Continuity mistake: Natsuo and Tony have just exited the bowling alley. Some residual scuffle happens outside, and one guy with a yellow shirt gets up quite stunned. New shot ("My mistake, cos I don't trust you") and the guy is back rolling on the ground. (01:00:40)
Continuity mistake: Conversation across the car out of the bowling place. Costas sarcastically says "Well, with that kind of hard evidence we should get a conviction overnight" and pulls his hands back to open the door. But in the next shot, the hands are still on the car roof and he changes position only after. (01:01:10)
Continuity mistake: When the two unlikely heroes arrive in front of Scully's place, the sun is just below the postbox in the opening shot, but when they are walking to the door, the whole front is in shadow, the sun being behind the house. (01:02:20)
Continuity mistake: At the precinct after the encounter with Madras, Pat Morita tells Jay Leno "You good cop and honorable man." Behind him, Dingman is seated, arm along the armrest, but when the inspector pops out of the office he is already leaning forward and ready to perform the arrest he ill be ordered a couple seconds later. (01:14:20)
Continuity mistake: At the club where they are eating ribs, Costas at one point says "Oh great" showing a broken toothpick. But the previous image shown was a close-up and he was browsing pictures with that hand. (01:17:15)
Continuity mistake: When Costas picks the photo with the street gang graffiti detail from the print tongs, he holds the picture by the top corner in the close-up, the side in the following shot. Then in another close-up, similar hands and tongs disposition, inconsistent with the frontal views. (01:19:40)
Continuity mistake: During the climactic car chase with Leno on a motorbike, the bike darts down the road along a store, and the villains shoot at him breaking a store window. A store window, singular, because the same window gets shot a couple times, just shown from a different angle. Same for other views of extras/stunt people diving out of the way/falling down, the window bit with the life preservers is the most obvious of course. (01:25:55)
Revealing mistake: At the end of the racetrack scene, the bike stops before the curve where the staff is waving the yellow flag for an accident. In the close-up of the asphalt you can see skidmarks exactly following the path the bike makes, and the odds that the racetrack where F3-like cars are competing has motorbike-sized prints exactly coming out at that curve are of course pretty low. (01:27:20)
Continuity mistake: When Tony is laughing about Natsuo and 'the same flight' as Oshima, his hand is up from the crutch. The policewoman he met early in the movie sits by him next, her hand is on the back of the seat, but at the cut it is not anymore. (01:33:55)
Continuity mistake: During the "exciting" conclusion, Investigator Natsuo runs toward the villain's vehicle, jumps, and kicks through the windshield. Besides the fact that there are some poor special effects at work, watch this quick shot closely. As he is flying through the air in that split second, the villain's car changes colour! It is quite obvious, as the car goes from a dark red color to dull grey.
Other mistake: Watch closely as Investigator Natsuo kicks through the windshield and kicks the villain in the face. The villain's head caves in like it is made of cardboard.
