The story of Alan Turing and his role in breaking the Nazis' Enigma code in World War II has been told many times. But never has Britain's lauded mathematician been reincarnated as such a socially offensive, harsh and humorless character.

"My own concern was bringing the character back to life as he very likely was — warts and all," says Benedict Cumberbatch, the award-winning actor who plays Turing in "The Imitation Game."

To Cumberbatch, this wasn't about taking creative liberties, but opening up to the layers and challenges surrounding Turing.
