Factual error: The movie is supposed to be set in South Carolina and shows license plates on the front of cars. But cars in South Carolina don't have license plates on the front.
Continuity mistake: In the scene where John is talking to Van Buren underneath the bar, John has a large spot on his neck, as well as a scab and red mark on his chin. These aren't present at another point in the film. (01:05:25)
Continuity mistake: As John and his wife drive along the ocean, the position of her seat belt changes from scene to scene. At times it's close to her neck and other closer to her chest.
Continuity mistake: Right after the gas station explosion scene we see Triton follow the truck in the police patrol car. During the scene we see that the patrol car gets repeatedly shot down the whole right side; including the front right tire being shot out as Triton approaches the truck on the left side. A few moments later right before both the truck and patrol car are about to make the jump we see that the patrol car has no bullet holes on the front right side anymore; and the tire is still intact.
Revealing mistake: Watch carefully after Angela is thrown through the windshield of the bus. There is a shot of diamonds and blood-stained glass scattering on the floor. But in reality, there is a shot of plain diamonds falling and the bloody glass is faded in during the middle of the shot. Most visible on the edges of the screen, where the pieces emerge from nowhere.
Factual error: South Carolina Highway Patrol does not use the decal that is on the door like the one of the patrol cars that pulls up to the gas station.
Continuity mistake: After John wrecks the police car and comes out of the woods, he talks to the detective. He has what appears to be a small cut under his left eye, later that changes to a blemish. It changes positions through out the movie.
Factual error: The movie is supposed to be set in South Carolina. John and his wife are shown driving along the ocean side and driving on a very hilly roadside. South Carolina does not have that type of coast line.
Continuity mistake: In the scene where Triton is tied up by the local hunters, who think he is a cop, his knife is thrown into a wall by one of the other characters. Triton is never seen picking it up or grabbing it. Yet, in the next cut Triton is running through the woods (after escaping) and he now has the knife.
Revealing mistake: Although the police Camaro has ABS (for Anti-lock Braking System) moulded into the brake pedal rubber, they must have disconnected this system for dramatic effect, so that John could lock the wheels and smoke the tyres under heavy braking.
Character mistake: On the refrigerator is a letter from the Department of Defence - Defense is misspelled.
