I wanted to know as the director how the actors wanted to tell this story I wanted to know what they thought.

When I became a father acting sort of took the place of what I did in my free time and my children became the main focus. I play a lot and my children play. Both my sons - my daughter's still too young really - have surpassed me with their music skills, which is wildly irritating.

In the old days when I first was coming up, you would turn up on set in the morning with your coffee, script, and hangover and you would figure out what you were going to do with the day and how you were going to play the scenes. You would rehearse and then invite the crew in to watch the actors go through the scenes. The actors would go away to makeup and costume and the director and the DP would work out how they were going to cover what the actors had just done.

I have no interest in movies that take you somewhere dark and leave you there, for no reason.

You'll still work with some directors where that doesn't happen, and sometimes it's out of necessity because you're in a really complicated, choreographed fight scene and the whole thing is being prevised in a computer, so it's been decided months before, but I think that's sneaking into the way action scenes are shot.

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."
