Continuity mistake: In the scene where Sean is making his first pickup for Han, from the large man in the jacuzzi, he is dressed in only a towel. When the large man throws him out of the establishment, he is fully dressed. Are we to believe that the large, angered man who Sean just demanded money from, gave him time to get fully dressed before throwing him out? Or that the large man dressed Sean before throwing him out? Neither of these scenarios make sense.
Continuity mistake: When Sean Boswell is driving the red Lancer for the first time at the docks, right after the guy in the orange sweater says, "Will someone please teach this guy to drift", Sean crashes the back of his car against a pile of wood, and you can see the spoiler falling on the ground. In the next shot, you see Sean's face, and in the background the spoiler is back on the car.
Continuity mistake: In the school canteen scene when Sean is talking to Twinkie for the first time, the food on Sean's chopsticks and the position of them alternates from being in his mouth to back out or on the table between shots, even though Sean is visible in each shot. Also if you watch his drink he takes a sip and puts the glass down, but in the next shot a second later he is drinking from it again.
Continuity mistake: In the final race when the 350Z rear ends the Shelby and rides up on the embankment, as it starts to come back down the right headlight falls out (left one broke when he hit him). In the next scene it is miraculously back in place.
Continuity mistake: At the end of the movie, right before the race against Vin Diesel, the two cars are placed very close, within a foot or two of each other. A couple of shots later, right before the girlfriend says 'Go.', the cars are a couple of feet further apart, even though they haven't yet started the race.
Visible crew/equipment: In the first race with Sean and the rich kid in the red viper are racing each other the rich kid pulls up to the black ute that is following them and yells "whoooo" and puts his fist up, you can see the camera mounted on the side of the viper through the reflection of the black ute.
