This month we're paying tribute to her Majesty Queen Elizabeth II by she-watching a "crime thriller" about her finest intelligence agents, starring many of her finest subjects. Tinker Tailor Soldier Spy is a criminally underrated (by award ceremonies) film adaptation of the John le Carre novel which rewards re-watching both for the fabulous performances and for the impeccable 1970s decor and hairdos. To paraphrase Kathy Burke's character, I don't know about you, but Tomas Alfredson and Gary Oldman must be feeling seriously under-Oscared!
