An Eminently Well-Made Biopic
Brilliant adaptation of the story of Bletchley Park and the cryptanalysis team, ran by Alan Turing, that cracked the code of the German Enigma Machine during World War II. Featuring an outstanding starring performance from Benedict Cumberbatch as war hero Turning and supporting acts from a brilliant cast including Keira Knightley, Charles Dance and Mark Strong, 'The Imitation Game' is a powerful and eminently well-made biopic that illuminates the facts whilst respecting the story it is based upon. The English-language debut of 'Headhunters' director Morten Tyldum, this British World War II thriller is a highly conventional story about humanity that creates a fascinating character, anchored by a hypnotically complex performance.

Did You Know?


One of the dancers at the Engagement Party is a distant relative of the real Alan Turing.


Alan Turing: Are you paying attention? Good. If you're not listening carefully you will miss things. Important things. I will not pause, I will not repeat myself, and you will not interrupt me. If you think that because you're sitting where you are and I am ...


Alan Turing's team calls him out, saying they are the only ones who have been making any progress. His team mentions that they used letter frequency analysis to break some of the transmissions; however, letter frequency analysis is an attack that works well on substitution ciphers but wouldn't have worked well on the Enigma. Letter frequency analysis works by analyzing the frequency of letters in a language, as well as the frequency of letters in a cipher text. You then replace the cipher text letters with the corresponding language letter as ranked by frequency. If the newly generated plaintext is not fully decrypted, a person can usually find the errors easily. This attack would not work well on the Enigma, as it was not a simple substitution cipher. The rotors would click forward one position for each letter entered; therefore, the key was, in part, based on the position of the letter in the plaintext. Typing the same letter consecutively would return a different cipher letter for each iteration of the letter, because the key for letter n is related to letter n-1.
