What a tough proposition - killing your brother to save the other. "The Proposition" (2005) stars Ray Winstone as the rugged vigilante Captain Stanley, who is obsessed with tracking down gunslinger Danny Huston. He's the sadistic, poetry-spouting leader of an outlaw gang that's wreaking havoc in the Outback, circa the late 1800s. His gang includes his two younger brothers, played by Guy Pearce and by Richard Wilson. Early on, the captain captures the younger boys, the brooding Charlie and simple-minded Mike, offering to spare the latter's life if Charlie will track and kill their ruthless older brother. Charlie takes that chance, leading to a date with destiny for all three brothers in this dark Western saga.
