Having read the source material, I had to have drawn from that. As a fan, I wanted to remain true to that character, but it was really cool because, as we were figuring these characters out, I realized that there was a lot more backstory, rather than what I had gotten just from reading the book. Glenn doesn't really get much of a backstory there. He's just seen as this kid who is put in this situation, not knowing where his mind-set is, but then you slowly see him start to develop.

If you work in Chicago in the improv scene, anyone is happy for you if you get a job.

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

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 felt like I've needed to ask my parents up until about four years ago about everything. They have helped me tremendously, I came out of college with no debt. Everything they made, they just poured into my education.

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.
