(On distinguishing character from actor)
David: I remember, after seeing Jon Pertwee turn into Tom Baker in Doctor Who, having a conversation with my parents at a very young age about actors and what they did. I remember getting the distinction between a character and an actor, as they explained it. I understood what fiction was very clearly – and I always feel uneasy when people talk about children not understanding the difference between fantasy and reality. I can only have been three, and was just enthralled by Doctor Who. But I was quite clear that I didn't want to be a Time Lord – I wanted to be the person who played a Time Lord.
