Roughly ten months after the airing of Women of the Movement, a six-part ABC miniseries about the horrific 1955 murder of Emmett Till and the relentless pursuit of justice by his mother, Mamie Till Mobley, Chinonye Chukwu’s Till  (Orion, 10.7), a theatrical feature that apparently tells a similar story, will debut at the 60th New York Film Festival.
