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 TV.

I always have bananas with me for energy.

I tend to opt for relaxed family holidays when I can.

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.

Something like 'Sex And The City' was insulting - women all clawing on to their youth when there's such ripe territory in honestly exploring women's lives as they get older.

I've been married to the same man - even after the separation - longer than most people in this business. I'm sick to death of people mentioning it.

I managed to slip two children out in the middle of my career and have been lucky with all the work.
