Continuity mistake: 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.
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.
Continuity mistake: 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 mistake: 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.
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.
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?
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.
Continuity mistake: During Mei's dance at the beginning of the film her dress slips down exposing her shoulder. There's one instant where the shot changes and her dress is back on her shoulder, then it changes back to closeup and it's off again.
