I really enjoyed watching the movie, however left the cinema disappointed! Fantastic story, great Alan Turing - pioneer of computer science. BUT - German military texts enciphered on the Enigma machine were first broken by the Polish Cipher Bureau, beginning in December 1932. This success was a result of efforts by three Polish cryptologists, Marian Rejewski, Jerzy Różycki and Henryk Zygalski, working for Polish military intelligence. Alan devised a number of techniques for breaking German ciphers, including improvements to the pre-war Polish bombe method. Shame Polish Intelligence was omitted in the movie.
