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.

My blood runs cold when I hear the 'great news' that we have found a marker for the Down's syndrome gene, which means we can identify it more easily. Why is that good news? It's only good news if you're going to terminate.

My first film crush was Mark Lester as Oliver Twist in the Carol Reed film.

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.

TV feels quite constipated, and the thing I find particularly difficult is the branding of the channels where it's not 'Is it a good script?' but 'Is it a BBC2 script?'

I'm feeling incredibly Botox-tempted as my face collapses around my shoulders.

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