William Kunstler was one of the most famous lawyers of the 20th century. The New York Times called him "the most hated and most loved lawyer in America." His clients included Martin Luther King Jr., Malcolm X, Phillip and Daniel Berrigan, Abbie Hoffman, H. Rap Brown, Stokely Carmichael, Adam Clayton Powell, Jr., and Leonard Peltier. In Disturbing the Universe: Radical Lawyer William Kunstler, filmmakers Emily Kunstler and Sarah Kunstler explore their father's life, from middle-class family man, to movement lawyer, to "the most hated lawyer in America."
