Continuity: In the bamboo forest fight scene, Jin and Mei are pinned down by the bamboo spears and they are surrounded by a field of bamboo stakes. But when all the soldiers that were sitting in the bamboo are shot down by the Flying Dagger members, the stakes suddenly all disappear, and then reappear after all the soldiers have landed.

Continuity: During the last fight, Leo still has a dagger in his back that he is not allowed to remove. This dagger keeps disappearing and reappearing , not to mention that he keeps falling and rolling on his shoulders during the scene, where the dagger should be stuck.

Revealing: When Jin is fighting in the prison, he kicks two guards into the walls of the stone hall. The one on the right of the screen hits the stone wall making it shake and a block move.

Continuity: Right before the final battle, Leo hits Mei with a dagger to the chest. During the ensuing conversation she frequently goes from having a bloody mouth with red teeth, to having a clean mouth with no signs of blood on her teeth.

Continuity: During the "Echo game", Jin throws the full bowl at the targets and all of the shells fall on the floor. Yet in all shots afterward, they are nowhere to be seen.

Factual error: In the scene where Mei is bathing in that small pool, you can see on her arm a the scar from her vaccination. As you might expect, they didn't have these vaccinations in the 1800s.

Other: During the final fight scene between the two protagonists, there is a howling gale which blows snow sideways. yet it never ruffles the protagonists' hair.

Continuity: During the fight in the bamboo forest the soldiers throw many bamboo spears each, but they are never seen carrying more than one at a time. As they show in the movie, it takes a while to make these spears (cut down a stick, trim off the branches and sharpen it), so where did the extra spears come from?

Continuity: There are two scenes in the forest in which Jin is riding away from Mei, but he stops to consider whether he should carry on or return to her. In both of these scenes you will notice that between shots the horse that he is on changes several times.

Continuity: During the final fight scene between the two protagonists, the camera shots flick between POV of Leo looking up at Jin through two crossed swords, and then looking down past Jin at Leo through two parallel swords.
