Personal background: previous takes on Oppenheimer and/or the Manhattan Project I've watched or read: at school,
In der Sache J. Robert Oppenheimer by Heiner Kipphardt (docudrama based on the transcripts of the hearings, part of the reading canon as an example of post war German drama),
Fat Man and Little Boy (movie focused on Leslie Groves (Paul Newman) and Oppenheimer (Dwight Schultz), a theatre play on the London stage called Oppenheimer but not really very good, so I don't remember whom it was by, and the
tv series MANHATTAN which got cancelled after two seasons and mostly was smart and fascinating, full of complex (fictional) characters, though I had some serious nitpicks with the second half of the second season. (
Manhattan had Oppenheimer and some of the other historical characters in cameos and brief supporting roles, but the main characters were all fictional scientists and their spouses whom the tv series made part of the project.) So yes, I'm interested, but not enough to have read actual biographies, only the occasional essay.
Oh, and on a related but not identical subject: I have seen, read and listened to Michael Frayn's play
Copenhagen (about Werner Heisenberg, Niels Bohr and Bohr's wife Margarete) a lot.
As for Chistopher Nolan movies: my favourite remains
The Prestige, I haven't watched some (to wit, Memento, Tenet, Interstellar, Dunkirk) and have varying degrees of admiration, interest or annoyance for those I did watch, to wit, his Batman trilogy and
Inception.
With all this in mind, I knew I wanted to see
Oppenheimer in the cinema and not at home a year later, which was definitely the right choice, because say what you want about Nolan, he does use that big screen to the max.
