I do have the ability to explore life and to be over the moon at the smallest thing - a few pints and a craic in the pub and I'm in heaven. But I have a melancholy side to me as well. Acting allows me to feel things, it kind of buys me human experience. And I don't mean this as acting as higher cause, because it's not, but it does kind of have a higher awareness emotionally.

I'm not going to experience the reality of hardship that sometimes my characters live in. I'm very cautious about that.

Yorgos Lanthimos said, "What about if he's a bit soft?" And I said, "Yeah, I think you're right." He just comfort-eats a little bit too much. He's just asleep in his own life and has let himself go. And the mustache, I don't know if it was him or I suggested it. But I remember my sister was watching me eat and she was like, "God, does he have to be fat?" And in retrospect I couldn't think of David being any other way because it affected the way I moved. It really did. It slowed me down in a way that I felt was conducive to kind of tapping into the spirit of the character.

I'm not keen on cars and motorbikes. I tried to be a biker, but it wasn't me - I bought a Harley-Davidson and dumped it.

Desperation will allow you to do incredible things in the name of survival.

I'll try anything. I'll do anything. I'll explore. Try different takes.

I'm just a true Irish boy at heart.
