It was so ridiculous. We were just sitting there, thinking about how ridiculous it was because we literally had stray hairs on us. The camera couldn't pick up all the details, but we had some crazy things. We had huge slabs of fat on us and bits of nails and hair. It was disgusting. But, there's also the beautiful parts of it.

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.

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?"

I can't justify taking one minute of free time for myself. I'm restless to do things. Anything! Hell, I'll watch Top Chef and I think, "God, maybe I could be a chef," I'll watch a dancing show and think, "God, maybe I can be a dancer." I mean, that's how I got into acting. I visited an improv show and thought, "Hey! I could do this." It sounds like arrogance, but I don't think it is... just an ambition to reach out and touch something new.

I’m stupidly curious. I will go and touch anything until I find out that it’s very harmful.

I'm good at keeping secrets, but if it's not something super serious I usually tell people not to tell me because I'll tell someone else.

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.
