Now that it started shooting, and that a first image has been released, Christopher Nolan’s “Oppenheimer” is set to have rumors swirling around its ultra-secretive 5+ month production.

The film depicts the life of the title character J. Robert Oppenheimer, who had an involvement in WWII’s Manhattan Project, which earned him the moniker of the "father of the atomic bomb.”

Back to the first still released, it was a black-and-white picture of Cillian Murphy as Oppenheimer. According to IndieWire, “Oppenheimer” is the first film to shoot in IMAX black-and-white analog photography. Nolan’s first two films, “Following” and “Memento”, we’re also shot this way, with the latter using it for time-related scenes.

Whether Nolan uses B&W for the whole film remains a mystery, but we can confirm that, at least a few sections of 2023’s “Oppenheimer” are being shot in the format.
