Director Dee Rees discusses her new film, Mudbound, with fellow Director Mira Nair. The film tells an epic story of two families -- one black and one white -- who are forced to confront the realities of life in the American South. Though pitted against one another by a ruthless social hierarchy and bound together by the shared farmland of the Mississippi Delta, the families' lives are changed when sons from both families forge an uneasy friendship over their shared experience during World War II.
