Killing Them Softly sounds right up my alley

This is a movie that just got on my radar today with the release of the first teaser poster, which I think looks pretty sweet. Stars Brad Pitt as an enforcer. Check. It's a gangster movie with Ray Liotta. Check. Set in Boston. I'm officially powerless against not seeing this movie. Opens September 21.
                                                          
                                                         Here is the synopsis
Cogan (Brad Pitt) is an enforcer, and when the mob's rules get broken, Cogan is called in to take care of business. This time a high-stakes card game has been held up by an unknown gang of thugs. Calculating, ruthless, businesslike, and with a shrewd sense of other people's weaknesses, Cogan plies his trade, moving among a variety of hoods, hangers-on, and big-timers, tracking those responsible, and returning "law and order" to the lawless Boston underworld.
