Continuity mistake: At the end of the movie where Xander's tanning at Bora Bora, notice that his tattoos are brighter. They have a just re-applied look.
Continuity mistake: After the Prague cop shoots at Vin Diesel and Yorgi, when they are in the garage, they chase him in the GTO. You see Diesel skid the car to a stop to shoot the cop, but when the camera pulls away, you see the car skid another couple of inches after it had clearly stopped before. (00:49:35)
Continuity mistake: During the test when they infiltrate the drug lord's camp and X escapes. In one scene before he leaves the barn/building to go outside and get the bike you see him get up and lean against the door twice. Once to get up and look outside to see one of the copters blow up a truck then it cuts to a reverse angle and you see him get up again to lean against the door.
Continuity mistake: In the beginning, when Xander steals the corvette, he goes into a reverse 180. When the camera angle is switched to camera 2, he's clearly coming out of a power slide (i.e. fishtail). (00:06:20)
Continuity mistake: After Xander's car jumps off the bridge, you can see in one shot that he is jumping from the car. In the following shot, Xander is opening his parachute and jumps off the car. (00:08:40)
Continuity mistake: Just after X gets his new GTO and the cop knocks the window of the warehouse out, X and the bad guy jump back into the GTO. They drive out of the warehouse and the car is dirty on the bottom. If the car was spotless in the previous shot indoors, how did the car get so dirty so fast?
Continuity mistake: Asia Argento unties Xander with a knife she had strapped to her boots. In close-up, the boots are army-like with a dark olive color, but when she was sitting down, and even better when she later has to put her feet on the car pedals, she is sporting pointy camel-yellow boots. (01:35:30 - 01:45:40)
Continuity mistake: Some potato carts are blocking the road. We see the accident spot and there are several people by the carts taking care of the injured driver, with very few potatoes on the asphalt. When Yelena fires the rockets, no people are by the carts anymore, and as they drive through the flaming wreckage there are many more potatoes - of course since the cart just exploded, but they are all perfectly still and not burnt, not looking at all like they come from a cart that blew up in an inferno of flames a split second before. (01:44:20)
Continuity mistake: Yorgi turns towards Yelena when it's time to admit her for the first time inside the secret basement and starts talking; At "Through this door..." his arms are down, but in the next shot when he finishes the sentence he's leaning on it with his left arm completely raised.
