The big thing that Moneypenny changed was the amount of charity work that I was able to be involved with.
I adore acting; it's in my blood - quite literally - but I can honestly say the most creative thing in the world for me is being a mother.
When I got on stage, I would have a rush of adrenaline; everybody gets it. Normally after the first night it becomes more controllable, and as long as I could ride the wave, I was still in charge.
The bravest thing I've ever done is fly to New York. I'm simply terrified of aeroplanes - I am the woman you see weeping at the airport.
Agatha Christie holds special personal memories for me because my mum, a television producer called Pat Sandys, had been the first person to persaude the Agatha Christie estate to put one of her stories on T.V.
I'm very shocked when I look at television and I see such an aggressive youth and image obsession in the representation of women on our screens.
It's always been a dream of mine to be Ginger Rogers or Cyd Charisse, and here I am performing alongside Robert Lindsay and being directed by a major Broadway producer. Who said dreams don't come true?
I'm an appalling flyer. I get very tense, although I no longer weep uncontrollably for no reason - I just sob if there's turbulence.
Not a lot of people know this, but I'm very good at mathematics. When I was an angry teenager, I used to sit in my room and do quadratic equations to calm myself down.
If I pop off and do something drastic, everyone's going to realise because they know I'm 50. Anyway, middle-aged women are sensational.
My father Philip was an actor and appeared in everything from 'The Onedin Line' to 'Hedda Gabler' with Dame Diana Rigg.
I have to be careful what I eat before going onstage, to avoid an upset stomach.
