Universal Pictures has unveiled the first official trailer for Oppenheimer, the highly anticipated twelfth film from Christopher Nolan (Inception, The Dark Knight, Interstellar).

The film stars Cillian Murphy as American theoretical physicist J. Robert Oppenheimer, the man credited with being the “father of the atomic bomb” for his key role in developing the first nuclear weapons.

A hugely impressive cast here, including Emily Blunt as Oppenheimer’s wife, biologist and botanist Katherine “Kitty” Oppenheimer; Matt Damon as General Leslie Groves Jr., director of the Manhattan Project (the name given to the research and development project); Robert Downey Jr. as Lewis Strauss, a founding commissioner of the U.S. Atomic Energy Commission; Florence Pugh as psychiatrist Jean Tatlock; Benny Safdie as theoretical physicist Edward Teller; Michael Angarano as Robert Serber; and Josh Hartnett as pioneering American nuclear scientist Ernest Lawrence. And that’s not all. Also on board are Rami Malek, Kenneth Branagh, DaneDehaan, Matthew Modine, and Alden Ehrenreich, among others.

Nolan wrote the screenplay, an adaptation of the Pulitzer Prize-winning book American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer by Kai Bird and the late Martin J. Sherwin.

The film reunites Nolan with Interstellar, Dunkirk and Tenet cinematographer Hoyte Van Hoytema; Tenet editor Jennifer Lame (Hereditary, Manchester by the Sea); and Tenet composer Ludwig Göransson (Black Panther, Creed). Oppenheimer was shot using a combination of IMAX 65mm and 65mm large-format film photography and included, for the first time ever, sections filmed using IMAX black and white analogue photography.

Oppenheimer is lined up for Australian release on July 20th and U.S. release on July 21st, 2023.
