I'd like to think that we strive in film and theatre to tell great stories, and I believe in the power of storytelling in our culture.

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.

I love playing real characters... if they're not around anymore it's helpful because you won't get sued! But there's so much research involved and I love that part of the process.

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?'

I don't see a difference between playing a performance capture role and a live action role, they're just characters to me at the end of the day and I'm an actor who wants to explore those characters in fantastically written scripts. The only caveat is a good story is a good character.

My agent told me they were casting for the voice of Gollum. I hadnt read The Lord of the Rings, but I read the script and realized what an amazing role it was. I developed a voice for the audition tape, then met Peter Jackson and Fran Walsh at the auditions and fell in love with them both.

Motion capture is exactly what it says: it's physical moves, whereas performance capture is the entire performance - including your facial performance. If you're doing, say, martial arts for a video game, that is motion capture. This is basically another way of recording an actor's performance: audio, facial and physical.
