"I find music the the clearest and easiest way in to what a movie will feel like - more so than visual references or other movies or dense dossiers of research material. Every now and then I'll send a piece of music or two to people I'm working with - actors or heads of department - when I think it'll help them get a sense of the kind of movie I'm proposing. Often those pieces will end up in the movie - sometimes they won't."
