Continuity mistake: When Xianniang chokes Bòˆri Khan the position of her fingers changes between shots. Note how the index finger is separated from the rest in one shot, or close to the others a shot later. (00:12:29)
Continuity mistake: When Mulan watches the flying burning catapult balls her hair is behind her shoulders. In the close-up it's over her shoulders. (01:08:51)
Continuity mistake: In the desert, when a man sees Xianniang he wipes is face with a handkerchief. The way he holds it changes between shots.
Continuity mistake: After Mulan breaks the winged sculpture she chases the chicken and runs past a couple. A mere second later Mulan is in a different place: the stuff on the wall has vanished, the ladder and, of course, the couple. There's a brief shot afterwards where you can now see the ladder but the couple is nowhere to be seen. The whole editing is a mess.
Continuity mistake: After jumping off the roof, Mulan smiles at her dad while neighbours walk away, and a strand of hair falls over her forehead. A shot later her hair is brushed. She didn't move between shots.
Continuity mistake: After slipping down the roof, Mulan smiles at her father and bends her arm. From the opposite angle the arm is lowered. (00:03:00)
Continuity mistake: After the first clash with the Witch, as the narration says Hua Jun 'dies', but Mulan lives. The close-up on the blade shows a hand gripping it a couple inches below the blade, while whenever we see her face, before and after that close-up, she is holding it with her finger alongside the guard. (01:03:45)
Continuity mistake: The commanding officer (Donnie Yen) intervenes to stop the sword-pointing nonsense with his kung-fu badassery. He easily disarms the two litigious rookies and holds both their swords, but the pose he strikes is a different one in the two shots; Mulan's family heirloom is held alternatively low and high. (00:29:55)
Continuity mistake: Once Mulan has reached the top of the mountain with her buckets, the action moves to the Rouran troops assaulting a city. Gong Li's witch is womanhandling a bunch of soldiers who try to impale her. She grabs a spear a few inches away from its feathers, but in the next shots her hand is covered by them. (00:50:50)
Continuity mistake: Mulan is having dinner with her family after her father has been drafted. During the scene depending on the camera angle her arms are folded, or her right arm is leaning against the table while she is holding chopsticks in midair. (00:20:55)
Continuity mistake: Chen Honghui extends his hand to "the little man" to help 'him' back on his feet, but Mulan pulls her sword on him. The sword strap dangles freely in the shots by the side, but it is held up in the close-ups of the blade pointed at his neck. (00:29:45)
Continuity mistake: When Mulan moves the teapot to trap the spider, the teapot is at different distance from the tablecloth depending on the camera angle. (00:17:20)
