Continuity mistake: When the Beast discovers Belle in the West Wing, he starts yelling at her, and she backs into an old, rotting cupboard that sports many patterns and designs on it. Then when the shot changes the cupboard is suddenly new-looking and in good shape and has no patterns on it at all. (00:44:10)
Continuity mistake: After Phillipe's reins get caught in the branches, the loop of the reins becomes longer between shots.
Continuity mistake: When the Beast bursts into the West Wing after Belle refuses to go to dinner with him, he grabs the magic mirror, sees Belle, and puts it back down again. Then another petal falls from the rose, but notice that the petals on the table are in a different position than they were in the previous shot.
Continuity mistake: In the tavern, which is the setting for the 'Gaston' song, right at the end of the bar there is a thick wooden beam attached to the bar and the ceiling. You can see this beam clearly when Le Fou sings "No-one's slick as Gaston...", and he prances around and then grabs the beam. However, right at the end of the Gaston song when they sing "So his marriage we soon will be celebrating...", the camera pans backwards out to the window, but the wooden beam has vanished.
