My first job when I got my equity card was acting in 14 plays back-to-back. Playing that many roles, you look for ways of differentiating the characters physically, which goes hand in hand with understanding them psychologically.

I was thinking about that. I was thinking, this is like our Boyhood; this is like our getting together over 12 years to make - this our Apehood! I mean, this is it! For me, the relationships, all of those things, over such a long period of time now with actors, but also seeing the characters grow, develop, and change, and go through different situations.

I wanted to be a painter, really, when I was growing up as a kid. It was one thing that really took a grip on me.

I love the whole kind of notion of transformation for me is (what) excites me about not only acting, but storytelling. I love, I love that notion of a slightly larger-than-life artistic truth, you know, magnifying real emotional truth (or) finding something about human condition (which), you wouldn't necessarily think you can learn from characters such as Kong or Gollum, but actually they are, you know, these huge amplifications of a human psyche and I suppose those kind of roles have always attracted me definitely.

I understand why people went nuts for 'The Artist.' We use words so much, it's nice to be able to explore a different way of communication, to be able to express silently what someone - or something - is thinking or feeling.

I do listen to myself sometimes and think, 'Is my moral compass so easily swayed by the characters I play, or is it me growing as a human being?'

35mm film isn't ticking away so it's subconscious - performances are allowed to breathe in a much more real way I think.
