Broken Codes, Both Strategic and Social

                     ‘The Imitation Game’ Stars Benedict Cumberbatch

 “The Imitation Game” is a highly conventional movie about a profoundly unusual man. This is not entirely a bad thing. Alan Turing’s tragically shortened life — he was 41 when he died in 1954 — is a complex and fascinating story, bristling with ideas and present-day implications, and it benefits from the streamlined structure and accessible presentation of modern prestige cinema. The science is not too difficult, the emotions are clear and emphatic, and the truth of history is respected just enough to make room for tidy and engrossing dramaAll of this is a lot for a single movie to take in, and “The Imitation Game,” directed by Morten Tyldum from a script by Graham Moore, prunes and compresses a narrative laid out most comprehensively in Andrew Hodges’s scrupulous and enthralling 1983 biography. The film interweaves three decisive periods in Turing’s life, using his interrogation by a Manchester detective (Rory Kinnear) as a framing device. Turing tells the investigator — who thinks he is after a Soviet spy rather than a gay man — about what he did during the war. Later, there are flashbacks to Turing’s school days, where he discovered the joys of cryptography and fell in love with a slightly older boy named Christopher Morcom.

The adult Turing is played by Benedict Cumberbatch (his younger self is Alex Lawther), expanding his repertoire of socially awkward intellectual prodigies, real and fictional. What has made Mr. Cumberbatch so effective as Sherlock Holmes and Julian Assange — and what makes his Alan Turing one of the year’s finest pieces of screen acting — is his curious ability to suggest cold detachment and acute sensitivity at the same time. If he did not exist, 21st-century popular culture would have to invent him: a sentient robot, an empathetic space alien, a warm-blooded salamander with crazysex appeal.

His Turing, whom the film seems to place somewhere on the autism spectrum, is as socially awkward as he is intellectually agile. He can perceive patterns invisible to others but also finds himself stranded in the desert of the literal. Jokes fly over his head, sarcasm does not register, and when one of his colleagues says, “We’re going to get some lunch,” Turing hears a trivial statement of fact rather than a friendly invitation.
