There are days when I think: what if I just checked out? What if I grew a beard and went off to live somewhere remote? I have often wondered about the freedom that would bring.

I think the other honest attraction was that I just grew up loving watching TV and loving watching film, and there's so many directors and actors that I dreamed of working with, I just really wanted to take a crack at it and see if I could ever work with some of those.

And the thing is, every time you start a new show or do a new series, you're committing to another six years.

I never say never, but I'm really enjoying the freedom I'm having right now.

With the success of the last three or so years, when a lot of people start treating you differently, there's a danger that you may start to think of yourself differently. You rely on your friends to say, 'Hey, wake up!

If someone doesn't believe enough in your product to put money in to it, then you should rethink how good the product is.

I think a huge amount of it is because of the Internet. Every single thing in the world is accessible with a few clicks. Almost every child, by the age of 13, has seen pornography. That's clearly different. It used to be really hard or really humiliating, as a 13-year-old, to access pornography. If you wanted to take a look at a Playboy, it was really challenging. Today, it's a joke.
