It's tough and it should be tough - it should never be easy to be given millions of pounds to make a drama. The coalition government is doing terrible things to the BBC, but drama will survive even if we end up putting on a play in a backroom of a pub.

Maybe that's when bad scripts are written, when you choose the theme first. I consider that I've something to say when I've thought of a person, a moment, a single beat of the heart, that I think is true and interesting, and therefore should be seen.

Anything works, as long as you write it properly.
