Without using any visual effects, Christopher Nolan re-creates the first nuclear bomb explosion.

To make his next film “Oppenheimer,” director Christopher Nolan recreated the first nuclear bomb detonation without computer-generated imagery.

Think of Christopher Nolan’s Tenet’s real 747 sequence, The Dark Knight‘s truck flip, or Interstellar’s spacecraft settings with starry exteriors projected outside the windows instead of the customary bluescreen. The director’s forthcoming film, Oppenheimer, which is about the man who made substantial contributions to the development of the atomic bomb, has provided him with additional opportunity to work on talking-point scenes that do not rely on computer-generated imagery (CGI).

Christopher Nolan, the director of “Oppenheimer,” has disclosed that during the filming of his newest film, he recreated the first nuclear bomb detonation without the use of any computer-generated imagery (CGI) effects. The movie is based on nuclear scientist J. Robert Oppenheimer, who was the director of the Manhattan Project and is consequently widely acknowledged as the “father of the atomic bomb.” The film is based on his life. according to variety

The film takes place over a long length of time, considered to be at least a decade. As a result, Nolan chose to revisit some of his early work to influence the way his current epic would be filmed, including his preferred method of filming: IMAX. This meant teaming up with Hoyte van Hoytema, his trusty cinematographer with whom he has collaborated since Interstellar, to solve a fresh difficulty.

Memento was shot on 35mm anamorphic film, but after filming first-of-their-kind action scenes on The Dark Knight with IMAX cameras, the filmmaker has made the large-format film a go-to, with all of his big movies being shot on the ultimate cinematic format. The issue for Nolan, at least on Oppenheimer, was that no one had ever shot in large-format monochrome before, so some inventiveness was necessary. Oppenheimer will be released in theatres on July 21, 2023.
