You have a certain objectivity, as a member of the audience, and you can come away maybe being provoked into a certain discourse or a certain arena of questioning, regarding how you would deal with things that your character has to deal with. Whereas when you're doing a film, once you start asking, "What would I do?," you're getting the distance greater between yourself and the character, or you're bringing the character to you, which I think is self-serving, in the wrong way. The idea is to bring yourself to the character.

I just recently realized. It's very strange. But doing fight scenes with Kate [Beckinsale], I was little bit more cautious. You can go harder with a guy, which I don't mean as an insult.

You consciously look after yourself, whatever that may be to you, whether it's going out for a few drinks and a bit of dinner, or just hitting the couch and watching TV, or going to the gym or yoga class. Just being aware that there's a potential for you to be in it and respecting wherever you find yourself is good enough.

[Yorgos Lanthimos] is really a master I feel, I really do.

I don't go to the gym or practice yoga. And the closest thing I have to a nutritionist is the Carlsberg Beer Company. I just have the appetite of a pigeon.

I certainly do believe in monogamy. I don't believe that it's for everyone. I don't believe that marriage is for everyone. So much of life is begging to be chosen how it wants to be lived. Much more than most of us realize.

Pain seems to be easier, or melancholy seems to be easier to portray in a character. I don't know if that's because I'm a human being or because I'm an Irishman or both.
