Tinker Tailor Soldier Spy (2011)
If a season of 24 took place in the smoky, well-tailored underground of British intelligence circa 1973, it might look a little like this precision-made John le Carré adaptation from Let the Right One In director Tomas Alfredson. Even if you can't follow terse and tightly-woven mystery, the search for Soviet mole led by retired operative George Smiley (Gary Oldman), the ice-cold frames and stellar cast will suck you into the intrigue. It's very possible Oldman, Colin Firth, Tom Hardy, John Hurt, Toby Jones, Mark Strong, and Benedict Cumberbatch are reading pages of the British phone book, but egad, it's absorbing. A movie that rewards your full concentration.
