Following up on the Imitiation Game, if you want a film about the most amazing person, try Oliver Sacks, his Own Life. It's a similar story, but much of it is told by Sacks himself. Very affecting because he faced the same struggles and had many of the same reactions trans people do to being trans, although in his case, he was gay like Turing.
The way Sacks tells the story is very open and affecting. His mother rejected him when he came out and he went through a period of hypergendering, as many of us do. It's driven by almost the same motivations in gay people when it happens, although not quite.
I cheekily invited Sacks to a student led medical society and to my astonishment he came and proved to be as inspiring as John Bowlby. Both helped change my life. Sacks was a medical hero at the time and well known because of Awakenings and The Man Who Mistook His Wife for a Hat, but in person he was like meeting a six foot plus capacitor on full charge. Magnetic, but modest and he comes over as he was in the film, which is neat.
