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.

I definitely used to write a lot at school. Comic poetry and drawings about people.

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 dont have the self-discipline for diets; I break rules I set for myself, so I try and eat more healthily, juice more, and avoid sugar.

Getting a new passport took me a stupid amount of time. I had to go back five times with different photographs because they kept saying I was smiling, which is against the rules. I was not smiling.

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?'
