Continuity mistake: When the young Chinese girl is kidnapped, while in the car, her tie is on. When she tries to fight the guy her tie is off in one shot, then back on again a few seconds later. There is also no blood after the first shot, but when the shooter opens the back door, there is blood on Soo Yung's face, but mid fight, the blood is missing, and again blood is present when she runs out.
