"If somebody asks me about the themes of something I'm working on, I never have any idea what the themes are. . . . Somebody tells me the themes later. I sort of try to avoid developing themes. I want to just keep it a little bit more abstract. But then, what ends up happening is, they say, 'Well, I see a lot here that you did before, and it's connected to this other movie you did,' and . . . that almost seems like something I don't quite choose. It chooses me."
