Legendary neurologist and author Oliver Sacks (Awakenings; The Man Who Mistook his Wife for a Hat) shares the intimate details of his battles with drug addiction, homophobia, and a medical establishment resistant to his work in this illuminating documentary by Ric Burns. Sacks was a fearless explorer of unknown mental worlds who helped redefine our understanding of the brain and mind, the diversity of human experience, and our shared humanity. A month after receiving a fatal diagnosis, Sacks sat down for a series of filmed interviews in his apartment in New York City. For eighty hours, surrounded by family, friends, and notebooks from six decades of thinking and writing about the brain, he talked about his life and work, his abiding sense of wonder at the natural world, and the place of human beings within it. Drawing on these deeply personal reflections, as well as nearly two dozen interviews with close friends, family members, colleagues and patients, and archival material from every point in his life, this film is the story of a beloved doctor and writer who redefined our understanding of the brain and mind.
