Logic doesn't really provide for loyalty. If your logic changes suddenly and things not make sense, you can alter your allegiance, but love stops you from being able to do that.

I really like telling stories. When I was a kid, I wanted to write songs. In quite a fundamental, gratifying, childish way, I enjoy the doing of telling a story.

In a world of increasing grey areas, we are becoming more and more entrenched in black and white positions.

Actors can be many things - vain, venal, self-serving, obnoxious, bullies - but all of the good ones are great storytellers. I wanted to watch what my actors were doing and how they were telling the story.

An agent friend of mine who will remain nameless said you can't make a romance about homeless people; nobody wants to see them kiss. And I thought, what a repulsive, repugnant, extraordinary thing to say. I had to think about the fact that the world is probably full of other people who feel like that. The very idea that we spend time trying to humanize humans is extraordinary to me.

I was always waiting for the secret to be handed down to me. Ron Howard asked me what I was waiting for and I went, "Ron, I'm waiting to know the secret. I keep feeling there's some sort of secret that's going to passed on from a director." He went, "Oh no. There is none. You've just got to on and do it and make mistakes and figure it out."

The only thing I think I can be accused of about paparazzi is being really naive. I didnt think about it coming along with the job and I never, during my three years at drama school, fantasized about one bit of it.
