The difficulty of looking at a system like natural selection if you have any sort of moral sense yourself, is almost what makes it beautiful.

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 do feel that scripts get developed now to a point where they're sort of actor-proof. If the actor is not very good, the narrative still survives because it's all in the dialogue. Not to say there aren't great performances in English-language films, because there are every year, but the 1970s were awash with great performances, and I was wondering whether it had to do with the amount of space and the amount of responsibility given to the actors.

I remember coming on my first set and it being a playground of things I wanted to ask questions about: cameras and lenses and what the lenses do, what's the focus puller doing and how does that work? Why is there less margin for error when there's less light? I was always asking questions and watching directors closely.

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.

An actor has so much less space and responsibility. Sometimes you come on, and there are already tape marks for where you are supposed to stand, and the dialogue is already decided on. If you want to make a change and contribute something, it has to be approved by a number of people.

My experience of people is that they are infinitely forgivable.
