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.

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.

My best friend is my husband.

I think one of the most important things I can give my children is the right to be themselves.

I've always had this sneaking suspicion that I get a kick out of the insecurity.

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.

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.
