I had no idea that that was around in the family anywhere. Maybe it never was. But - so they broke the way for me, if you know what I mean. I have no idea where I got the idea from to do what I do.

The performances you have in your head are always much better than the performances on stage.

Alan Rickman was such a terrific actor, and that was such a terrific character that he played. And it was a joy to be with him. We used to laugh together because we ran out of reaction shots. They were always - when everything had been done and the children were finished, they would turn the camera around and we'd have to do various reaction shots of amazement or sadness and things. We used to say we'd got to about number 200-and-something and we'd run out of knowing what to do when the camera came around on us. But he was a joy.

I just did adore Daniel - Daniel Radcliffe, who I had worked with before "Harry Potter" and spent a long time telling all the producers they had to see him because I thought he was so terrific. And it's been sad thinking about it because of Alan Rickman.
