I Am Not Your Negro (Dir. Raoul Peck, 2016)
"Using James Baldwin's unfinished final manuscript, Remember This House, this documentary follows the lives and successive assassinations of three of the author's friends, Medgar Evers, Malcolm X and Martin Luther King Jr., delving into the legacy of these iconic figures and narrating historic events using Baldwin's original words and a flood of rich archival material. An up-to-the-minute examination of race in America, this film is a journey into black history that connects the past of the Civil Rights movement to the present of #BlackLivesMatter."
