Christopher Nolan announced the production of 'Oppenheimer,' marking his first film not distributed by Warner Bros. Pictures since 'Memento' (2000), due to conflicts over the studio's simultaneous theatrical and HBO Max release schedule.

Cillian Murphy was the first cast member to join the project, with other notable actors such as Robert Downey Jr., Emily Blunt, Matt Damon, Florence Pugh, Josh Hartnett, Casey Affleck, Rami Malek, and Kenneth Branagh joining the ensemble cast over the following months.

Pre-production for the film began, setting the stage for the extensive and detailed preparation characteristic of Nolan's projects.

Filming took place, utilizing a combination of IMAX 65 mm and 65 mm large-format film, including scenes in IMAX black-and-white film photography for the first time. The production emphasized extensive practical effects with minimal compositing.

The post-production phase involved meticulous editing and the integration of the film's unique visual elements, including the alternation between color and black-and-white scenes to convey different perspectives on Oppenheimer's life.

The film 'Oppenheimer' was released, offering a biographical drama that explores the complex life of J. Robert Oppenheimer, his scientific achievements, and the moral and ethical implications of his work.

Upon its release, the film received critical acclaim for its portrayal of Oppenheimer's life, the performances of the cast, and Nolan's direction. The film also sparked discussions about the moral and historical context of the atomic bomb's development.
