Plot hole: Scar tells the pack he didn't make it to the gorge in time to help Mufasa. However Zazu was with them at at the gorge. He could have easily told Serabi or any of the other lions on the numerous times he spoke with them, exposing Scar.
Plot hole: When the castle is about to blast off, Brad and Janet abandon Dr. Scott's wheelchair at the door of the castle and carry/drag him across the porch and down the steps. After the blast off, Brad, Janet, and Dr. Scott are on the grass and have been blown some distance apart from each other (in the UK version, there's another song where Brad and Janet crawl toward Dr. Scott so they are blown farther apart than shown in the US version). It seems extremely unlikely that the remains of Dr. Scott's wheelchair just happened to fly from the doorway to land directly under him during the blast. Brad and Janet can barely crawl so they didn't move him or it. (01:34:10)
Plot hole: Captain Smolsky only gets hit in the back with the plaster. So why, later on, is his entire body covered in hardened plaster, like a mummy?
Plot hole: When Miss Price, Professor Browne and the children return from their magical journey to the island of Naboombu and realize they no longer have the Star of Astroroth pendant, Miss Price says, "I should have known it would be quite impossible to take an object from one world into another." Yet, they had no problem taking themselves, the bed, blankets and pillows from one world into another.
Plot hole: Nogerelli says to himself that the gap past Deadman's Curve must be 100 feet wide. How on earth was Michael meant to have made a jump of 100 feet (or even a few feet less) after both being slowed down by crashing through the wooden barriers and also by not having a ramp and therefore no upwards boost? He would have plummeted to the bottom.
Plot hole: Although it is explained how the chipmunks were able to get away with the balloon race by tricking Ms. Miller, wouldn't Ms. Miller know that the chipettes were in on the balloon race? Especially considering the fact that she is their guardian? Also, why would she offer to babysit the chipmunks if she has chipettes to look after herself? Despite this, the chipettes were never brought along to Dave's house with Ms. Miller. And what is Ms. Miller still doing in Dave's house if she thinks the chipmunks are with Dave? Unless maybe she's taking care of the house...
Plot hole: The 3 minutes to destruction scene actually lasts for about 3 minutes and 30 seconds - they're lucky to be alive.
Plot hole: In the scene where the Wicked Witch is furious because Dorothy and pals have been saved from the poppy field, the Flying Monkey hands her a golden cap. She then dashes the cap across the room. The golden cap is used in the book to summon the Flying Monkeys. They shot scenes involving use of the cap, edited them out, but left this one with the cap inexplicably being tossed about. (00:57:05)
Plot hole: In the first Jungle Book movie, the role of the vultures is that they do not seem to be hesitant when helping the boy, Mowgli in need of help from Shere Khan. However, in this movie, when their obnoxious vulture friend is attacked by Shere Khan, they do absolutely nothing to help him and in fact, fly away cowardly. Did they suddenly lose all of their courage?
Plot hole: After the secret passage has collapsed, the Black Fox hires Hawkin's midget acrobat friends because the only opening left "is barely (wide) enough for a child". Yet, during the throne room brawl, Hawkins passes the swing-around rope to a guy who is much taller than the midgets.
Plot hole: When the three Marx Brothers are causing mayhem at the performance of "Il Trovatore," although we see scenes from several different acts of the opera, there seems to have been no intermission (or all the trouble would have gotten sorted out then, instead of at the end). You have to be at least a little familiar with "Il Trovatore" to notice this.
Plot hole: After Little John bores a hole in the bottom of the treasure box, several gold coins fall through the hole. The four rhinos holding the box should have noticed it becoming lighter.
Plot hole: In the scene where the Sheriff stops the cows' brawl, he gives them to the Chinese man. The Sheriff knows what Pearl's animals look like, so why didn't he recognize the cows as Pearl's?
