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 remember the first day I got there, they started the take and after four takes I was on the ground, on my back, with a banana and a Twizzler in my hand, and my face was green, and they said, "You can't get back on set for another 30 minutes." That was a, "Welcome to Atlanta," and that put everything in perspective.

I took up boxing to get in shape for filming because it's grueling - all the running, the heat, the yelling, the crying that we do.

People think that Detroit is this barren wasteland. While there are parts that are not as nice as others, the misconception is not true. It is definitely not a thriving community in Detroit, but it is getting there. There is a lot of heart and love in this city.

Somehow, I landed The Walking Dead and it's great because it stretches and works different muscles for me, and it really lets me stretch myself as a performer. Now, I'm really excited to flex my comedy muscle. Hopefully, I'll get some opportunities to do that.

You can say that all you want, but even in the little time that I've been in this industry, I've learned that it isn't exactly what you expect, so you've got to have a level head. I thought people would dig it. I thought people would enjoy it. It's AMC. I thought people would be fans. But, I did not think we would be the best new show on television.

I was raised in a Christian household and heard a lot of praise music, so that's what helps me get to an emotional place.
