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.
