Continuity mistake: After Jet Li has arrived in France and has left the cab, he is walking up a road which seems like China Town to find the shop with dragon in the window. As he arrives near the shop a prostitute with a long black jacket and red hair is standing and talking to a man wearing jeans. Then Jet looks at the picture and then at the dragon, the camera angle changes and as Jet is about to walk in you see the same woman standing against the wall and the man has done the Jet Li vanishing act.
Question: Is it really possible to stop blood flowing from the brain with a pin stuck in the neck? Also, why does the blood not flow again after Jet Li has removed the pin?
