Continuity mistake: There is a scene early in the film where the garage explodes. A view from high up shows the explosion. Later in the film when Jim and Frank are on the rooftop, you get practically the same view but look at the area where the explosion was earlier. Everything is perfectly normal and there is NO sign of any explosion.

Continuity mistake: When "Mr Bridges" attacks Jim at Jim's parents home, after Mark kills "Mr Bridges" look at his left arm. (He's wearing a watch on the left wrist.) There is not a single bit of blood and no bite wound. A few shots later, there is lots of blood and a very large bite wound. (00:27:45)
