I am trying to be as impartial as possible. As you can tell from the trailers for Mad Men, I am a person who believes that you should know nothing.

The chance to tell personal, language-specific, culturally specific stories is really flourishing on TV and I think it's just the nature of movies and international demands that you need to get a much bigger audience. TV is more like independent film was. The forms of adult drama and certain kinds of sophisticated comedy, there's no room for them in the tentpole movie universe.

On the set, I visit the set for a lot of the rehearsals, and there's always a writer on set. And then I'm involved in post-production, very intensely involved in editing, and the sound mix and color timing. Really, I have about nine jobs.

I do find it sometimes that people project their own feelings on to the characters and I think that there is a certain amount of sexism - I mean the proprietary nature, for men and women.

I think there's a kind of elegance to it, to work within that framework where what you don't see is often more enticing.

You can do a lot with a commercial break - you can change days, you can suggest the passage of time. So sometimes that's a great thing artistically, to know that's going to be there. Obviously you'd always prefer that people see it straight through, and you don't want them to be taken out of it by advertising, but that's the reality of what's paying the bills here.
