I enjoyed Christopher Nolan's "Oppenheimer" very much. Announcing the film caused a general stir among the movie-going public. This was a subject they were very hungry for. I think, in some sense, what people wanted from the film, and the film they actually got might be two different things, and this disconnect between expectations might diminish the film's longevity.
Much like what you see in the film, people's main concern before Hiroshima was that, once the bomb became hypothetically possible, it was imperative that the Americans develop it first. Whatever implications there might be in creating such a device, the only one that mattered was that we do it first. Keeping in mind that the German team had the universally recognized world's greatest physicist, Werner Heisenberg, leading their team, the concern that the Americans might be second or third to develop such a weapon had serious implications for the history of the world.
After Little Boy was detonated some 600 meters above Hiroshima, and Fat Man, hours later, above Nagasaki, the world's opinion, including our own, about the nature and implication of atomic weapons changed. If you look at the cinema after the war, doubts about the bomb were making clear inroads into our subconscious. In the United States, movies started featuring ants made gigantic after exposure to the bomb began eating farmers. The bomb reanimated monsters of the past. In Japan, the Bikini bomb revived and mutated a dinosaur, covering it in burned and scarred flesh like the survivors of Hiroshima, and began burning and destroying what parts of Tokyo survived the war.
Audiences expected Nolan's film to address these issues. We've been discussing them since the war. Even in the eighties, Sting wrote a song about how to protect his little boy from Oppenheimer's deadly toy. The film we got included a lot of that, but it included a lot more of how Lewis Strauss used the panic caused by J. Edgar Hoover and Joseph McCarthy to try and ruin Oppenheimer's life.
While that's an interesting story, I don't think most people even knew it ever happened, and if they did, they were still much more interested in the bomb itself than attempts to discredit Oppenheimer afterward, although I think it's important that we discuss the fact that the move to discredit and ruin Oppenheimer had more to do with things that ultimately didn't really matter, especially compared to what Oppenheimer actually did.
There are lots of movies about McCarthy and Hoover. I think it's important to tell that story. I think it's more important to tell the story of telling everything involved in unlocking some of the secrets of the universe. I'm not really that interested in some parts of the story that Noland chose to tell. I've been aware for some time that Oppenheimer had a reputation as a womanizer. Florence Pugh's presence in the film was interesting, but you never really got to know much about her; other than that, she was pretty unstable psychologically. I've been in love with psychologically unstable women. There's always a reason for it, but in this film, we don't see it, and ultimately Tatlock's life, suffering, and death don't make much difference in the final impact of Oppenheimer's life.
In some ways, I still prefer Roland Joffé's 1989 film Fat Man and Little Boy. It doesn't have the visual style of Noland's Oppenheimer, but it deals a lot more with the science behind the project and a lot more discussion of the moral implications. Roger Ebert hated it, and Rotton Tomatoes gives it a pretty lackluster score, but I still think there's something to the film.
