I think it's necessary to keep moving forward. I've always said that nostalgia is death, really for anyone creative.

You need to be as clean of a slate as you can be, as an actor. You have to try to be open to every experience.

It seemed to work on camera. And there's very few films - because you make a lot of films and you meet people and you work very intensely and intimately and then you're gone - but there's a few where you actually make friends, and this [The Fall] was one.

You're an actor who's Irish, not an Irish actor. And you shouldn't be limited by your extraction.

At the moment I'm doing this space movie, so I'm obsessed with physics and space travel. I know three months down the line it's gone. Then I'll be able to superficially say stuff about space.

I personally think if something's not a challenge there's no point doing it because you're not gonna learn much.

You know, I'm a skinny Irish guy.
