Richard Kuklinski was a hitman for a branch of the New Jersey mob up through the 1980s, though he also had a sideline in killing for his own pursuits or just plain kicks. In one of the more obvious casting choices ever, Michael Shannon plays Kuklinski as a stone-faced monolith in The Iceman, a film that might be based on true events but feels as false as a dozen other mob flick knockoffs (complete with energetic but wasted Ray Liotta performance) from the past couple decades.
The Iceman is playing now, here and there. My review is at Film Racket.
