Christopher Nolan wrote and directed the new film "Oppenheimer", focusing on Robert Oppenheimer, the "father of the atomic bomb" played by Cillian Murphy. The audience will see how a mysterious man fell into a paradoxical dilemma: in order to save the world, he must first destroy it. Adapted from the biography of Robert Oppenheimer, "American Prometheus: The Triumph and Tragedy of Robert Oppenheimer" by Kay Bird and Martin J. Sherwin, which won the 2005 Pulitzer Prize for Biography.
