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

I've lived most of my life in Manhattan, but as close as Brooklyn is to Manhattan, there are people who live there who have been to Manhattan maybe once or twice.

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.

What a lovely surprise to finally discover how unlonely being alone can be.

Nobody would want to leave that film to go get high.

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