I never studied anything about film technique in school. Eventually, I realized that cinema and theater are not so different: from the gut to the heart to the head of a character is the same journey for both.
In the studio system, things are expected of a film. By the first, second, third act, there's a generic language that comes out of the more commercial system.
And although I've been very fortunate in the film work that's come my way, I need to get back to the stage. If I'm away for a maximum of two years, I feel something's wrong.
I was only interested in my scene, and I had to go through thousands and thousands of other scenes. I got my scene and I read it many, many, many, many, many times. That was my research.
I was grateful to have two weeks to shoot this one scene in Harry Potter. It's a big, big scene, but they have to deliver. And they have high expectations.
I couldn't get as big as a bodybuilder. I tried to put on as much weight in the right places as I could. My weightlifting was impressive for me, but not for some of the guys I see down at the gym.
Actors use who they are to be someone else, but I would hate to ever think I'm playing myself. It's imagining being someone else that is the key motivating thing for me. So when people want to know about me, it makes me a bit unnerved.
