There's a ruthlessness to the city now that wasn't there before. I was in Dublin a few months ago, when we were shooting Breakfast on Pluto, and if I saw one kid throwing up on the street, I must have seen a hundred of them.

Acting with creatures that aren't there is kind like acting with an actor who refuses to come out of his trailer. You still have to go on and do the scene.

Acting is invigorating. But I don't analyse it too much. It's like a dog smelling where it's going to do its toilet in the morning.

You just get this profound feeling of instability . . . the Earth isn't stable anymore and then it passes and it becomes more infrequent, but I still get it sometimes.

I always wanted to be a cowboy, and Jedi Knights are basically cowboys in space, right?

It's interesting, the more successful you become the more people want to give you stuff for nothing.

I never thought about becoming a professional singer, but I am in touch with Bono about releasing a musical movie. It will be about an Irish band during the '70s who are looking for fortune in Las Vegas. I should play the singer of the band but I don't want to sing in front of anybody.
