Deliberate mistake: At the end of the film, Gaston shoots the Beast with an arrow and pushes the Beast out the window. When the Beast lands on the edge of the castle rooftop, the arrow has disappeared. Even if part of the arrow has broken off, a piece of it would still be in his back. [This, like many other incidents in the film, is a longtime Disney animated tradition. The company seems to believe that violence is less unpleasant if all evidence of it disappears quickly. This is why so many cuts seem to disappear or become less serious. The arrow vanishing is just another example.] (01:16:55)
Continuity mistake: In the scene where the Beast gives Belle the library, the Beast is wearing a white long-sleeved shirt. When the shot changes to wider view of the Beast and Belle with Lumiere, Cogsworth, Mrs. Potts, and Chip in the foreground, look carefully at the Beast. As he holds hands outwards with Belle, the white sleeves are gone. (00:50:50)
Continuity mistake: When Belle jumps off the horse-drawn carriage and goes into the bookshop, the bookshop window consists of four glass panels alligned in vertical columns. However when Belle leaves the bookshop, the window has suddenly changed to consisting of three glass panels alligned in vertical columns. (00:04:25)
Continuity mistake: When Belle lets Mrs. Potts in, she then walks backwards into the wardrobe, and you can clearly see the wall from the bed to the corner is made up of three large purple wall panels. However in a later shot, when the wardrobe opens her doors and the moths flutter out, the wall is now made up of four purple panels. The design on the panels differs too. (00:30:20 - 00:31:10)
Continuity mistake: The eagle in the bar constantly changes size throughout the "Gaston" song.
Audio problem: During the fight scene at the end, Gaston says, "It's over, Beast. Belle is mine." But, originally, Gaston said "time to die" instead of "Belle is mine." (They wanted to involve Belle more in this scene, and decided to simply overdub the line). Unfortunately, you can tell what's been done, for Gaston's lips still say "time to die."
Continuity mistake: When Lumiere and Cogsworth are trying to persuade Belle not to go up the stairs to the West Wing, they start suggesting other places to go. When Lumiere says "..the gardens, or the library.." you can see that Cogsworth, Lumiere and Belle are all standing on the same step. Then when it cuts, Belle is standing on the step below Lumiere and Cogsworth. (00:42:05)
Continuity mistake: Gaston wears a quiver in the scenes where he is after the Beast, and the brown quiver strap runs across his body over his red shirt. After Gaston stabs the Beast with his knife, the brown strap and quiver is still on. However it then cuts, and as he starts to fall, the brown strap of the quiver has gone. Then in the next shot the strap is back on, over his red shirt. (01:16:15)
Continuity mistake: During 'Belle', we see Belle sit beside the fountain in an overhead shot, and there is a woman washing a white sheet in the water, with nothing beside her. Then it cuts to a closer view of Belle and you can now see a blue basket of white sheets on the floor beside the washing woman. (00:05:00)
