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 tell people that I'm a Christian, but I don't think it's giving an insight into who I am or what I'm about.

The only way I'll ever run a marathon is if I'm involved in the administration.

The siblings of special needs children are quite special. Absolutely accepting and totally loving, from birth, someone who is different mentally, and has a different way of seeing the world, is a wonderful trait. It's a trait I wish there was another way of getting, but there isn't. And it does involve a degree of not having it fantastically easy.

All I want to do really is get married and be a matriarch.

I don't leave London, really, and I don't do theatre, because I want to put the kids to bed.

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?'
