I can be intolerably jealous and I think that’s what’s driven me. My ambition knows no end.

If I wasn't so insecure about myself I wouldn't work as hard as I do. I am constantly seeking approval.

I don't live in Ireland, I live in London with my girlfriend; and it's because of the globalization of our planet, it's not necessary to live in Los Angeles to be a successful and any country is just an airplane ride away. If there's a director who wants to meet me or if there's something I have to do, I can just hop on an airplane - the world's small now.

I didn't use a phone until I was 14.

You go through your 20s sort of like a chrysalis in many ways, stretching into your own skin and trying to bust out of a cocoon.

Even though I've had the body of work I've had, and the success I've had, I do not rest on my laurels whatsoever.

I could sing and play as well. I've got some brothers; one of them is the drummer in the band. They're good musicians. I play for fun. They play properly. Music in general, I grew up in a house of musicians. Everybody's life has a soundtrack, I'm sitting here talking to you but there are horns beeping outside. I know I'm in New York. That's an element in the film as well. How strong that sense can be.
