Good movie but story not true.

True Enigma code crackers were Jerzy Różycki, Marian Rejewski, Henryk Zygalski. They were Polish mathematicians and did that as early as of 1933 then handed over their discovery to British and French. Rejewski reconstructed Enigma machine that Polish intelligence intercepted. Zygalski made perforated sheets also known as Zygalski sheets required to reverse engineer Enigmas settings. Finally Różycki was the person who found mathematical methods to crack the code, first so called cyclometer for earlier Enigma version, later cryptographic bomb for new Enigma version (wrongly attributed to Alan Turing). There was a condition, after WWII British were obliged to acknowledge, who made the discovery. British scientist do so but English language mass media denies this fact for pure gain, and for sake of sales in this movie's case.
