'Till' Director Chinonye Chukwu

Till tells the story of Mamie Till-Mobley, whose decision to hold an open-casket funeral for her murdered son served as a catalyst for the civil rights movement. "Without Mamie Till-Mobley, the world wouldn't know who Emmett Till was," director Chinonye Chukwu says. "She wanted the world to witness what happened to her child so then this can stop happening to other Black children and Black people."
