imitation game movie

I have, and I also have extensively studied both WWII codebreaking, and Turing's life and work. It's an OK movie, but as any kind of historical thing - fuhgeddaboutit. There are so many 'errors' (changes) that it's basically impossible to list them all. They ran about about one error/change per minute, throughout the whole movie. It's more wrong than right, actually. About the only thing that was absolutley accurate (other than the basic concept, that Turing worked at BP and helped break German codes) was Joan Clarke's soliloquy in his flat at the end of the movie, describing his contribution to the world. Hmm. The descriptions I've seen of their manufacture (e.g. Gordon Welchman, "The Hut Six Story", pp. 138-141, Hugh Sebag-Montefiore, "Enigma: The Battle for the Code", pp. 56-58) all indicate that the machines were manufactured by British Tabulating Machines in their Letchworth factory (about half-way between BP and Cambridge), and only came to BP once they were completed. There was a lot of local sub-contracting of small sub-assemblies which didn't require machining, though (see Welchman). Noel
