Interesting, and i will for sure watch it.
I think though that Turing's role will be overdone by Cumberbatch, as far as i read Alan T. was not very self assured, let alone boasting about his mathematical capabilities.
Also as far as i read, the 'bomb' and the other machine constructed, were not able to instantly decypher the messages. Still took one - two days. Important for the war effort, but not enough to divert a convoy instantly, after some boat breaking radio silence with the Tabu.
And a tête-à-tête with Mrs Clarke ? Hmm.
Looking forward to it anyyway
