> chose to make the RDJ villain central to the plot
The movie is really about the conflict between a small-souled bureaucrat and a physics genius. The question is: what could a different story have been? I'm not sure there is enough juice in the "personal guilt" angle, and I don't think the "communist spie" angle is viable in today's Hollywood, given the general political leanings and, well, who the actual traitors were. Oppenheimer's direct involvement hasn't been conclusively proven (unlike eg Leo Szilard and a myriad others), so it comes down to how much you believe Pavel Sudoplatov's testimony, who was an NKVD general.
