A fantastic new trailer has been unveiled for Oppenheimer, the next feature from filmmaker Christopher Nolan.

The film tells the story of J. Robert Oppenheimer (Cillian Murphy, reuniting with Nolan for the sixth time), the American theoretical physicist who is often credited as the “father of the atomic bomb” for his role in the U.S. Government’s nuclear weapon program known as the Manhattan Project.

The film’s incredible cast includes Emily Blunt as Katherine “Kitty” Oppenheimer, Matt Damon as General Leslie Groves Jr., and Robert Downey, Jr. as U.S. Atomic Energy Commission founding member Lewis Strauss. Also among the line-up: Rami Malek, Florence Pugh, Benny Safdie, Michael Angarano, Josh Hartnett, Dane DeHaan, Matthew Modine, Alden Ehrenreich, and Kenneth Branagh.

A lot of talent behind the scenes as well, including 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).

Nolan directs from his own 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.

Oppenheimer will be in Australian cinemas on July 20th and U.S. release on July 21st.
