There is a danger, if you cast someone who is 18, 19 or 20 to play 14 or 15, that very subtly, almost unconsciously, the audience is, "Oh, this isn't so bad."

If someone doesn't believe enough in your product to put money in to it, then you should rethink how good the product is.

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 would say acting on stage is my first love.

I think it was really crucial that the actress was age appropriate. There are films, such as An Education, where that wasn't the case, and I think that really affects how you receive what you're watching.

Can I tell you how strange it is to look in your rearview mirror and see guys in cars tailing you?

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