Christopher Nolan talks about writing and directing the new film Oppenheimer, about the man who's known as the father of the atom bomb, J. Robert Oppenheimer. Nolan also directed the WWII movie Dunkirk, The Dark Knight, and Inception. The film is about Oppenheimer's leading role in the race to develop the bomb before the Nazis. But after Hiroshima and Nagasaki, he became an arms control advocate, opposed building the hydrogen bomb, and was targeted during the anti-communist witch hunts of the 1950s.
Later, Maureen Corrigan reviews the new novel by James McBride.
