There are two stories going on simultaneously; because there’s the dog’s version, which you can’t really trust, and then the real version, I suppose. So I had to figure out a way to juxtapose those images. That all came together. I decided to do the dog’s fantasy in black and white for a couple of reasons. One is that his vision of things is so dark and it’s like a film noir, a very grim vision and overly dramatic. So that lent itself to the black and white. I also heard that dogs actually see in black and white, so it seemed like it worked that way.
