I have trouble seeing any movie as good history.
I was very disturbed watching the movie.
We’re venturing into “SOCIAL” territory here as opposed to understanding speech in movies. It would be a lot of preparation to see the movie, but two excellent, very long Pulitzer Prize-winning books are The Making of the Atomic Bomb by Richard Rhodes (won General Non-Fiction Pulitzer) and American Prometheus by Martin Sherwin and Kai Bird (Biography Pulitzer). The first book is one of the best books I have ever read. It’s the whole enchilada of the historical events in Europe and developments in 20th-century physics that led to the making of the atomic bomb and its use and examines the background of many of the scientists involved in making the bomb. Rhodes explains everything about the Manhattan Project, including the nuclear physics, in very clear layman’s terms. The scientists making the bomb weren’t naive; they knew it would be a terrible weapon but were driven by desperation in what they saw as a race against the Nazis to make it. They thought it would make war unthinkable, and there would have to be a world government, at least for nuclear arms, to control the future possibility of nuclear armageddon. We didn’t quite make it there, but at least we have SALT and nuclear non-proliferation treaties that most of the world follows.
Having read both books, I thought Christopher Nolan condensed an incredible amount of stuff, almost all accurately, into a very short time frame. My wife has read neither book, and she said without me gossiping to her about Oppenheimer’s life as I read American Prometheus, she would have had a tough time understanding exactly what was going on in the movie. I would think it would be even harder for a hearing-impaired person who doesn’t have excellent corrected word recognition. It might spoil the movie, but reading the Wikipedia entries for the film or either of the books, instead of the very long books themselves, might help you understand the film more, especially if you are severely hearing impaired and likely to miss key dialog in key scenes.
The very final scene in the movie wasn’t historically accurate, but it was so beautifully and artistically done. The whole way Nolan built up the drama and led the viewer back to that scene depicted earlier in the movie was totally awesome. We’re all Prometheans now, at least regarding the possibility of being tortured by the gods for our release of knowledge.
