The Butcher (2009) on Netflix

Plot summary

After his boxing career ended, Merle Hench went to work for Murdoch, who runs a San Fernando mob outfit. He has broken heads and collected debts for him ever since, work that gives him little pleasure, and he gambles on a losing streak that has lasted two decades. Around the outfit he is the calm one, soft spoken, known as the Butcher, a nickname the men treat as a joke. Murdoch now considers him expendable, and a heist worth millions from a rival boss needs a man to take the fall. The trap set for Merle fails, and he comes away with a share of the money and with Jackie.
