"Anyone going to a movie, any movie, expecting anything other than fiction is already in the wrong place."
True. Turns out the right place is a cruise ship on its way to La Palma last September, where I attended a factually accurate lecture about Turing given by a bloke who works at Bletchley Park, and <ENGAGE NAMEDROP MODE> I sat right by the real-true-life-and-not-in-a-film Stephen Hawking. I was in nerd heaven.
