I realise it has been discussed here but I will add a couple thoughts on Oppenheimer which I saw last night. Will try to avoid spoilers.
Very good film biopic of him and the Manhattan Program IMO. The first 15 minutes I felt were a bit unstructured but the journey did help explain the brilliance and world view of the individual which would be a key factor in the rest of the film. That Tatlock storyline although weird in some ways just reinforced the ambiguous nature of Oppenheimers' beliefs (not ambivalent, just ambiguous) and there was a parallel there with the bomb I felt.
For a biopic like this I feel Nolan did a great job between the scene selection, cuts, and importantly the sound to maintain a tension and anxiety all thru the 3 hours. Very few lulls because there was always something to maintain tension and I felt that was very, very well done.
Casting was impressive and it was fun to see so many faces but who were not there as a spiff, but to play out the character and did so very well. hats off to Oldman for once again being a chameleon in the Truman shots, and same for Branagh and Conti for their roles. Really felt like everyone took the job seriously and tried to play the characters.
Cillian should be up for an Oscar for this one IMO as it was a great piece of acting and his ability to flip back and forth between the scientific interest, personal ego, and ambiguity of remorse was close to an acting masterclass. Nolan with the whole team balanced that out to a tee and that adds a lot of depth to the story reinforced with a few callouts along the way about "at that time", "when it happened", etc.. when people years later were trying to superimpose their then current standards and beliefs. Talk about a much needed wake up call where being right today doesn't necessarily mean it was wrong yesterday - ambiguity without ambivalence at it's best.
