I guess secrets are part of the fabric of everybody's lives. I mean everybody's lives, and guilt is part of the fabric of everybody's lives.

I did my homework and didn't go out much, and had a very highly developed kitsch fantasy life where I dreamed of being a dancing girl.

I'm an optimist by nature, myself, I think.

I spent a lot of time with a real detective, a lady detective inspector who was the only female detective inspector in the whole of East London. She and I hung out a lot. She showed me what she did and I spent time with her. So, [she was] a lot of the inspiration for the way I dressed and sometimes the dialogue in those interview scenes where we're cross examining and questioning the youths and trying to get a confession out of them.

When I'm panicked about my love handles, I go to the YMCA and get obsessed with Kid Rock videos as I'm on the running machine.

I'm always sort of anticipating life being difficult, but on a basic level, that's sort of on the surface, on a basic level, I'm optimistic in the sense that I think it's all going to be alright in the end.

It is brilliant going to the theatre and being forced to sit and listen and think about life. It can be almost a near-religious experience.
