Richard The Ice Man Kuklinski led a double life beyond anything ever seen on The Sopranos , becoming one of the most notorious professional assassins in American history while hosting neighborhood barbecues in suburban New Jersey. Now, after 240 hours of face-to-face interviews with Kuklinski and his wife and daughters, author Philip Carlo tells his extraordinary story. Kuklinski was Sammy The Bull Gravano's partner in the killing of Paul Castellano at Spark's Steakhouse. John Gotti hired him to kill the neighbor who accidentally ran over his child.

As for possible movie competition, it would work on the level of The Silence of the Lambs .
