Her celebrated photograph The Migrant Mother is one of the most recognized and arresting images in the world, a haunting portrait that came to represent the suffering of the Great Depression. Yet few know the story of the woman who created the portrait: Dorothea Lange. Directed and narrated by Lange’s granddaughter Dyanna Taylor, herself an award-winning filmmaker, Grab a Hunk of Lightning explores the uncompromising vision of the woman behind the camera, whose enduring images document five turbulent decades of history: striking workers, destitute migrants fleeing the ravaged Dust Bowl, Japanese Americans forced into internment camps. Taylor combines intimate family memories and journals with extensive scholarship and never-before-seen footage to bring Lange’s life and work, triumphs and pain, into sharp focus.
