Robin Wright’s directorial debut “Land” finds a successful Chicago woman leaving her life behind after a horrifying tragedy for a solitary existence in the mountains of Wyoming. Wright said it came to her at a time when mass shootings seemed to be happening every other week and this story of loss and healing resonated with her. She cast Oscar-nominated Mexican American actor Demián Bichir opposite her, as the kind soul Miguel who helps Wright’s Edee survive. He’d experienced his own devastating loss a few months before shooting, but found the process to be therapeutic. “Land,” a Focus Features release,” opens in theaters Friday.
