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.

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.

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.

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

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

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.

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.
