Sometimes when I'm writing I'll play Cole Porter, just because the rhythms and the lyrics are so perfect that it's like having a smart partner in the room. I have a huge collection of music that I listen to when I'm writing, and I also prepare a lot of music before I start directing. I put it all onto an iPod that I have with me on the set. It's helpful to the actors, because for an emotional scene, I'll play it and say, this is how it feels, to keep us in the zone.
