Continuity mistake: When Maurice arrives at the castle and loses his hat, the bricks the hat is over change between shots.
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. (00:53:35)
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. (00:12:35)
Continuity mistake: During the song "Gaston", Lefou throws a lot of eggs in the air, but very few come back down.
Continuity mistake: When Gaston and Lefou are talking to the man in the bar, Gaston throws the bag of gold to the lantern's right. However, when this man says, "So you want me to throw her father into the asylum?", the bag is now on the lantern's left.
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. (00:36:40)
Continuity mistake: When Gaston comes to Belle's house to propose to her, you can notice that he leaves the door open, but when he backs Belle against it, the door has magically shut. It is definitely the same door - note the items surrounding the door, and the door itself are all the same. (00:17:05 - 00:17:50)
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.
Audio problem: In the first shot of Gaston losing his balance, he cries "Woah, ah" or something, but his lips don't move.
Audio problem: Gaston throws his metal beer mug into the fire, and we hear the smash of glass.
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. (00:30:20 - 00:31:10)
Continuity mistake: After the scene where Chip bursts into the cellar, there is a wide shot of outside of the castle as the villagers get beaten up in which the windows next to the doors are gigantic. In other scenes, the windows are nowhere near that big.
