I met Tom Baker doing a voice-over when David [Arabella's friend, David Tennant] wasn't at all well known. We were doing this voice-over together and I said to Tom, 'Oh, my friend's a really, really big Doctor Who fan,' and he replied, 'Wait!' He got his cheque book out and asked, 'What his name?' I said 'David Tennant'. He wrote, 'To David Tennant, seventeen pounds forty five', signed it and I asked him what it meant. He said, 'He'll know'

My parents' generation's benchmark was simple: Fat Equals Bad.

Sticking to a diet required me to have a permanently low self-esteem. But happily, I developed other skills beyond a fluctuating weight, eventually building up a different source of self-worth.

There is an inherent tolerance and kindness in the state school teenagers I know.

If no one saw - it didn't count. It's only when you eat in front of strangers or people that make you feel guilty that food is really fattening.

I don't think I've got the expertise with which to nit-pick, and I freely admit that my motivation to support charities has been emotional, rather than as a result of being particularly well informed as to how the money is used.

I spent my entire childhood living abroad because of my father's occupation, so we were on long-haul flights all the time.
