Continuity mistake: When Russell Crowe and the other cop are chasing a crook through a hotel room, Crowe gets pinched in a doorway by the crook with the door. The crook starts to bite Crowe's hand, so Crowe signals the other cop to smash the crook's head through the door with a mallet. When the cop does, he uses the handle end, and in the next shot, when he's pulling the mallet out back through the door, it's coming out with the hammer-head end first.
Suggested correction: This is incorrect. The mallet goes through the door handle first, then the door opens and we see the mallet end.
Revealing mistake: Frank pulls up to his buddy's house where he's offered a bribe of a ski chalet. When he gets out of the car there are visible snow flurries. The scene moves to the living room that overlooks a lake. The trees are all lush and green in the background - obviously not winter.
Suggested correction: That was Richie, not Frank, who was offered the bribe.
