There are lots of people I admire and respect, but I don't necessarily want to be like them. I'm too happy being myself.

I respect journalism. I was always very aware of journalism from a very broad point of view, but I'd say my baptism by fire was doing the Donald Margulies play Time Stands Still. That for me was a real education because I spent a lot of time with some incredible journalists, war reporters particularly - Bob Woodruff, Dexter Filkins - people who were very helpful in painting the picture for me and reading the accounts of people and what they experienced, a lot of PTSD.

I know that Madonna is not a first-time filmmaker, but I have worked with a lot of first time filmmakers and I have worked with a lot of inexperienced film directors so that never has particularly worried me - I find it quite exciting - but I have never worked with a director who has had so little experience of directing who was so prepared.

I don't have any expectations as an actor and being rich and famous is not my driving force.

The reason I wanted to be an actor is that I don't want to play me for the rest of my life and make money out of that.

I, like many people, had some sort of preconception about Madonna. One of the preconceptions was that she had the extraordinary work ethic, which turned out to be absolutely true.

I'm attracted to seeing how different I can be, pushing the boat out.
