Cillian Murphy as Oppenheimer

Nolan’s biopic of J. Robert Oppenheimer has a giant ball of fire in the background as a figure of one of the fathers of the atomic bomb, played by Cillia Murphy, appears beneath the tag line: “The World Forever Changes.”

Stellar Cast

The Universal feature has a stellar ensemble: Kenneth Branagh, Michael Angarano, Robert Downey Jr., Matt Damon, Emily Blunt, Florence Pugh, Rami Malek, Benny Safdie, Josh Hartnett, Dane DeHaan, Jack Quaid and Matthew Modine.

Murphy portrays Oppenheimer, who helped developed the A-bomb during the Second World War, only later to have his loyalty to the US questioned by hawkish government officials.

Oppenheimer is based on the 2005 Pulitzer Prize-winning book American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer by Kai Bird and the late Martin J. Sherwin. Universal won a bidding war for the project, Nolan’s first movie in years not made with his longtime studio home, Warner Bros.

Oppenheimer was shot on Imax 65mm and 65mm large-format film, for which Nolan hired photographer Hoyte van Hoytema, who worked with on Tenet, Dunkirk and Interstellar, and editor Jennifer Lame and composer Ludwig Göransson, who both also worked on Tenet.

July 21: Chris Nolan Fave Date
