I think Georges Feydeau said comedy is just tragedy speeded up.

I'm just happy to be a film where for once I don't have to worry about my hair, because my managers are always complaining about my hair looking depressing in my movies. Which is true. I mean, it's true.

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.

I had friends at school, but I was never part of a gang and I dreamed of that sense of belonging to a group. You know, where people would call me 'Em' and shout across the bar, 'Em, what are you drinking?' after the show.

I must have been a really pretentious little girl.

In my first few years as an actor, I took one terrible TV job after another. But even as I laughed off my awful roles and made fun of myself to friends, my work made me cringe - I dreaded anyone's seeing it. I was crushed that I wasn't doing anything I was proud of.

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.
