Rome: Would you mind shooting this guy?
Goon: What does it look like we're doing?
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.
During the scene when John is chasing down Rome and his crew just after they have kidnapped his wife, one of Rome's crew is shooting at John and crew says "He's like the Terminator" and the camera shows a shot of Rome lifting an eyebrow in the rear view mirrow. This is a reference to the massive hit Terminator 2 where Rome (Robert Patrick) plays the evil Terminator who just keeps on coming.
