Continuity mistake: When Kasumi is holding her sword at the throat of the purple haired girl at the start, her sword changes between shots. In the first shot, the blade is facing up. In the next, it is now flat. Not enough time has passed in between shots for this to have occurred.
Continuity mistake: When Tina Armstrong kicks the two pirates off the yacht, she then adopts a classic fighting stance for the pirate leader. In the first shot she's leading with her left arm; in the next shot she's leading with her right arm. Not enough time has elapsed for this to occur.
