If you're a mystery fan, and there's a little bit of one in each of us, get on the Tinker, Tailor, Soldier, Spy bandwagon. Gary Oldman leads a superb cast (including Colin Firth and Tom Hardy, to name two people that you think are awesome) in a game of Clue. Who among this group of men is the one (we know there's one, just check the latest trailer!) up to no good. The stakes: espionage. The accents: British. The result: cinematic dynamite.
To begin code cracking, look deep into Gary Oldman's unblinking eyes (it helps that he's a photo). There are clues hidden throughout the crowd of figures lining the Oldman gaze... to further investigate, look at the equally encoded posters of Firth and Hardy.
