If you’ve been paying attention to any of the previous trailers released for director Tomas Alfredson’s new cinematic adaptation of the acclaimed John le Carré novel Tinker, Tailor, Soldier, Spy, then you’re probably already psyched to check out this sinister spy thriller.

An official clip and TV trailer have been released for the film, which arrives in UK theaters next month. Here in the States, however, we’ll have to wait a little longer than previously expected.

The U.S. release date for Tinker, Tailor, Soldier, Spy has been pushed back to December 9th this year, where it will open against The Sitter and New Year’s Eve – as opposed to The Twilight Saga: Breaking Dawn – Part 1, which it was originally slated to compete with during opening weekend.

Seeing how Alfredson’s followup to Let the Right One In will largely be appealing to a different crowd than those who flock to see R-Rated Jonah Hill comedies or celebrity-crammed rom-coms, it shouldn’t have any effect on the box office returns for the definite awards-contender that is Tinker, Tailor, Soldier Spy.

Gary Oldman’s turn as the shrewd ex-MI6 agent George Smiley is already racking up praise from those who’ve seen Alfredson’s film. Likewise, the rest of the cast (which includes Tom Hardy, Colin Firth, John Hurt, Ciarán Hinds, Benedict Cumberbatch, and Mark Strong) virtually reads as a who’s who of well-respected English actors.

Most of the Tinker, Tailor, Soldier, Spy footage unveiled so far has revolved around Oldman’s investigative character, but this first clip from the film focuses on two other important players: Control (Hurt), the man “at the top of the ‘Circus'” who suspects one of his fellow top MI6 agents of being a Soviet mole – and Jim Prideaux (Strong), a fellow who Control recruits in order to keep an eye on each of his code-named suspects (see: the title).

Fair warning – the following Tinker, Tailor, Soldier, Spy clip (via Empire) contains VERY MILD SPOILERS for anyone not familiar with le Carré’s original novel or its previous screen adaptation. Bear that in mind before you decide whether or not to watch it.

Tinker, Tailor, Soldier, Spy looks to boast some shadowy cinematography, bleak imagery of Cold War-era Europe, nuanced performances, and the sort of mysterious atmosphere that keeps you on the edge of your seat as you wonder exactly what twist or turn the plot is going to take next. In other words: this looks like the sort of smart and calculated spy game that features secret agents doing what they’re supposed to excel at – being discrete and lurking around in dark corners (both literally and metaphorically). A James Bond movie, this is not.

To reiterate: Tinker, Tailor, Soldier Spy is now slated for theatrical release in the U.S. on December 9th, 2011. However, it will open in the UK next month on September 16th.
