But the film doesn't end there. There's about another hour of the film after that point, dealing with Oppenheimer's crushing, halluncinatory guilt at what he has unleashed, and the hellish ordeal of the vindictive McCarthyist investigation into his security clearance at the behest of Lewis Strauss (after Oppenheimer clashed with him by trying to stop development on the H-bomb, opposing a nuclear arms race, personally humiliating Strauss in the process of doing so). Strauss's subsequent downfall at the Senate confirmation hearing that denied him a place in Eisenhower's government also takes place after this, as well as (most devastatingly) the final scene with Einstein that really brings the hammer down on the drama with a sobering, emotionally devastating finale.

Did you leave the screening early and miss all of that?
