You don't always want to be using the music in a way to express ideas inherent that are on the screen. You might want to work more around the fringes of the story, and work more with the subtext, and add more depth to the story through the use of music.

There are many things that have stayed consistent. But the biggest change, of course, is technology, the way it's used, the way films are shot, the format that they're shot in, and the way films, of course, are edited. It's very different than it was in the past.

Saturday Night Live was actually started with a show that Lorne Michaels and I did at a summer camp called Timberlane in Ontario when we were 14 and 15. We would do an improvisational show with music, comedy and acting.

Music is essentially an emotional language, so you want to feel something from the relationships and build music based on those feelings.

I live in Tuxedo Park, N.Y. and spend time in the West Village, where my wife Elizabeth Cotnoir, a writer-producer and documentary filmmaker, has an office.

The techniques of different directors are very different, and people have different ways of expressing ideas in film. I'm happiest when working with a director as I would be if I were an actor. I'm wanting to provide a really good performance.

Theater and film are essentially the same - just different kinds of storytelling.
