Previously overlooked films from Black woman directors are celebrated in a month-long season at the BFI Southbank. Look out for arresting early work from Dee Rees, Amma Asante and Julie Dash in a genre-spanning line-up that takes in everything from coming-of-age dramas (1983's Sugar Cane Alley) to dystopian epics (1995's Welcome II the Terrordome). Expect an eye-opening journey through some of cinema's overlooked but startlingly inventive corners.
