So there's a choice that I made to tell stories that are still psychological melodramas about domestic issues. The challenge is to figure out how to make 10 films a career as a filmmaker, and that's a really challenging thing.

I'm a version of the same person.

To come to change, there had to be conflict and pain.

I can be incredibly angry with someone, I can be incredibly critical, but... I went through a period where I was reading a lot of memoirs of guards in holocausts and serial killers. I like to understand why people do bad things.

I've worked with non-professional actors, I've worked with movie stars, I've worked with kids, I've worked with older people, and I've found my job as a director is to cast them well and to understand what they need on set to bring the material to life.

I have a career now, and I have to say, five years ago I didn't. I'm 50, and you never know what works, but I think part of that is because - in this way that can't be defined but which can be examined - we cannot work alone.

There was an age in which it was clear to me that my parents weren't perfect, but then there was an age at which I had empathy for that. And that was through therapy, probably. You have to rebuild and you also have to grow in your understanding of whatever it is your parents are facing, and that takes a major, profound shift of perspective from being a child.
