I kept thinking and talking to Chris [Nolan] about what I thought the Batman character was. If there was an arc to be had, it was that he sees his parents getting killed – that’s the defining moment of his life – and he feels guilty for it. The theme is interrupted at essentially two notes: it’s never completed, because he never gets past this point. I spent three weeks removing notes from the main Batman theme until I got it down to just two notes. I am very proud of it. It’s always the beginning of a theme. It promises that he can become a hero or a complete man, but none of that ever happens, because he can’t get past that moment.
