Based on the novel Caste: The Origins of Our Discontents and the life of its author Isabel Wilkerson, Origin is a new biographical drama written and directed by Ava Duvernay. Weaving together history and the personal life of the author, the movie explores the common root all forms of societal oppression share. The film features When They See Us star Aunjanue Ellis-Taylor as Isabel, King Richard's Jon Bernthal as her husband Brett, and Selma's Niecy Nash as her cousin Marion.
