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)
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.
Continuity mistake: The settings and conditions of the West Wing change drastically. For instance, in the beginning, the painting is very close to the rose and there's also a red carpet underneath it, but later the painting is further from the rose and the red carpet disappears. When Belle leaves the room after the Beast releases her, there are red decorations on the floor in front of the door which were not there earlier when the Beast burst in after Belle refused to go to dinner with him. There is usually a lot of junk cluttered in the West Wing, but when the Beast takes a bath it looks much cleaner. It's an almost endless list.
Continuity mistake: When Maurice enters the castle for the first time, there are windows on either side of the front doors. These were not there when Maurice had looked up at the castle after arriving.
Continuity mistake: The length of the chip on the axe in Maurice's invention changes in the scene where he is building it, and also later when Chip is trying to get it to work.
Continuity mistake: During "Gaston", Gaston shoots his blunderbuss three times. However, four holes appear in the ale barrel.
