Actress joins fellow Brit for the Alan Turing biopic.

Multiple outlets are reporting that Keira Knightley has entered into talks to star opposite Benedict Cumberbatch in the Morten Tyldum-directed indie ‘The Imitation Game.’

Featuring a Black List script by Graham Moore, the film is based on the life of Alan Turing, one of the 20th century’s greatest minds. A mathematical genius and a pioneer in computer-science, Turing was responsible for the cracking of the German U-boat Enigma cipher in World War II. In 1952, after revealing his homosexuality, he was forced to participate in a humiliating treatment program, and was ever after regarded as a security risk. His suicide in 1954 remains one of the many enigmas in an astonishing life story. No word on Knightley’s role.

The indie project will be produced by Teddy Schwarzman of Black Bear Pictures with Nora Grossman and Ido Ostrowsky of Ampersand Pictures. Moore’s script is adapted from Andrew Hodges’ book ‘Alan Turing: The Enigma.’
