But inaccurate in the specifics (eg, the Bombe, the machine depicted, was not Turing complete, and if you were to stretch the definition of "computer" to what Bombes could do, it was far from the first), and bitterly insulting in its likely omission of many of the other figures involved (especially the Poles).
I'm looking forward to it.
It could be worse: the last time Hollywood took a crack at this story ("Enigma"), they invented a mathematician, gave him Turing's accomplishments, but made him not gay, and the only Pole on screen was a baddie.
I don't have particularly high hopes for this one, though. I don't find CumberTuring's performance in the trailer engaging- he's playing Generic Cumberbatch Character #9. Keira Knightley just looks like Keira Knightley, not a woman in 1943.
...except for the text in the trailer @ 1:19-1:21 that says "They had to create the world's first computer."
Another book worth reading is David Kahn's historical account 'Seizing the Enigma.'
