Revealing mistake: When the SUV flips you can see the fuel tank has been removed for the stunt. (00:51:30)
Revealing mistake: When the car reverses to act as a ramp to get rid of the SWAT vehicles, the one that flips over shows the slide plate used to make the stunt possible. (00:51:30)
Revealing mistake: When the SWAT SUV is flipped, it lands on its wheels and is hit by the second SUV. However, all the SWAT team are no longer in the SUV. (00:51:40)
Factual error: After the SWAT vehicles are disposed of, there's a shot of the front of the car, and there are scrape marks. As cool as it looked, being that is a Corvette, there is no way that it could happen. This is due to the car body being made of basically fiberglass, and couldn't support the weight of another vehicle. Also, the body would be trashed after the impact, therefore the engine destroyed, and not drivable. (00:51:40)
Suggested correction: Would be the case with a regular C6 or Z06, the ZR1 is carbon fibre instead of fiberglass.
Revealing mistake: When we see Jerry's desk you can see the phone is not plugged in. (00:52:50)
Other mistake: When the driver of the ZR1 corvette changes gears the emergency brake lever is visibly up. (00:53:00 - 00:53:55)
Continuity mistake: Just after Cortez got rid of the SWAT vehicles there is a shot from the back of the car driving away from the carnage. The white licence plate with "ZR1" on it (shown earlier) is now missing. (00:53:45)
Continuity mistake: When Dinkem tells Ray he can handle the gun, his hands are up. When the camera cuts his hands are down. (00:58:20)
Continuity mistake: When gearing up for Cortez's arrival, Ray has got a leather jacket on. When they leave to get in the trucks, the jacket has disappeared. (00:59:00)
Continuity mistake: Dinkem starts to cut the pole down and does so with the blade cutting horizontal. Camera changes and now he is cutting at an angle. (01:02:15)
Continuity mistake: When Lewis first saws the telephone pole, it falls over to about a 35° angle and the cable attached to the building ends up being HORIZONTAL to the roof and road, but the telephone cable is DIAGONAL (about 45° upwards) when Lewis climbs the pole. (01:05:15 - 01:06:24)
Revealing mistake: When Owens is shooting Vicky from the school bus, the feed into Vicky is full of blanks. (01:10:00)
Continuity mistake: When Ray dives through the Diner doors, he lands with his arms outstretched. When the camera cuts his arms are under him. (01:12:10)
Continuity mistake: In the field chase scene, the Camaro's driver side mirror is ripped off when the Corvette rams it sideways. It remains off for several shots, then it returns by scene end and stays on through the movie's end. (01:20:10)
Revealing mistake: When driving through the corn fields, it's obvious from the ZR1 wing mirror that the car isn't actually moving. (01:21:35)
Continuity mistake: When Ray drives through the fields, the headrests inside the Camaro ZL1 show SS instead of ZL1. (01:22:10)
Factual error: The southern Arizona border is shown as a river/canyon when in reality it is a straight line through the desert. (01:25:15)
Revealing mistake: When Gabriel Cortez reaches the bridge at the end, he sees Arnold standing there waiting for him. It's blatantly obvious in this shot that all he is looking at is a rear projection backdrop of Arnold and the background. (01:25:40)
Character mistake: Lewis Dinkum tells Deputy Mike Figuerola it's only a .50 cal round that hit him in the shoulder. The rifle he was shot with was a Blaser R93 LRS2 which fires a 338 Lapua round. A .50 pretty much would have torn him in half. (01:33:20)
Other mistake: If you peel out in a cornfield, you will not move, just sit and spin until the wheels are suspended. That's why you see dual-wheel tractors out there; they don't sink into topsoil like regular tractors and road vehicles.
