The Cillian Murphy-starring film about the ‘father of the atomic bomb’ has the story with the ‘highest stakes’ for a movie since it deals with the ‘survival of the world.’ Christopher Nolan calls his upcoming OPPENHEIMER film the ultimate blockbuster as it deals with the “survival of the world.” The 52-year-old THE DARK KNIGHT director’s upcoming movie stars Cillian Murphy, 47, as “father of the atomic bomb” J. Robert Oppenheimer, and the filmmaker said he has ever dealt with more important story.
