I always have bananas with me for energy.
I have to be careful what I eat before going onstage, to avoid an upset stomach.
My father Philip was an actor and appeared in everything from 'The Onedin Line' to 'Hedda Gabler' with Dame Diana Rigg.
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.
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.
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.
The big thing that Moneypenny changed was the amount of charity work that I was able to be involved with.
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?
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.
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.
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.
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.
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.
