I wanted to work on this central problem of killing. How you go about killing. Now, in the film I had to kill my children - well, I didn't want to get that far.

I always wanted to play Joan of Arc. I've always wanted to do that. Now I'm thinking, 'Maybe there's a story in Joan of Arc's mother!' If I don't hurry up, her grandmother!

Their life is about getting enough money to put food on the table to feed their children, and that's it.

I talked to women who lived there, to get their speech patterns and outlook on life - and how narrow that is.
