Fabulous ! Utterly fabulous ! There should be a number of Oscars coming out of this including one for best male actor - possibly the best performance in cinematic history. I was so moved by it that I couldn't speak for ten minutes afterwards and had to leave the cinema fast. I've read all of Hawking's books (many times) and had never thought of him as a healthy young man. The closing sequence is merciless. See it on the big screen if you can - not because it needs it, but because it thoroughly deserves it.
