THE CRITERION COLLECTION - Phil Burbank (Cumberbatch) is brutally beguiling. All of Phil's romance, power, and fragility are trapped in the past and in the land: He can castrate a bull calf efficiently; he swims naked in the river, smearing himself with mud. He is a cowboy as raw as his hides. In 1925, the Burbank brothers, wealthy ranchers in Montana, are on their way to market, the brothers meet Rose (Kirsten Dunst), a widowed proprietress, and her son Peter (Kodi Smit-McPhee). Phil is so cruel he drives them both to tears. His brother George (Jesse Plemons) comforts Rose and then returns to marry her. Phil swings between fury and cunning, taunting Rose in an eerie matter. He mocks her son more overtly but then appears to take the boy under his wing. Is this plot twisting further into menace?
