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, 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.

All directors on all sets behave slightly differently depending on what the scene is. For example, if you are doing a love scene, which is intimate then the director is likely to be intimate. If you are doing a scene where everyone is mucking around and laughing then the director is likely to start with that. If you are playing a scene which us incredibly heavy and everyone getting killed then there are probably not many laughs on the set.

It felt good doing a physical job, and going home each evening feeling like I had really done a day's work.

I went further and further back through the centuries to get a sense of perspective but now at least I understand why Irish history evokes such strong passions and emotions.

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.
