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.
Continuity mistake: At the car show, Costas approaches the female host reading the specification of the new vehicle. He flashes her badge and tries his usual pickup line. During the sequence, people with recognizable clothes pass behind him, and they never carry from one view to the next, they just disappear at the cut. (00:53:10)
Plot hole: The odd couple tails the suspicious guy bossing around the car company mogul and run a check on the license plate. The response is "Car registered H.W. Scully. No known residence, only address PO Box 25047 Detroit." They tail him a bit, end up in the bowling alley and lose him in the commotion. After that, Leno asks his buddy at the district if he has "anything on that guy Scully", and the answer is "This guy has done anything but rape Bambi. Several weapons charges, assault and battery, he beat a murder rap in Sarasota" etc. And of course, an address. (00:56:35 - 01:01:35)
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: 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: 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)
Continuity mistake: Costas tells the agent that the mysterious person must have gotten out at the mezzanine.The clothing cart meanwhile passes, and its path crosses with a boy with an azure shirt. Wider shot follows, and the guy is still cutting into the path of the clothes valet, but he is in front of the hotel staffer by a significant margin. (00:22:30)
Continuity mistake: Chasing the Japanese detective, Jay Leno enters a mall. He approaches the photo shop hiding his face behind a small balloon, and walks towards the camera. Before the cut, two women move in frame, one wears pink, the other wears blue. Next shot and as he speaks with the girl at the counter the two women are again moving in frame, but they are behind him and starting off from a part of the mall they originally came from. (00:31:25)
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 Costas gets pulled over at the beginning of the movie, he stops the car. Initially, between the brick building and the concrete one there's a road with no cars. In Jay Leno's close-up once he is asked "License and registration, please" behind his big head you can see a black and white car, and a couple police officers on the sidewalk. (00:05:00)
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)
Other mistake: The motor company executive angrily shows to the villainous Madras the newspaper bearing news of the dead Japanese. The date is Friday 19 June. But the day of the final confrontation a couple days later, as shown in a panning view of the racetrack screen, is June 18. (00:34:55 - 01:20:55)
Continuity mistake: During the introduction to the press of the 'Starburst' car, Derek Jarryd pushes a button and the curtain rises; it rises well above his shoulders, but in the close-up he is turning around for the camera and the curtain is just then below his breast pocket level. (00:34:15)
