Three trailers for Tinker Tailor Soldier Spy. Top to bottom: the incredibly taut, mysterious and darkly thrilling UK teaser trailer, my personal favourite; the less teasing yet no less thrilling UK theatrical trailer and finally, below, the US ‘blow-by-blow-the-whole-story-with-sign-posts’ trailer. I don’t really understand. I’ve met plenty of Americans and none of them have been so completely stupid as to need the simpleton trailer that they’ve got. The fact is, the film in the first two trailers, looks far more enticing than that in the third. Or is it just me?
