This is one of my favorite exchanges in the movie: The shootout between Ray and Harry:
Ray: Harry, I’ve got an idea.
Ray: My room faces out the canal, right? I’m going to go back to me room, jump into the canal, see if I can swim to the other side and escape.
Harry: All right.
Ray: If you go outside around the corner, you can shoot at me from there and try to get me. That way we’ll leave this lady and her baby out of the whole entire thing.
Harry: You completely promise to jump into the canal? I don’t want to run out there, come back in ten minutes, and find you fucking hiding in a cupboard.
Ray: I completely promise, Harry. I’m not going to risk having another little kid dying on me.
Harry: So, hang on — I go outside and I go which way? Right or left?
Ray: [upset] You go right, don’t you? You can see it from the doorway! It’s a big fucking canal!
Harry: All right. Jesus. I only just got here, haven’t I? Okay, on the count of one, two, three, go. Okay?
Ray: What? Who says it?
Harry: Well you say it.
Marie: You people are crazy.
It’s an inane conversation in an inane situation, hitting that pitch perfect tone which McDonagh manages to do in movie after movie: a combination of violence and humor. These guys are intent on both killing and survival, but approach the shoot out in ridiculous fashion. Marie’s comment reflects what we’re all feeling and is a great capper on the exchange.
