I was under the impression that Oppenheimer was going to be shot entirely in black and white. Now, Nolan has made statements that the approach will be closer to Memento, which used black and white extensively; but, was mostly color.
Still, Oppenheimer will be the first movie to have been shot on large format black and white. This did require a massive collaborative effort from the filmmakers, Kodak, and Fotokem.
A lot of people put in a lot of work to do their parts to see a creative vision come to life and push limits.
It's just that none of them work for Disney.
