"Chris [ Nolan] and I have a strange way of working from the non-movie process, where after all these conversations and reading the script and more conversations, Chris went out and shot the films and the first thing he did, he wouldn't show it to me until I had written the music - not out of meanness, or anything, it just sort of seemed an interesting idea to see if there was some synchronicity and letting me use my imagination to the fullest instead of being constricted by cuts and images."
