I had invited 50 or 60 peers and friends, most of whom were parents, to see the film [Trust], and I asked about the last scene. It was interesting because it was split right down the middle, 50/50. About half the audience wanted it to end with the very emotional scene between Clive and Liana, and that feeling of realization and catharsis. And, the other half were adamant about keeping that last scene.

I think a huge amount of it is because of the Internet. Every single thing in the world is accessible with a few clicks. Almost every child, by the age of 13, has seen pornography. That's clearly different. It used to be really hard or really humiliating, as a 13-year-old, to access pornography. If you wanted to take a look at a Playboy, it was really challenging. Today, it's a joke.

I love helping someone else tell their story, but I like being the storyteller sometimes.

When you see Liana [Liberato], who at the time was 14, there is an inexperience and innocence that you can't act and you can't fake.

I think I'm a very very nice director. Very supportive, very nurturing. I definitely try to challenge my actors but I think I'm very supportive.

And the thing is, every time you start a new show or do a new series, you're committing to another six years.

If there's something I want, I go for it. I just think about how I'm going to go for it.
