Myself and Yorgos Lanthimos, we spoke a little bit and I was at a certain body weight that I was closer to making a statement or defining the character physically by losing weight. There was no justification for him to be emaciated, but I thought, say I was 165, I thought what if I went down to 155 and have him rail-thin? And Yorgos was like, "Well, if he's very thin I think maybe it will speak to some kind of psychological trouble that we want to stay away from," and I was like, "F - -, you're right."

I must say, I am thrilled with my fan base. For some reason some of them are quite young, so they are quite frightened. I remember when I did 'Click' and I'd see Adam Sandler's fan base. He's the guy that people feel that he's their best friend, so he's walking down the street and people sort of high five him and want to tell him a joke or invite him to come home and have a sandwich with them. Mine are not like that. Mine tend to go: 'Argh,' and look horrified. They shake and take a picture from a really long way away. I do feel I've got quite good, respectful ones though.

I love the grandiosity, how sweepingly entertaining films can be. And I think there's a place for films that pry more into the human condition.

Most of actor's work is done at home, in your hotel room, in the wee hours of the morning thinking and reading and feeling, walking around and listening to music. It really just because an internal exercise, whatever skills. It's great if you have to learn something new for a gig and designing a character physically is always fun but it does become an internal exercise in separating the wheat from the chaff.

The original WAS a fun film. [Paul] Verhoeven made a couple of 'Robocops' that were so great, too. I think the level of excitement is great and Arnie [Schwarzenegger] was particularly charismatic with that chopped up English, and the size of the man with his confidence and sense of humor.

Sometimes I have experienced at the start of a film you're very excited and enthusiastic and you've done all your preparation internally and externally and you start the film and it's all go... Then your attention goes somewhere else. Your energy goes into telling the story, so you don't have the same amount of energy to be objective, and that's okay because sometimes you become a subject of the story and you're inside it so much that you don't need to keep on looking on the outside.

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.
