Reading the screenplay, I'm once again reminded how impressive it is just how effectively Nolan managed to compress Oppenheimer's life into a ~200 page script, although the large number of exposition dumps between characters combined with the use of the hearings as framing devices definitely helped in that. Plus I was finally able to understand a few lines I hadn't before (like Oppenheimer talking to Pash about "intermediate people," which I thought was him stumbling over the word "intermediary"). And it's also curious to note that the minor errors in timeline were in the original script (Garrison saying the 1943 conversation with Pash was twelve years before the 1954 hearings, Oppenheimer saying the 1949 radioisotopes hearing was six years before the hearings, things like that). It was interesting seeing differences between the screenplay and the final film, like what lines of dialogue were cut in editing. I'm fine with seeing most of them go, I think, but there were a few in particular that I'd have liked to see in the film, like Einstein's historically accurate remark that Oppenheimer loved a woman that didn't love him: the United States government (Strauss and Kitty both connect the hearings to Oppenheimer's supposed guilt, so Einstein's comment would have been an interesting way to connect the hearings to his womanizing). Then David Hill's testimony is lengthened, and specifically helps to answer a question others have asked online, namely how he knew about Strauss' orchestration of the hearings in the context of the film's portrayal of Strauss as the 'twist villain': "I think when all of the evidence is viewed, it becomes highly plausible that the Oppenheimer matter was initiated and carried out largely through the animus of Lewis Strauss" (emphasis mine). And Strauss' excellent monologue where he rants against Oppenheimer is also lengthened, although his meaning is still fairly clear in the film regardless.
