When Broker is being dunked in the water, the blood from his head wound keeps disappearing and reappearing between shots.
When Gator is talking on his cellphone in the lab, one shot shows him with his gas mask around his neck, and the next shot shows him with it on his forehead.
When Broker hugs Maddy on the bridge at the end of the movie, his hand has no bruises although he just fought Bodine.
During the final chase the offside tail-light on Gator's 4 x 4 alternates between working and not working between scenes.
@ around 1 hour 29 minutes when Broker is in the police cruiser and turns round in Gator's yard to start chasing him the blue and red lights on top of the vehicle are flashing as Broker starts to turn, but then when you cut to the overhead shot they are not switched on then when Broker has turned round the lights on top of the vehicle are switched back on again.
It's established that the film takes place in Louisiana. In Louisiana, the surname "Bodine" is pronounced as "Bodeen" not "Bodyne" as everyone in the movie pronounces it.
After fighting the gangsters Phil doesn't pay for the gas.
While Morgan 'Gator' Bodine is cooking up methamphetamine with his partner, neither character has the filters attached to his mask.
Clancy Brown's character is credited as "Sheriff Keith Rodrigue" but his uniform's name plate says "Rodriguez."
The shotgun Broker grabs appears to be a Benelli M4 12 gauge, a semi-auto shotgun (obvious by the way Broker loads it by pulling the charging handle on the side of the receiver). Yet every time Broker fires the shotgun, the sound of someone racking the slide of a pump action shotgun is audible.
