I remember running into Aaron's Sorkin office and going "The show's West Wing going to work! I know it's going to work!" And it was literally that moment: the energy, the place, the feel. I didn't know the show would be successful but I thought it was going to be good and I don't have that feeling very often. And we were rehearsing all of that not knowing who the President of the United States was!

Just besides how smart Aaron Sorkin stuff is, really, is how visceral it is, how sensual it is. Not sexual, sensual. Always tactile. When you read his scripts, the scripts read fast and the words almost jump off the page.

Aaron Sorkin whole thing was that he didn't want the pomposity of the presidency in the West Wing. But once we cast Martin Sheen and we realised Martin's incredible accessibility, nothing felt pompous or aloof. If the show is about all the planets, let's end it with the sun.

There's always been an ongoing struggle between commerce and art.
