As far as teaser trailers go this one for new Brit film, Tinker, Tailor, Soldier, Spy is pretty promising indeed.

The film is an adaption of the 1970s British spy novel by John le Carré and the first teaser trailer (below) looks like the full length film is going to be very impressive. The film stars Colin Firth, Benedict Cumberbatch and Gary Oldman and takes place during the Cold War and follows an ex-spymaster, George Smiley, as he is brought out of retirement to unearth a Soviet spy at the heart of British intelligence agency MI6.

Tinker, Tailor, Soldier, Spy will be released in UK cinemas on 16 September.
