Chris and Toby are far too sane to be upset any more.

Sort of what you do in drama school when asked to play something way out of your reach. Anyway, we used to laugh a lot about that. I used to say I'm not going to act old, Penelope. I'll just be myself.

I tend to head for what's amusing because a lot of things aren't happy. But usually you can find a funny side to practically anything.

I'm not my mother. And so I'm not raising my kids in the same way. I don't respond in the same way. We don't spend our days in the same way because I don't necessarily enjoy the same things she likes to do.

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.

People say it gets better but it doesn't. It just gets different, that's all.

I'm far, far, far from that. But of course, that's one of the joys of acting is that you can move up in the world, even if - you know, in the characters that you're playing, even if you don't.
