Peter Capaldi IS The Doctor. He really understands the show and who the character is. Everything he says here is absolutely true and obvious when one actually pays attention to the show. And anyone who doesn't like Peter as The Doctor because "he's too angry", or "he's too dark", hasn't been paying attention.
With Fires of Pompeii they offered me the part and I didn’t even read the script and said that I just want to do this. But my wife said “No, you mustn’t. You are a professional actor. You have to read the script and see what it’s like.” David was great. He showed me the TARDIS which I found quite moving. I didn’t realise that a few years later I would be “driving” it myself. It is a very wonderful place to be.
