Having started out in theatre, I feel an impulse to do it as much as I can

I think any actor that says 'I never watch my films' is a liar because you have to watch it at least once and also you're going to watch it when you're doing your ADR.

I was obsessed with Batman as a kid. I did the film in part just to be near the Batmobile. But I also think [director] Christopher Nolan made a very fine, intelligent film.

I hope that I have gained some wisdom, but I don't know. I have kids, and that certainly puts things into perspective. I think I'm a more patient person. I hope I'm a more patient person. I'm a little more relaxed about the peripheral side of this business, which I used to find very confusing and alarming.

I think if you play characters, it's very important not to ever tag them with any sort of disorder, or diagnose them, or whatever. You have to normalize the behavior to get inside the character.

And, for any performer, to be able to go deep into character is fantastic. In film you only get to do that if you're the leading character. But in television you get 18 hours to really test the audience and take them to the edge of how far they will go with this character. I can step over this line and I love that.

Every Irish person of my generation and earlier, we were raised Catholic and we'd have to learn it in school, we'd to learn the catechism by rote.
