During World War Two, British mathematician Alan Turing played a key role in cracking Nazi Germany’s notorious Enigma code. But soon after, the same man who helped the Allies to win the war would be persecuted for his homosexuality, with harrowing consequences.

Starring Benedict Cumberbatch as Turing with an exceptional performance by co-star Keira Knightley, the film won the People’s Choice Award for Best Film at the Toronto International Film Festival. It’s also earned seven Oscar nominations, including Best Picture, Best Actor, Best Supporting Actress, Directing, plus nine BAFTA nominations.
