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

I've played my fair share of unpleasant character, and I have to tell you that you sleep better when you're playing fun characters. You think you don't take it home with you, at the end of the filming day, but subconsciously, there's something floating around in the background there.

When I left school I went to Australia for a year and worked in the drama department of a school in Perth.

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

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.
