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 like the ephemeral thing about theatre, every performance is like a ghost - it's there and then it's gone.

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 am just surprised to be doing anything at my age actually. When you think of where I am now and where I've come from, I am very pleased and very grateful to be standing up and delivering Julian's great lines.

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.

It made it feel impossible, quite honestly, because filming - you film come rain, come shine, come whatever. And it did rain a lot. And of course, that's what she must have gone through. Of course it rained; of course it was cold... But, you know, it really was quite hard to be out there in the rain.

Don't be defeatist, dear, it's very middle class.
