I think once you're a mother to one, you're a mother to them all.

When you've been raised in care, rap music isn't just about guns and sexism. They're talking about real things you can hang on to, problems of identity that you have sympathy with. It's not just about the music, with rap: when I was in care, it meant a whole lot more than that.

I like to stretch my acting muscles.

I wanted to make a film - and I've been wanting to do this for 16 years - about life in care, and bring it to the public's attention, because I had never seen anything, on TV or in the cinema, which said: 'This is how it feels to be a kid in care'.

It's fantastic to strive towards a nice life where you eat nice organic food and your children go to a nice school and you can afford nice clothes and nice perfume and the hypoallergenic make-up. But there's never a day goes by, and I mean this from the bottom of my heart, that I don't think about where I'm from.

To be honest with you, a lot of directors can be very lazy.

I think there's a very fine line between the type of performing that some actors do, and being in a state in your mind where you actually believe what's going on. If we weren't actors, what would we do with that ability? Would we not be slightly insane? Mentally ill? I don't know.
