There is no such thing as too much swearing. Swearing is just a piece of linguistic mechanics. The words in-between are the clever ones.

I haven't played Doctor Who since I was 9 on the playground.

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.

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.

I think the most extraordinary thing about fans is the level of excellence that they show in the work that they do. I mean, if you go onto the internet and see some of the fan videos that have been put together, they're just extraordinary; they could be programmes in their own right.

A girl once came to my beery flat in Kensal Green, opened the blinds and cooked me breakfast. I married her.

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.
