Continuity mistake: In the 'Gaston' song sequence, near the end, Gaston is sitting in his huge antler chair with Lefou. In the wide shot, there is a bear rug behind the chair. The camera does a close up of Gaston, then in the next wide shot, the chair is on top of the bear rug. Also, after this, Gaston gets up off of the chair and in the next shot, both the chair and the rug disappear completely. (00:29:20)
Continuity mistake: During the jail breakout, when Jake tries to open the ORV's door, in the shot facing Francis he is holding the gun in his left hand as he tries to open the door for his brother with his right hand. In the next shot facing Jake just before shouts, "I don't have the handle, open the lock!" Francis's gloved left hand is empty, and next shot, the gun can be seen in his right hand. (00:01:45)
Continuity mistake: Straight after the second task Hermione wraps her own white towel round Harry, but between shots it jumps back to her shoulders, then back to Harry's several times. (01:35:05)
Continuity mistake: When Adam Banks is playing in one of the games, he scores a goal and his teammates on the bench stand up and cheer when he scores. Problem is, Adam Banks is on the bench too.
Other mistake: In the beginning of the movie, when you first see Mary-Kate (aka Mel) and Ashley (aka Ally), Mary-Kate walks off without ever closing her locker.
Continuity mistake: At Skull Rock, after the crocodile has nipped off a good bit of Hook's clothing, sock and shoe, when Hook rushes toward Smee in the boat the crocodile opens his mouth, and just as he swallows Hook he's nearly fully clothed and wearing both socks and both shoes.
Continuity mistake: The buttons on Amos Slade's shirt repeatedly change sides between shots throughout the movie. One example is while Copper and Tod are swimming, when Amos tells Chief that Copper has strayed off again, the buttons on Slade's shirt go from being on the left to being on the right, then back to the left again. (00:21:50)
Continuity mistake: Towards the end while Maleficent becomes the phoenix, the two soldiers over there leave the tower twice.
Other mistake: When Jack first arrives in Christmas Land he doesn't know what is falling from the sky (snow) but he somehow knows that the children are throwing snowballs.
Continuity mistake: When Marty chases after Biff on the borrowed 'skateboard', Marty is wearing a dark grey belt and a red/blue print shirt under his red/beige jacket. However, when Marty is hanging on to the front of Biff's car as they turn a corner (and in another shot), Marty (stunt double) is wearing a light brown belt and solid tan shirt. (01:07:00)
Continuity mistake: When Alice leaves to think over Hamish's proposal and chases after the White Rabbit, the heels on her shoes change, but when she falls into the hole the heels are back once again.
Continuity mistake: When Dr. Dolittle is giving CPR to the bear, the bear is completely dry. If you just rescued something from the water, it should be wet. (00:35:30)
Continuity mistake: After receiving the phone call from Nancy, when Robert and Morgan are talking in the taxi, his seatbelt repeatedly changes from over to under his trench coat collar. (00:16:45)
Visible crew/equipment: During the Quidditch match Harry's broomstick tries to shake him off, due to the spell. After Hermione tells Ron, "Leave it to me," in Harry's last close-up before he flips over, the seat that is attached to the broomstick, to make it more comfortable for Dan Radcliffe to sit on, is entirely visible. Glimpses of other seats can be had during the match as well. (01:20:50)
Continuity mistake: When Tom the Minion dressed as a maid is hoovering, he answers the front door by opening it towards him as does the minion who looks out of the door after Tom has been taken. In the scene with Gru sat on the steps in the rain, sad that Lucy is off to Australia, Agnes comes out with an umbrella, but now the door opens outwards.
Continuity mistake: After Belle says good morning to Jean Potts, when she feeds the apple to the donkey note the rope (crosstie) is tied off at the donkey's throat, but in the next closeup the rope is tied off directly to the halter knot at its cheek.
Continuity mistake: The chutes that Wednesday and Pugsley use changes positions when Fester chases Wednesday.
Other mistake: Even though it is snowing throughout much of the movie, none of the snow seems to stick to any of the characters' fur. Even during the fight scene when they are rolling around in it, they are never covered with white.
Continuity mistake: In the beginning scenes, where Milo Thatch is practising his proposal, he slides over (face forward, chest against the board) a chalk drawing of a map detailing the location of Atlantis. When he realises he wiped off the drawing, and sees it on his clothes, he stands in front of the blank part of the chalkboard, "filling in" the space with the map that rubbed off on his shirt - the only problem is, that the image should have rubbed off backwards as he was facing the board when it transferred to his clothes. He could not simply stand in the place of the missing map face forward and have it read properly.
Character mistake: When Stuart calls home from the pay phone he's talking into the wrong end of the phone.
