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

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 am more comfortable doing a drama.

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've started films like Miami Vice where I'm in really good shape and I look back on that film and see the moustache is bigger as I've got a larger face.

If you need to get in physical shape for a film and you have to maintain that for six months, at the start of the film, I was never able to do it.

From my experience, the only thing you can do is take what's written on the page and try, through your own curiosity and investigation, to make it your own and honor what the original intent was.
