Improv as an actor makes you present in the moment. You listen, you're attentive. You're not acting so much as reacting, which is what you're doing in life all the time.

I kind of fell backwards into acting. I was studying to be a high school teacher. I look now and I understand completely, or actually barely, how much work it is to be a teacher. It's an incredible amount of work.

I told myself a while back, 'Love what you do, but don't fall in love with what you do.' That way you won't be brokenhearted if ever it gets canceled five episodes in - which has happened to me.

It's a trap I've fallen into earlier in my career - trying to be liked. Don't do it. When I watch TV and I see someone trying to make me like them, acting cute or quirky or goofy, I'm not impressed. Don't act like America's watching you. Just latch onto your character. Characters are flawed. Be unlikeable. Be flawed. Be a person.

I tell you, 'Firefly'? Best job I ever had. Heartbroken when it was canceled, but had it not been canceled, I never would have gotten 'Serenity'. I think 'Serenity' is the most incredible thing I've ever been able to actually get my hands on and do. I can't even tell you how much love I have for that project.

You know, I endeavor to be more like my older brother. He's very magnetic. He's actually very much like 'Castle' in that people are attracted to him, and just want to be near him. You want to know where my brother is in a crowded room? He's the guy with the crowd around him.
