The Atonement actress is thought to be up for the part of Joan Clarke who worked at Bletchley Park and was briefly engaged to the homosexual Enigma code-breaker
Keira Knightley looks set to join Benedict Cumberbatch in a film based on the life of ground-breaking mathematician and Enigma code-breaker Alan Turing.
The Atonement actress is in talks to play a woman who forms a “complicated relationship” with the code-breaker, according to The Hollywood Reporter.
Although details are yet to be released, it is likely that the part Knightley is being touted for is that of Joan Clarke, Turing’s co-worker in Hut 8 at Bletchley Park, a good friend to whom he proposed marriage in 1941.
Graham Moore's screenplay, The Imitation Game, has been commissioned by Black Bear Pictures with Headhunters with Sherlock star Cumberbatch lined up to play Turing.
Turing, who was gay, apparently told Clarke, also a brilliant mathematician and cryptanalyst, about his sexual preference. But Clarke was “unfazed” by her fiancé’s homosexuality, according to Andrew Hodges’ biography, Alan Turing: The Enigma.
However, Turing decided he could not go through with the marriage and the pair remained good friends until his death.
