Errol Morris is a celebrated documentarian whose films have covered an array of topics in law and national security. They include "The Fog of War," which won an Oscar for its account of Robert McNamara's role in and lessons from the Vietnam War, and "The Unknown Known," which told the story of the political career of Defense Secretary Donald Rumsfeld. Morris most recently directed "American Dharma," a documentary profile of former Trump strategist Steve Bannon. Earlier this year, Morris sat down with Jack Goldsmith for a conversation about those three films. They talked about what interested Morris about McNamara, Rumsfeld, and Bannon; why Morris believed each of them agreed to be interviewed by him; and much more.
