Continuity mistake: 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.
Other mistake: 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 mistake: 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.
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.
Continuity mistake: 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?Twotall
Continuity mistake: 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.
