times before this point.
Correction: The cave is able to determine who is "worthy" to enter through whatever mystical charms have been placed upon it. It is very likely the cave can also determine "intent", just as it has determined that Abu is Aladdins "pet" and not a second individual. Aladdin and Abu did not intend to take the carpet or other treasure they happened to inadvertently touch. It is not until Abu purposely and intentionally goes to take the ruby that the cave determines the rule has been broken.
Correction: The magic carpet was presumably an exception, as it's not really treasure but more of a guide to lead them through the cave of wonders.
Also, he did not so much "touch" with his hands as simply walk on it underfoot, couldn't entirely be helped (he comes into contact with the treasure on the floor the same way, no ill result), thereby awakening it, and further contact is initiated by Carpet himself.
Corrected entry: When Abu is on the bursting lava rocks in the Cave of Wonders, right before the last two rocks blow up you can hear him say "Holy shit", if you turn your volume up.
Correction: This is not true.
Corrected entry: In the scene where Aladdin is escaping from the cave in the magic carpet, he doesn't lose his hat in any moment, despite its being a frenetic, very fast and roller coaster-esque escape. It should have fallen off at some point.
Correction: Without knowing how tightly his hat fit you cannot call this a mistake.
Correction: The swords are not kept in scabbards at all. They are kept tucked into the belt and are drawn by simply pulling them out of their belt.
