"We had finished the whole movie and we had scored it, and I got on the phone with everybody at the studio and all of the producers and said, 'I need you to give me one more crack at No Man's Land please.' And I literally got them to bring all the musicians back into the studio – which is a very expensive and laborious thing to do – and I had our great composer, Rupert Gregson-Williams, write an entirely new piece for it based on a sort of hunch that I had that there was one step further [we could go]. And he actually ended up composing a whole new piece of music that we scored after we had locked everything, which is the score that went in right at the last minute. Everything in my gut told me that song was the right song, but then it was over, it was done, it was out of my hands and the movie was complete – so I really never got a chance to see [the No Man's Land scene] and know it with an audience until very close to the premiere, when finally it was like, 'Oh, that's it. That is the scene. That's as far as we got it. We can't do better. We tried everything that we could to do better and there it is.' And it was pretty incredible, honestly, the night of the premiere when people reacted the way that we did."
