Continuity mistake: When Mulan is in with the matchmaker, she starts to pour the tea and spills a bunch of it on the table. A few seconds later she climbs on top of the table to take the tea with the cricket away from the matchmaker. She crawls right onto the tea on the table but has no wet marks or anything on her and the tea is no longer there.
Continuity mistake: In the scene where Mulan throws the tea onto the matchmaker, the matchmaker only has a little bit of blush on that is really light, but then when she has a close up to her face, there is a lot of blush on her cheeks and it is a much brighter pink. This has nothing to do with her being mad because only the blush changes not her whole face color.
Continuity mistake: During the final battle scene, Mulan is seen on the roof of the palace, lining up a shot with the rocket. She backs up, and Shan Yu bursts through the roof, leaving a large hole. As Mulan and Shan Yu fight, the hole disappears for a few shots. But later, after Mushu fires the rocket into Shan Yu, Mulan runs off the roof, jumping over the hole, which has reappeared.
Continuity mistake: When they are singing 'A girl worth fighting for' look closely at the their chest plates. They change colour from time to time.
