I recently watched the Errol Morris documentary The Fog of War: Eleven Lessons from the Life of Robert S. McNamara (IMDB). I highly recommend it; it’s probably the best documentary I’ve ever seen. I went from knowing nothing about McNamara to having considerable respect for him.
all of morris’ films, except “thin blue line”, are highly recommended by moi. tbl was just sort of boring to me but maybe it would be better after a second viewing.
