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'm not really very ambitious.

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.

Madonna is the most famous woman on the planet and has been for a number of decades.

I find it incredibly romantic that people should fight for a cause they believe in and be prepared to die for it.

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