I think that people like the idea that fans are sort of slightly eccentric and strange, but generally I've just found them very creative and warm and cheerful.

I'm a huge fan of The Sopranos, and suddenly, you find yourself going one-to-one with this guy who you've been watching for years, watching every flicker in his eye and every detail on his face.

I'm so lucky to have worked with Burt Lancaster, who I remember was one of the first people I'd heard swearing in a really interesting way.

It'll be sad not to be Doctor Who anymore because that's an incredible thing to wake up in the morning and go, 'Oh, I'm still Doctor Who!' And you can go and blow up some monsters, and that's how you spend your day. And also when you walk around people don't see Peter anymore, he's not here, it's Doctor Who they see and he gets many more smiles than I do. It'll be sad to say goodbye.

I'm sure if Shakespeare were alive today, he'd be doing classic guitar solos on YouTube.

I think acting, oftentimes it's not about lines, it's about spaces in between lines and expressions on people's faces and their relationships. You can tell your own story, or a story that you're interested in, even if the lines don't necessarily point you in that direction.

Chris Addison is a stand-up comic, but his ability to act is extraordinary, to be so natural, I've taken 25 years just getting to that level.
