I love this story, and the end-result of Nolan's little subterfuge is really quite extraordinary:
Before (re)writing a word of Interstellar, Nolan did something he had never done before, something that speaks to his desire for more emotionally potent work. He asked composer Hans Zimmer to write some music for the film, but without telling him about the genre, title, characters, or plot: “I said, ‘I am going to give you an envelope with a letter in it. One page. It’s going to tell you the fable at the center of the story. You work for one day, then play me what you have written.’
