Continuity mistake: At the start, when the camera pans through the doorway of Ms. Darbus's classroom, Zeke sits on a tall stool that is about 3 feet high. Oddly enough, in the following shots, the munchkin stool he now sits on only reaches the height of about 1 foot. (Did they really think we wouldn't notice?) The wood stool also moves forward a few feet. (00:00:50)
Continuity mistake: The tiger bites the seat off the suitor's trousers, allowing the viewer to see his polka-heart boxers. When we see the tiger in the courtyard, he has a part of the same boxer shorts in his mouth. So if he bit off the seat of the trousers, shouldn't he have purple cloth in his mouth? (00:11:45)
Continuity mistake: When Sarah shouts, "Quick, this way!" and then Sir Didymus shouts, "No, not that way!" the hanging sign with the hammer hangs crookedly by only one chain. However, two shots later when Sir Didymus shouts, "You're going the wrong way!" the sign hangs properly from two chains. Then later, when the three Samurai Goblins jump in front of Sarah and the rest, the sign's chain is broken once again. (01:20:00 - 01:25:40)
Continuity mistake: The wagon, which is full of explosives, is on fire, so Mulan cuts Kahn (the horse) free with her sword and jumps onto Khan. She starts to ride away, while she holds the reins in her left hand and the sword with her right hand, up in the air. The wagon explodes and in the next shot, she still holds the reins in her left hand, though the sword, still in midair in her right hand, is now actually in its sheath, which is always attached to the left side of her belt. Some arrows are missing on the ground as well. Then her sheathed sword lands on the ground beside her. (00:53:45)
Continuity mistake: The scar on the Duke's bodyguard's face switches from one cheek to the other throughout the movie, due to flipped shots. (00:17:30)
Continuity mistake: In the scene where the crocodile attacks Hook at Skull Rock, there is a shot where the croc bites Hook's left foot and the shoe comes off, leaving Hook's left foot bare. In the shot with Hook wrapped around the croc's snout, the shoe is back on Hook's left foot and his right foot is bare.
Continuity mistake: Just before Flynn cuts off Rapunzel's hair, there is a shot from behind him and he reaches up with his right hand to push her hair behind her ear. His arm is visible up to his forearm and the shackle is nowhere in sight. However, in the next, wide shot, the shackle is suddenly up around his wrist. (01:01:20)
Continuity mistake: We see a close up of Gabriella slipping in some milk, but in the wide shots there is no milk or carton on the floor. (00:41:30)
Visible crew/equipment: In the scene during the American bandstand, at the end of the song when the teacher is dancing in front of the band members, the crews can be seen. The dressing and the hair doesn't match Grease era at all, and someone is sitting on a director's chair as well. (01:06:20)
Revealing mistake: After Sophie faints at her bachelorette party, during the next scene it cuts back and forth between shots taking place in two rooms - Donna walking into Tanya and Rosie's room, then Sophie walking into Ali and Lisa's room, and both rooms have the very same cracks and stains on the walls revealing it was filmed in the same room, but with different furniture.
Visible crew/equipment: While Barnum and Phillip sing "The Other Side" Phillip uses two stools to get up and down from the bar top. When he steps down from the bar top, in this wideshot (also the first shot of them in the pub and other shots) the two upright stools Phillip used are secured with additional support, note the floor area underneath the stools' legs have the same pattern as the rest of the floor, though we can see the outline where the pattern's lines don't match up. Additionally, we also see three actors' marks (in the shape of an "L") on the floor in front of the bar, which will be where Barnum and Phillip will stand when they agree on the ten percent. (00:36:05)
Revealing mistake: In the scene where Willy Wonka and the group of golden ticket holders enter the room with the chocolate river, Willy Wonka picks up a mushroom head with his cane. If you look closely, you can see holes under the mushroom head where he has previously done this, probably more than one take for that scene.
