What 2023 biographical film about J. Robert Oppenheimer did Nolan direct?

The 2023 biographical film about J. Robert Oppenheimer that Christopher Nolan directed is Oppenheimer. The film follows the American theoretical physicist's role in developing the first atomic weapons during World War II and examines the political consequences that followed.

Oppenheimer stars Cillian Murphy as the title character, with Emily Blunt, Matt Damon, Robert Downey Jr., Florence Pugh, and others in major roles. Nolan wrote and directed the film, adapting it from Kai Bird and Martin J. Sherwin's biography American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer.

Much of the story centers on the Manhattan Project at Los Alamos, where Oppenheimer led a team of scientists working to build an atomic bomb before Nazi Germany could do so. The narrative also explores his later security hearing and the loss of his political influence during the early Cold War.

The film is sometimes described simply as a historical drama, but its official genre is commonly identified as a biographical thriller. Citizen Kane, A Beautiful Mind, and The Imitation Game are also biographical or historically focused films, but none is Nolan's 2023 Oppenheimer film.
