“All Me: The Life and Times of Winfred Rembert,” a documentary directed by Vivian Ducat, won the 2013 Brown Harris Stevens Audience Award at the Hamptons Take 2 Documentary Film Festival, which was held at the Bay Street Theatre in Sag Harbor earlier this month. The film is the story of a self-taught African-American artist who spent seven years on a chain gang in a Georgia prison, where he learned how to tool and dye brightly colored leather canvases.
