If you put people up on pedestals, there's only one way for them to go, and that is down.

I think that as you get older, you become aware of everything that could go wrong.

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.

I lost a girlfriend when I was in my 30s. She was 46. It all sounds so trite, but I put a Post-it on my dressing-room wall. It said, 'The past is history. The future is a mystery. This moment is a gift, which is why it's called the present.'

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.

Nobody can prepare you for the loss of a parent.
