Errol Morris has become one of our most celebrated documentary filmmakers, covering offbeat subjects like a pet cemetery, a swamp town in Florida and Stephen Hawking’s views of physics. His investigation of a Texas murder case, The Thin Blue Line, is credited with overturning the conviction of death-row inmate.  His most recent film, The Fog of War: Eleven Lessons from the Life of Robert McNamara, won the Academy Award in 2004.
