Continuity mistake: When the Beast claws the painting of himself in human form, he tears his right eye. When Belle comes into the West Wing later, neither of his eyes are torn.
Audio problem: In the first shot of Gaston losing his balance, he cries "Woah, ah" or something, but his lips don't move.
Continuity mistake: After the brawl between the villagers and the objects, a lot of mess is on the floor. Then when the objects jump for joy, the mess is gone.
Continuity mistake: Just before the new "Human Again" song, Cogsworth is telling the other servants what to do. He is standing on the dog/footstool and tells everyone to clean up the castle. All the servants run off including the dog/footstool and Cogsworth falls down the stairs. A load of cogs fall out of him and Lumiere picks one up. It is quite small but as he dusts it off it grows and when he hands it to Cogsworth and it has grown in size again to over double the size it was when it first fell out of him.
Continuity mistake: When Gaston is singing "Kill the Beast", he is scaring Lefou. Lefou has a bit of his white shirt visible underneath his coat. When he is climbing backwards up the stairs, this spot has changed to green. When he marches away, the spot is white again.
Continuity mistake: When Lumiere and Belle go into the dining room before the 'Be our Guest' song, in a wide shot when Lumiere says "Ma chere mademoiselle," you can see by the left wall there is a stone statue of a bird. However when it cuts to the following closeup of him, the statue has gone.
Continuity mistake: After Belle lets Mrs. Potts in and walks backwards into the wardrobe, the panelled wall is bare. Then in a later wide shot when the wardrobe says "We all think so." there is a wall candelabra in between two panels which then disappears again later, when the wardrobe opens her doors and the moths flutter out.
Continuity mistake: When Maurice is getting ready to go back to find Belle, and is pocketing compasses and rolls of paper, he takes a scarf from a drawer, leaving the drawer pulled open, with a red scarf hanging out of it. Then when Gaston and Le Fou enter the house, the drawer is pushed shut with no red scarf hanging out.
Continuity mistake: In the slightly changed version with the song 'Human Again' added, when Cogworth, Mrs. Potts, Chip etc. are talking about there being "Something there that wasn't there before...", just after the "Something There" song, In this scene Chip's chip is in the left side of his cup. It is meant to be in the right.
Continuity mistake: When Maurice is being chased by the wolves, he runs up to the gates of the Beast's castle and grabs the bars. You can see in a wideshot that he is holding the bars around the area of the patterned strip of the gate. However when it cuts to a closer view, and he pushes the gates open, he isn't holding the patterned strip of the gate, but just the normal bars.
Continuity mistake: At the end of the 'Something There' song, Belle is sitting at the fireplace and Beast hangs her coat up on a stand. Next to the coatstand you can see a bookcase with a statue on top of it. However when it suddenly cuts to Cogworth and Mrs. Potts, who are watching them from the doorway, still singing, the coatstand, bookcase and statue have all vanished.
Other mistake: At no point in this movie is the background of a room ever reflected in a mirror - even if the characters themselves are reflected in it.
