Beauty and the Beast (1991)

Continuity mistake: When Gaston breaks that part of the castle off to hit Beast with it, that piece is rather short and stout (maybe 3 feet long). But a couple shots later when Beast grabs onto it, it seems to be a good 5 feet or so long and very thin.

Continuity mistake: Early in the film, Gaston throws Belle's book into the mud and she wipes it off with her white dress. However, no mud appears on her dress after she does this.

Continuity mistake: In the scene where the villagers try to take away Maurice, the position of the vines over the cellar doors changes between shots.

Continuity mistake: When the Beast and Belle are in front of the fireplace reading the book, a pot magically appears next to the coat hanger.

Continuity mistake: When Maurice first comes to the castle, there is no smoke from any of the chimneys, even though we later see that there is a fire inside.

Continuity mistake: In the opening shot of Belle's house, the gates are in the shape of Z's. Later, as she comes out of her house after Gaston has proposed saying "Me, the wife of that boorish, brainless." the gates are in the shape of X's.

Continuity mistake: When Belle approaches the door to let in Gaston, there is a plate near the door that is significantly circular. When Gaston comes in a few seconds later, the plate is more oval-shaped.

Continuity mistake: In the song "Provincial Life" Belle is sitting on the edge of the fountain reading her book. Between shots she moves further away from the fountain.

Continuity mistake: In the "Be Our Guest" song a brown dish with a spoon in it approaches Belle, but in the very next shot the spoon is gone.

Continuity mistake: When Gaston tries to kiss Belle, his hands go from being on the plank of the door, to under it, to on it again.

Continuity mistake: In the scene where Maurice is sitting next to the fireplace, there is a picture with a silver frame on one of the walls. But after the Beast has burst into the room, there is a shot of the chair Maurice is in, and the picture is now in a gold frame.

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: When Maurice comes to the fireplace the stairs are red, but when the Beast finds Maurice there and Maurice says, "I just needed a place to stay.", the stairs are now white.

Continuity mistake: Throughout the movie, the hour and minute hand that make Cogsworth's moustache keep changing sides, sometimes from one shot to the next, for example, when he makes Belle visit the castle.

Sereenie

Continuity mistake: When the Beast brings Belle into the library, there is a huge globe on the ground, but in the next shot, as Belle passes over it, the globe is much smaller and is now on the table.

Continuity mistake: In an overhead shot as the villagers enter the castle, there is a blond man in a brown coat carrying a torch. A second later, as the brawl begins, this man's torch has been replaced by an axe.

Continuity mistake: In the very short scene where the Beast throws Maurice into the machine and it carries him away, the front entrance of the castle is utterly different from normal. For instance, normally there are no stairs leading up to the castle, the statues on either sides of the doors are different, the walls next to the entrance are shaped differently, and so on.

Continuity mistake: In the scene where Lumiere and Cogsworth are persuading Belle not to go to the West Wing, the width of the red carpet on the stairs changes, it becomes much wider between shots.

Continuity mistake: When the Beast brings Belle into the library the books on the table change between shots.
