Revealing mistake: In the final racing scene, when Dominic's car hits the truck and flips in the air, you can clearly see the stunt driver's helmet as the car turns in the air.
Continuity mistake: In the opening hijack scene, the semi obviously has two sets of rear wheels on the trailer, but when it comes to the scene where the black Honda is under the trailer, there is only one set of rear wheels.
Continuity mistake: After Dom parks his car in the garage after the first race, and walks outside, the cop car that comes down the hill is a Ford Crown Victoria. When the cop car turns around in the middle of the street it's a Chevy Caprice. Easiest way to spot the difference? First car has wide lights, the second one doesn't.
Continuity mistake: There is a scene near the end of the movie, where the hero is chasing the two guys on motorcycles that just shot his friend. At one point, first the motorcycles, and then the car leap over a hill on the street. You can clearly see two ramps at the top of the hill, one for each motorcycle.
Continuity mistake: At the end of the opening credits when the freight is being placed on the truck, you can see the large support beam that goes across. In the next shot when the civic goes under the car, the support beam is gone.
Visible crew/equipment: At the end of the third act, when Diesel and Walker line up at the lights to drag the quarter mile beside the train tracks, you'll notice the reflection of two crew members appear in the back of the side view mirror of the Charger as they approach it to get the steadicam close-up of Diesel telling Walker that on green, he's going for it.
Continuity mistake: After the street race at the start, Leon alerts everyone that the cops are coming. While everyone is scattering you see a closeup of Brian running around to the door of his car and opening it, then a bird's eye view of his car with no-one near it. Then you see other people running and getting into their cars, then you see Brian run up to his car, open the door again and get in.
Continuity mistake: During the final hijacking scene, Dom pulls in front of the truck so Vince can get pull out the passenger side windshield with his harpoon gun. However, if you look closely right before Vince shoots his gun for the first time, you can see that the passenger side windshield is not even there. The glare coming off of the driver side windshield makes it very easy to see the difference between the two.
