Continuity mistake: When Jack is strangling Donald at the end of the film, take a look at the blood that is on Donald's head. It disappears for a while and then it's there again. (01:22:20)
Continuity mistake: At the end of the film we see Jack have a fight with Donald. Then Jack says " If thats the best you've got, I'm just going to have to kill you". Then Jack grabs Donald around the neck with both hands, but when the camera changes to behind Donald, Jacks hands are not around Donald's neck. (01:22:20)
Continuity mistake: At the end of the picture, why are there fire trucks there with fire hoses laying in the street? There was no fire, just shootings.
Other mistake: At the scene of Coles' ex wife's murder, the police car nearest the footpath is impossibly parked. There is a lamppost inches from the front of the car and a tree inches from the rear. Did it parachute in?
