Whatever inaccuracies there might be in
Hidden Figures, you can watch it knowing that that's the real Katherine Johnson on the screen. That great American, that shining example to us all, that's who you're seeing on the screen.
I detest both
The Imitation Game and
A Beautiful Mind. That wasn't Turing you were seeing up there, and that wasn't Nash you were seeing up there. I think it would be very, very difficult to portray Nash properly on screen, he was the most complicated man imaginable, so I'll give Opie and Crowe a pass. No pass for Benedict Cumberbatch, a totally phony portrayal. Alan Turing was a normal guy, for all practical purposes. From Wikipedia page of TIG:
While a few writers and researchers have tried to assign
such a retrospective diagnosis to Turing,
[108] and it is true that he had his share of eccentricities, the Asperger's-like traits portrayed in the film – social awkwardness, difficulty working co-operatively with others, and tendency to take things too literally – bear little relationship to the actual adult Turing. Despite enjoying working alone, Turing was sociable and had friends, was also viewed as having a sense of humour, and had good working relationships with colleagues.
Well, as soon as I hit Post I'm going onto Amazon and order
Alan Turing: The Enigma, by Andrew Hodges. I have a good collection of biographies of physicists and mathematicians and this will be an excellent addition. Turing: a very great man.
. LionJim gets it. Of course, I don’t get it.
