Armando Iannucci is one of the great unsung heroes of modern British comedy, at least on this side of the Atlantic, and I hope that the buzz success of "In The Loop" starts to change that.  If you sit through this film and say at the end of it, "But no one really talks like that, and if they did, there's no way other professional people would put up with it," then I envy you your sheltered existence, and I wish the world worked the way you think it does.  I have met many Malcolm Tuckers in my day, and Peter Capaldi gives such perfect, savage life to the character that you might be excused for thinking it's really who he is.  This spin-off from the British comedy series "In The Thick Of It" may be set against the world of politics, but it could easily be set inside a billion-dollar corporation or a Hollywood studio.  The point is that almost all power is a by-product of fear, and the people who are the most powerful are also those who are almost overwhelmed by a deep and yawning panic about their place in the world.  It is an ugly mirror that this movie holds up to us, but a hilarious one all the same.
