People were dealing with CGI for the first time, so I think we were really unsure as to whether it would be a huge success or a big flop. ... I thought the scripts were so good. It had a kind of domestic element which I'm not sure it ever had before. I think we were feeling quite confident about that. ... In terms of whether it had a place in the world when it aired, I think everyone was quite unsure. I didn't know until it aired and people really seemed to like it.
