I managed to squeak in a 3rd movie for the weekend [damn that felt good] and it was "In Bruges". What I read was that it had a sense of humor and was an action flick. But I don't think that does the movie justice. The humor is wickedly dark, from writer/director Martin McDonagh [the guy who wrote all those terrifically fucked up Irish plays "Beauty Queen of Leenane", "A Skull in Connemara", etc...] and the action is a slow build but has you chewing your nails in joyous agony.
Think "Shallow Grave"...
I think the American trailer went too far and gave too much of the film away...and I think it gives the wrong tone of the film. So, have a go at the German language version the trailer. Woo hoo!
