What got you started?
I just had a desire to entertain from a very early age. When I was really teeny, I used to pull the curtains across the bay window and come out, play my plastic ukulele, and pretend to be Elvis Presley or Lonnie Donegan.
Who or what have you sacrificed for your art?
My health. I didn't realise how stressful acting is until I did [the BBC film] A Short Stay in Switzerland. There was a collage of my character having all these health tests. A real nurse was doing them, and she said: "Ooh, your blood pressure's really high." It was because she had taken it during filming.
Has fame been difficult to cope with?
It would be churlish to say it has, but it has its problems. It's odd for kids.
