Rather than auditioning people for roles, Jay Giannone hand picked the cast based on the background of each character.
Kevin Weeks (Danny "Duke" Dugan) is the boss of the neighborhood in this movie. In real life, he is a reputed gangster of the criminal organization of James J. (Whitey) Bulger, according to the Boston Herald, Boston Globe and many other publications worldwide.
Kevin Weeks is the author of the N.Y. Times Best Seller "Brutal", which is an autobiographical story of his life inside the Irish mob.
