Five Came Back is a three-part documentary adapted from Mark Harris‘ best-selling book Five Came Back: A Story of Hollywood and the Second World War that focuses on the five filmmakers – John Ford, William Wyler, John Huston, Frank Capra, and George Stevens – who risked their lives during the war to bring the truth back to Americans the only way they knew how: through their work.
