I think you have to be scared every morning that you go out to shoot, or you lose your edge. With actors, there has to be that adrenaline and you have to keep challenging yourself, and I certainly challenge myself, as a director.

Unlike a lot of British directors, I hadn't done any theater. But, I had a great mentor who said, "What you're looking for is exactly the same thing you've done in your documentaries, which is moments of emotional truth.

Authenticity is what I've always gone after in my work, and I understand what feels emotionally right, instinctively. Working with actors has just come with experience.

Good acting should be invisible. You shouldn't be aware of the acting. It should feel real.

I'll never forget the moment when I saw a red light go on, on the camera, and that image translated to the monitor, and then a different light went on and the shot changed, and I went, "Wow, that's how it's done! That's how that gets to my TV! This is what I want to do with my life!" I literally had that moment of epiphany, at eight years old.

When I was eight years old, I knew I wanted to make films.

I think the biggest thing is just making sure that you do the work that you connect with, personally, and that you do work where you can really bring something to the table. It's just about being truthful to yourself.
