In Bruges

In Bruges, starring Colin Farrell and Brendan Gleeson, tells of two hit men spending some time in Bruges in order to lay low after a hit went wrong, well that's at least what they are first told. The film reveals that Ray ( Colin Farrell) had killed a child while on a job and now his best friend was tasked with taking his life, but he cannot go through with it. And so his boss Harry, played by Ralph Fiennes, has to go to Bruges to deal with them both.
The film has the feel of a small, independant movie, the script is engaging and incredibly funny, and Colin Farrell plays probably the best role I've seen him in to date. Here's a clip showing the style of comedy used in the film, in one of the best shootouts I have ever seen:
