In reality Joan Clarke was recruited by her former academic supervisor, Gordon Welchman, to the Government Code and Cypher School (GC&CS) Exaggerating Turing's social difficulties to the point of depicting him having Asperger syndrome or otherwise being on the autism spectrum. The depiction of the recruitment of Joan Clarke as a result of an examination after solving a crossword puzzle in a newspaper.


In reality, Hilton had no such brother, and decisions about when and whether to use data from Ultra intelligence were made at much higher administrative levels. Showing a scene where the Hut 8 team decides not to use broken codes to stop a German raid on a convoy that the brother of one of the code breakers (Peter Hilton) is serving on, in order to hide the fact they have broken the code. More than 200 British Bombes were built under the supervision of Harold Keen of the British Tabulating Machine Company. A new machine with a different strategy was designed by Turing (with a key contribution from mathematician Gordon Welchman, unmentioned in the film) in 1940. Rejewski designed a machine in 1938 called bomba kryptologiczna which exploited a weakness in German operating procedures that was corrected in 1940. It was a British Bombe machine, which was partly inspired by a design by the Polish cryptanalyst Marian Rejewski. In actuality, this electromechanical machine was called 'Victory' and it was a collaborative, not individual, effort. The following are, in my opinion, some of the more egregious inaccuracies (taken from Wikipedia): Naming the Enigma-breaking machine "Christopher" after Turing's childhood friend and suggesting that Turing was the only cryptographer working on it with others not helping or opposed. Alan Turing's life is interesting enough not to have to resort to making things up.
#WHO BROKE THE ENIGMA CODE MOVIE#
I know many people differ from me, but I am opposed to taking "artistic license" when they're simultaneously presenting the movie as based on a true story. At first I gave it an 8, then I moved it down to 4 when I found out how historically inaccurate it is.
