Tinker Tailor Soldier Spy Character Posters Revealed

The Imp Awards (via Dark Horizons) has revealed three new character posters for Tomas Alfredson's Tinker, Tailor, Soldier, Spy. I'm still partial to the Smiley one that debuted last month, but I do like the code theme. The choice of characters strikes me as odd, though, unless they're going to do one for everyone. (Ricki Tarr? Really?) But why not just do the four main suspects with the Tinker, Tailor codenames? Pictured above is the (presumably final) UK quad poster for the film.
