I received an email from a person who worked on the tech crew of “Oppenheimer.” They elaborated further on what we might expect from Christopher Nolan’s upcoming “bomb” movie.
Suffice to say, the way the story is told is ambitious enough to make it sound very much like a Christopher Nolan movie. This person compared the narrative structure to “Dunkirk.” The film is separated between two timelines. Not always linear or made obviously clear.
The black and white scenes take place after the detonation of the bomb. It tackles Oppenheimer’s public tribunal, if you will, the public humiliation and the after-effects of what he created. Not to mention, the accusations of his being called a communist.
The scenes in color are flashbacks, when Oppenheimer studied and then started helping the US build a nuclear bomb and the inevitable detonation of it. Rumors are that Hiroshima will not be featured in the film, but only the actual test detonation which will last a few minutes.
