Oppenheimer served as the director of the Los Alamos Laboratory during World War II, and is often credited as the "father of the atomic bomb" for his role in the Manhattan Project, the research and development undertaking that created the world's first-ever nuclear weapons.
This is a story rife with controversies and drama, which takes on nobody less than the man who ushered in a new level of war, whether he wanted it or not. Christopher Nolan wrote the film with Cillian Murphy in mind for the lead. Even though he has excelled as Tommy Shelby in ‘Peaky Blinders,’ carrying a major movie for the first time is a responsibility he takes very seriously, and has made a stunning job of it.
Nolan has commented on a unique aspect of the film where parts are presented in colour and others in black & white. "I wrote the script in the first person, which I'd never done before. I don't know if anyone has ever done that, or if that's a thing people do or not… The film is objective and subjective. The colour scenes are subjective; the black-and-white scenes are objective. I wrote the colour scenes from the first person.”
The incredible cast includes Florence Pugh, Matt Damon, Cillian Murphy, Emily Blunt, Robert Downey Jr., Gustaf Skarsgård, Gary Oldman, Josh Hartnett, Kenneth Branagh, Rami Malek and Casey Affleck.
