You dread that there will be real problems during filming.

I veer away from trying to understand why I act. I just know I need to do it.

Going to the movies was a big event in my youth. My father would be the initiator - he'd have me put on a jacket to see a film.

He's really sort of the devil. He's completely emotionally detached. He has no empathy. You find that in psychopaths. It's about power with Voldemort. It's an aphrodisiac for him. Power makes him feel alive.

I went out to Mount Kilimanjaro, which I thought was very beautiful, but there were a lot of people there.

I got to read some writings by serial killers, and they got inside my head. They were quite disturbing. I read disturbing stuff about that very detached way of manipulating people to do things.

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.
