Jason Clarke and Louise Lombard are the latest to join Christopher Nolan's ensemble cast for biopic film Oppenheimer, starring Cillian Murphy.

Jason Clarke and Louise Lombard join a stacked ensemble led by Cillian Murphy that also includes Emily Blunt, Florence Pugh, Robert Downey Jr., Matt Damon, Rami Malek, Benny Safdie, Josh Hartnett, Dane DeHaan, Jack Quaid, Matthew Modine, Dylan Arnold, David Krumholtz, Alden Ehrenreich, Michael Angarano, David Dastmalchian and Jason Clarke, as previously announced.

Nolan's casts are always stacked, each addition often more exciting than the last. "Oppenheimer" has been steadily gaining talent over the last several months.

In Nolan’s latest, which is based on the Pulitzer Prize-winning book American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer by Kai Bird and the late Martin J. Sherwin, Murphy plays the theoretical physicist of the same name, whose work on the Manhattan Project led to the invention of the atomic bomb. The epic thrusts audiences into the pulse-pounding paradox of the enigmatic man who must risk destroying the world in order to save it.

Nolan is directing from his own script, and is producing alongside Emma Thomas and Atlas Entertainment’s Charles Roven. The film is slated to debut in theaters on July 21, 2023.
