Since he slammed the door of Warner, Christopher Nolan wants to show that he does not depend on a studio to continue to dazzle us. While he joined the Universal team, which spent $100 million to finance the filmmaker’s new project, the latter is gradually building up an XXL cast for his first foray into the biopic genre. It started with Cillian Murphy , who had landed the title role of Robert Oppenheimer, the “father of the atomic bomb”, and the arrival of Emily Blunt in the production to play the hero’s wife. Then it was the turn of Matt Damon, Robert Downey Jr. and Josh Hartnett to join the team. We found the cast already quite complete, but it was to misunderstand the guy. Florence Pugh, Rami Malek and Benny Safdie then joined the project, playing Jean Tatlock, a member of the Communist Party who had an affair with Oppenheimer, a scientist and Edward Teller, a Hungarian physicist known for creating the bomb. hydrogen and be a member of the Manhattan Project.Today, Collider tells us that actor and director Kenneth Branagh, who has already worked with Nolan on Dunkirk and Tenet, is joining the dream team in an as yet unknown role.To teaser this future project large-scale, a first image of Cillian Murphy, in black and white and with a cigarette in his mouth, as usual, has just been unveiled by the studios. The script for this thriller centered on the researcher who invented the atomic bomb is written by Christopher Nolan himself and is particularly ambitious. The director was inspired by the biography of J. Robert Oppenheimer, American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer, signed by Kai Bird and Martin J. Sherwin, who received the Pulitzer Prize in 2006 after 25 years of work. The filmmaker will shoot part of the film in Imax from the beginning of 2022, for a release scheduled for July 21, 2023 in American theaters. He will find Hoyte van Hoytema, director of photography for Interstellar, Dunkirk and Tenet, as well as editor Jennifer Lame (who worked on Tenet) and composer Ludwig Göransson (known for the music of Black Panther, and who signed that from Tenet).
