Continuity mistake: During the big fight scene at the end of the movie, both Nick and Sato become totally saturated and covered in mud. Nick defeats Sato, and is shown to have immediately arrested Sato and brought him to the police station. It is clear they came directly to the station from the fight, yet there is now hardly any mud on either of them.
Continuity mistake: Near the end, when Michael Douglas has convinced the Yakuza boss to let him tag along to that meet of Oyabun's out at the farm, they drive down this dirt road, then kick Douglas out of the car. After doing so, he's standing there a little ways away from the car. A henchmen throws him a shotgun with a modified handle. We see it land at his feet, with the trigger side facing the camera. It cuts to a shot of his face, and he reaches down to pick up the shot gun, and the camera pans down and we see right before he picks it up that the trigger was now facing him before he put his hand on it.Stormsigma
Continuity mistake: Right before Sato decapitates Charlie, he looks back from his motorcycle at Nick and draws his Sword, holding it up with the blade pointing slightly upwards. From the angle behind him,he lowers the blade and then in the corresponding front angle, he immediately lowers the blade again.
Continuity mistake: At the very end of the film, the antagonist who had previously sliced his pinky off in a ritual has magically grown it back.
