Personal Quote:

I don't think I could play a character that I couldn't relate to somehow. I'm not unfamiliar with frustration, anger, shame, helplessness and a load of other emotions that make up our psycho-soup. I try to focus on that frustration, that sense of unfairness, and multiply it. See more »


Although always friendly onset, he keeps private and mysterious habits apart from his younger Lost (2004) co-stars, who often get together for wild parties when not shooting. He keeps this enigmatic aura so they will regard him similarly to the way they regard his mysterious character Locke. See more »
