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

One of my earliest memories is of being about three and a half, climbing through the legs of a man who I didn't know was the famous actor, Patrick Magee.

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.

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.

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

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.

Filming is quite exciting because every day is different, but it can involve long hours standing around in chilly locations. Theatre is a very different challenge because every night you're striving to keep it fresh, even though you might have been performing the same play for months.
