The already awesome cast of Christopher Nolan's next movie, Oppenheimer, just got even better.
According to The Hollywood Reporter, Florence Pugh and Rami Malek have signed up for roles in the biographical drama, which will explore the development of the atomic bomb during World War II.
Cillian Murphy has already been cast as J. Robert Oppenheimer, a leading theoretical physicist who spearheaded the Manhattan Project, a research and development initiative that created the first nuclear weapons. Emily Blunt, Robert Downey Jr., and Matt Damon have already signed up for roles in the movie, too.
Pugh will portray Jean Tatlock, a prominent psychiatrist whose affair with Oppenheimer concerned the U.S. government because she was a member of the Communist Party. 
Malek will play an unnamed scientist, while another new cast member, Benny Safdie, has been cast as Edward Teller, a Hungarian scientist who was also an integral part of the Manhattan Project.
The movie, scheduled for release in July 2023, is based on the Pulitzer Prize-winning book American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer by Kai Bird and Martin J. Sherwin. 
It's being described by Universal as an "epic thriller that thrusts audiences into the pulse-pounding paradox of the enigmatic man who must risk destroying the world in order to save it." Nolan’s last movie, the sci-fi thriller Tenet, came out in summer 2020.
