One year you go in for auditions, and everybody thinks you're the queen of comedy, and the next year, you're so 'yesterday,' and it's not because you've done anything, or your ability has changed; you haven't been in work because you've been putting on weight and then trying to lose it.

When I'm a brunette, it's four times harder to hail a taxi. Then I go blonde again, and suddenly there are taxis everywhere.

I truly would love to be a designer-label girl, but I am very much High Street.

As a writer myself, my job has very often been to also write on the job. So you get the script and a vague idea of how the scene might work, and you then add funny words or change the script. I'm not the world's best writer or the world's best actor, but I can do that thing where I can fix - or ruin - fix-slash-ruin, add quirk, add value.

I start the day with the intention of doing 4,000 sit-ups but then have to work.

Red carpets and dressing up are a part of work that I enjoy less than some people.

My mum's from Yorkshire and my parents aren't snotty or posh - they're very hard workers, both of them.
