Screenwriting is still a challenge for me. It's more technical than creative. You have to be a very good journeyman plumber and put the proper parts together. Then, if you can still inject a little bit of something worthwhile, you have done as much as can be expected.

The filmmaking process is a team effort. A screenwriter cannot possibly do exactly what he wants as if he was writing a novel.

Rock n' roll was my art school. For many people from working-class backgrounds, rock wasn't a chosen thing, it was the only thing: the only avenue of creativity available for them.

So, through all that early professional career I would occasionally do a musical, a pantomime or a play with songs. The next stop would be a Shakespeare, or an Ibsen, or a play by a brand new writer who had never done anything in the theater before.

Sometimes you write music to a script or while a film is being edited. Sometimes I write without seeing any images, but that's rare. The approach is often based on practical decisions, but I'm interested in the narrative and physical space that music can occupy in a film or play.

When I make film music, I'm a filmmaker first and foremost. It's about serving the needs of the film. You're telling a story; in a way, you stop becoming a composer and become a storyteller instead. You tell the story with the most appropriate themes. How you approach these things is a very personal matter, but your goal is to tell the story first.
