I'm pretty good for an old geek.

There is no greater symbol of the artistic spirit of Scotland than the Mackintosh building. But more than that it is a symbol of where art belongs, rising as it does out of the heart of a great city. A mighty castle on a hill, it is a part of me, and of all Glaswegians.

I'd say, don't listen to what anyone says: you're good. Go put your anorak on. Get your thick bottle-top specs. Draw your little cartoons and your comics and keep writing to the BBC.

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 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.

I suppose I just like being arty. That's all. Arty.

'Doctor Who' belongs to all of us. Everybody makes 'Doctor Who.'
