You don't go - oh this is a motion capture role, I'm going to employ this method of acting. We don't have anything to hide behind when we're doing this.

What you can do with visual effects is enhance the look of the character, but the actual integrity of the emotional performance and the way the character's facial expressions work, that is what is going to be created on the day with other actors and the director.

I can get on with all different sorts of people, and I never feel homesick, particularly, or I've never felt kind of patriotic towards any one country.

I think even back as far as 'Lord of the Rings,' there was always the chance that 'The Hobbit' would be made, even way back then. Of course at that point, Peter Jackson didn't probably think at that point that he'd be directing it.

I remember kind of doing early acting and thinking, "God, they don't paint behind the sets." It's a bit of a shame, really - "Oh, what's on the other side of this wall? Oh, you can see the plywood." I was really disappointed. I just thought that these things were real, from watching things as a kid.

I stayed in Baghdad every summer until I was 14. My dad's sister is still there, but many of my relatives have managed to get out. People forget that there are still people there who are not radicalized in any particular direction, trying to live normal lives in a very difficult situation.

When I played Gollum in 'Lord of the Rings,' if I was climbing up the side of a mountain, which I physically did, you know, I was on every single occasion swimming through streams, all of that, that wasn't captured. That was filmed on 35 millimeter, and for certain of those shots, it was rotoscoped and painted over.
