Margaret Brown’s documentary work examines the American South, from a seminal film on Townes Van Zandt “Be Here to Love Me,” to the impactful story of the BP oil spill’s lasting impact “The Great Invisible,” which won the Grand Jury Prize at SXSW a few years ago. Her film “The Order of Myths,” which examined Brown’s native Mobile, Alabama and its still segregated Mardi Gras celebration, won numerous awards including a Peabody and the Truer Than Fiction Independent Spirit Award. She’s also done short form work for the New York Times and Field of Vision, and recently directed an episode of “Dirty Money” for Netflix.
