There are at least two stories within “The Imitation Game” that, by themselves, would make for gripping films. There is Alan Turing the maths genius (the English add an ‘s’ to math, for some reason), and there is Alan Turing the closeted homosexual, in a country where being gay is illegal. Since it is difficult to secure funding for any movie, the obvious choice, of course, is to combine these two massive plots to make one hell of a film. There are times when the two stories get in the way of one another, but thanks to a cracking script and superb performances by Benedict Cumberbatch and Keira Knightley, “The Imitation Game” gives “A Beautiful Mind” a run for its money in the “damaged genius period piece” genre, assuming there is such a thing.
World War II is in full swing, and Alan Turing (Cumberbatch), a Cambridge maths professor, applies for a job with the British military because they need code breakers, and Turing is convinced that he is the brightest mind they will ever find. Despite bombing the interview in spectacular fashion, Turing is recruited to join a team of math geniuses. Their task: break the Enigma code, the German encryption tool that is sent out on open airwaves but is so complex that no one has been able to solve it. (Turing’s team even has an Enigma machine, but the code is so dense that it is of no use.) Turing pulls some unpopular moves to put himself in charge of the group, but eventually earns the group’s respect. His commanding officer (Charles Dance), however, needs results, and because of the aforementioned bad interview, he’s looking for a reason to shut Turing’s program down. In comes plucky Joan Clarke (Knightley), who has the misfortune of being a female good at maths. Turing, naturally, bonds with her instantly, since they are both outcasts. Turing and Clarke do amazing things together, and just when they think it’s time to celebrate, that is when they realize that they have a whole new set of decisions to make, and they are far more difficult than the previous set of problems that faced them.
