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

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.

To me, it's a very moral film. If my son were a teenager now, I would drag him to see it.

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

She loses 50 pounds in the film, and goes from fairly sane to totally out of her mind. So for the first part of the film I was wearing a 40 pound fat suit, which is very, very uncomfortable. But the worst part was the neck.

I sketched out a rough story for them and the director said, well it's a good story but we have the go-ahead from Universal to make this script and did I want to do it. I said no, and they left.
