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.
