In the Loop (2009)

In the Loop is a crass parody of international relations between Britain and the United States. There are plenty of noteworthy quips, but most of them are not-repeatable. It's fast moving, cynical and quite smart. You won't come away from the film inspired, but you may have laughed depending on your attitude towards vulgarity (the best lines reference hobbits though, so you might be OK).
