I couldn't write a happy movie or romantic comedy to save my life. Yes, Noel Coward's an idol, but his plays are serious to me. 'Private Lives' and 'Design for Living' both have an edge. Without psychoanalyzing myself, I think I exorcise my demons in my work.

There are clearly many good politicians who are guided by religious belief, so the mix can work. But there's a line to be drawn. It would be hugely dangerous for a country's laws to be set by the scriptures, and particularly those of the expansionist religions.
