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: When Smee gives Hook his nightcap drink, Hook takes it in his hand and holds it at the top of the goblet so that it is hidden under his hand.

Additionally, the position of the small umbrella that sits in the goblet changes a few times. (01:02:40)

Factual error: When Peevey gets stuck in the truck, Cliff fires up the rocket pack and simply pushes it clear. If the rocket pack can push out enough thrust to move a 2 1/2 ton truck, Cliff's body can't take that kind of stress. He stretches his arms out, starts pushing, and sets off the rocket, putting himself between the truck and an accelerating rocket demonstrably capable of moving it. The truck is stationary so has 2 1/2 tons of inertia. The rocket instantly accelerates it to an appreciable speed. Human arms cannot take that kind of stress. He's going to be crushed.
Continuity mistake: The king's youngest daughter climbs down a wall and drops a tightly sealed Erlenmeyer flask (invented centuries later) filled with a toxic potion.

Continuity mistake: When the Turtles first arrive on screen behind Keno, they leap over the boy to attack the thieves.

Donny and Leo switched places between shots. (00:03:35)

Factual error: In one of the train cars on the way out west, upon being asked by one of his henchman, "When are we going to eat the mice?" Cat R. Wahl replies, "Which would you rather have, the crouton or the entire Caesar salad?" Caesar salad was not invented until the 1920's and the movie takes place in the late 1800's.
Continuity mistake: Chuckie falls into the river. When Bingo rescues him, his bike is in a different place in the river.
Visible crew/equipment: Toward the end of the movie Curly Sue comes back home from the orphanage. She sees the letter from Bill and begins to walk slowly to the living room - look left to the screen and you will notice something drop from above kinda looks like something silver, maybe a boom mic.
