Peter Capaldi has become to the new series what Tom Baker was to the older one. The "definite article" you might say. I have been watching Doctor Who since the Tom Baker era and will miss Peter's portrayal of the Doctor as much as I fondly look back on Tom’s.
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.
