What I learned, in the two months that we shot, I don't think I could have learned in two to four years of drama school. It's invaluable to me, and that's been the most fun. It's been nice to let this be a learning experience in everything.

I think there are fans who love the genre to begin with, and there are fans who love the comic book to begin with, but fans of the comic book aren't necessarily fans of the genre. There are obviously a lot of those people who love both, but I'm not a huge fan of that genre, personally.

The biggest challenges are in the same vein. It's about retaining all that stuff. Also, the physical stuff is not as easy as we originally thought. I play a lot of sports and I remember saying, "Oh, I'll be fine, running around or doing anything."

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.

I grew up in Michigan, so I played hockey, football and basketball. I played a little bit of lacrosse, too. My brother played more lacrosse and ran track.

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?"

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.
