As a filmmaker, Christopher Nolan loves examining themes like morality, identity, and the destructive power of the human psyche. It makes sense that he'd tell a story about theoretical physicist J. Robert Oppenheimer, whose life has largely been defined by his work on the Manhattan Project and iconic "I am become Death" quote. Oppenheimer explores the man behind that quote.
