Continuity mistake: In a moment during the fight scene between Ninja Christie and the cop playing billiards, she kicks him into a wall. His hand is raised in one shot but not in the next. (00:38:20)
Continuity mistake: In the sequence where Hanjuro crashes the helicopter, the pilot disappears and reappears at random. (00:09:15)
Suggested correction: Actually no; he's still there even in the camera angle the second screenshot is from; the knee of the policeman that is fighting Hanjuro covers his head, and then the seat makes it impossible to see him again. You may have to slo-mo to spot it, but he's visible at the beginning of the shot.
Continuity mistake: During the golf course opening scene, a motorcycle cop gets kicked to the ground by the ninja swinging from a grappling hook. In the next shot, the cop somehow falls into the water hazard along with his motorcycle. (00:07:28)
