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 was brought up Catholic. I'm lapsed. From the age of three I was with the nuns. Now I'm an atheist.

For some ungodly reason, I end up being naked in a lot of stuff. But there is a certain grace and kudos that come with taking your clothes off on the first day, a respect that is given by the rest of the cast.

I simply don't understand the refugee crisis. The history of humanity can be told through a story of migration and settlement. If I can't protect my family, I'm coming to where you are; I'm just coming. It's a round world, and we've all got to get on with it and move on.

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.

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.

I'm sure some people have an absolute grasp of where they are in their careers. I just don't think about it that much.
