Continuity mistake: When Clay fights Anisette at the gas station, her heels change from stilettos to flats. Best visible when Clay throws her on a car, right after she says he should be retired.
Factual error: The movie is set in the US, but there are several things which aren't found in the US that give away the fact that it was shot in the UK. In one scene, a Tesco superstore can be seen in the background and the lift bridge seen in the film is Kings Ferry Bridge which connects the Isle of Sheppey to the Kent mainland.
