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

There are responsibilities which are parental responsibilities and those are the types of things we prepare the next generation for, but no one tells you how to answer the kids' questions in the backseat of the car when they want to know what the world is for or where they came from or why any of this is happening.

I'm just glad to get any role... the fact that they're all 90 is neither here nor there! Actually, it was Hook that started it. I think it was Peggy Ashcroft who couldn't do the part and somebody was asked how old was I and would I be able to do the part, and the person replied "92" very quickly. And so I've been stuck ever since! But I'm actually very grateful.

Little girls, I am in the business of putting old heads on young shoulders, and all my pupils are the crème de la crème. Give me a girl at an impressionable age and she is mine for life.

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.

There were male colleges, and there were very few female colleges.

I find it very difficult to do anything on my own now because people recognize me. This has never happened to me before because I haven't really done television before. But I suppose if you're in people's rooms all the time, I don't know - I was thinking the other night with people like DiCaprio and, you know, those big stars and Cate Blanchett, and you just think how did they exist? It's so difficult. And I think now it's very intrusive because of these cellphones, you know, with cameras.
