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.

It was - it's always very nice to be somebody rather grand.

The chemotherapy was very peculiar, something that makes you feel much worse than the cancer itself, a very nasty thing. I used to go to treatment on my own, and nearly everybody else was with somebody. I wouldn't have liked that. Why would you want to make anybody sit in those places?

It's true I don't tolerate fools but then they don't tolerate me, so I am spiky. Maybe that's why I'm quite good at playing spiky elderly ladies.

My career is chequered. Then I think I got pigeon-holed in humour; Shakespeare is not my thing.

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 don't think films about elderly people have been made very much.
