I have to be careful what I eat before going onstage, to avoid an upset stomach.

It's one of the oldest theatrical adages: never work with children or animals.

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

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

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