A new film of Tinker, Tailor, Soldier, Spy is due to be released in September: starring Gary Oldman as George Smiley, with Colin Firth, John Hurt, Ciaran Hinds, Mark Strong, Benedict Cumberbatch and Tom Hardy, directed by Tomas Alfredson (Let the Right One In) - how could it go wrong?
Here's how:
Right, so, you'll have noticed that's the trailer for Captain America: The First Avenger rather than Tinker, Tailor... The key moment comes around 1:51, when the Red Skull informs Steve Rogers that "Captain, we are much alike."
Now here's the trailer for the new Tinker, Tailor:
If you're in a rush, it's at 0:51: Oldman, as Smiley, telling someone (Karla, perhaps) "We are not so very different, you and I."
Compare this:
Or compare Belloq, the wicked Frenchman in Raiders of the Lost Ark, telling Indiana Jones, "You and I are very much alike. Archeology is our religion, yet we have both fallen from the pure faith. Our methods have not differed as much as you pretend. I am but a shadowy reflection of you. It would take only a nudge to make you like me..."
There is a usefulish discussion at tvtropes. This isn't the worst of the new Tinker, Tailor's sins, though: you'll notice that elsewhere in the trailer somebody takes the trouble to say that "Things aren't always what they seem", which I would guess is something they point out to you quite early on at spy school.
You can keep your fancy foreign cocktails. I'll stick with my Guinness:
