Revealing mistake: When Kar is fighting the bad guy on the roof, the guy holds him up by the throat supposedly choking him, but if you look closely, you can see that he is holding Kar under the chin, not choking him. (00:58:00)
Revealing mistake: At the end when the Monk With No Name has turned old and is walking away from Kar and Jade while waving to them (without looking back), you can see a finger on the left side of the screen covering up the corner and side of the lens. This is for sure in the wide-screen DVD version. (01:37:25)
