Confidence. That's huge as an actor. Confidence can get you a long way. Maybe it's a cultural thing, being Korean, but my first reflex has always been to exude humility - but it doesn't help you in acting. For acting, humility isn't the best thing. It'll weaken your work. So it's a head game for me. "Can I really be confident in knowing my skill set is down? Can I perform like I own this role?"

Yeah, it's scary. During filming, it wasn't just jitters from being the newer guy there or the greenest guy there. It was also fear of not messing up such an important character.

If you ask any of the other actors, they'd probably say nice things because they're nice people, but I was always like, "Oh gosh, I hope I'm doing this right." I was very hard on myself, and I continue to be. That's why it's sometimes hard for me to digest watching myself on television. There is some pressure.

I know a lot of people who say, "I reluctantly watched the first episode because I don't really like zombies and that stuff, but I was pleasantly surprised by the characters and the drama of it all." I think that's what keeps people coming back and brings new watchers to the show. What the show does is cross many, many different viewerships.

I'm not much of a horror fan. When it comes to ghost stuff and demon stuff, I can't watch that.

The most fun thing about doing the show is that, as a nerd, the fun has been in learning and having it be like a grad school for me, every day. Every moment is a new experience. Every conversation is a new gain.

I was more into music, before I got into college. In high school, I used to play guitar and sing. I did a lot of that. But, when I graduated and went to college, I remember my freshman year and this girl from across the hall, who is one of my good friends to this day, had a brother who was in the school improv team. We went to go watch a show and it blew my face off.
