Earlier today, the London Film Festival set The Imitation Game as its opening-night gala. We now have a trailer courtesy of The Weinstein Co — which paid a whopping $7M for the Morten Tyldum-directed movie at the Berlin EFM in February. Benedict Cumberbatch stars in the story of Alan Turing, the genius British mathematician, logician, cryptologist and computer scientist who led the charge to crack the German Enigma Code that helped the Allies win World War II. Winston Churchill said Turing’s was the single biggest contribution to Allied victory, but the brilliant scientist was later prosecuted by the UK government in 1952 for homosexual acts which the country deemed illegal. He died two years later and was just granted a posthumous pardon by the Queen in December last year. The film centers on Turing and his team’s race against time to break the Enigma code at Britain’s top-secret Bletchley Park facility. Graham Moore wrote the script. Keira Knightley, Matthew Goode, Mark Strong, Rory Kinnear, Charles Dance, Allen Leech and Matthew Beard also star. Weinstein will release in the awards-season corridor on November 21; Studiocanal releases a week earlier in the UK.
