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 think he [Leonardo DiCaprio] is a terrific actor. And I've - I've been rooting and voting for him since "Gilbert Grape." I thought he was so amazing in that one. He was a young man, really very young boy.

I'd done "Gosford Park," a film that Julian Fellowes had written that Robert Altman directed.

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.

The drama school was in Oxford - and it's funny to think of it, but in those days when I started out the University was nearly all male. And they certainly weren't mixed.

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

I'm so moved to hear Celia Johnson again, so lovely.
