When I first joined SAG, there was another John Reilly. My dad was John Reilly, too, but growing up I was John John. Nobody in life calls me John C. It's more like, 'Hey you, Step Brother!'

I listen to a lot of Chicago blues, I suppose. It reminds me of growing up, I guess. But I'm also obsessed by close-harmony groups. Actually, I'm fascinated particularly by brother duos, how they blend together. The Everly Brothers, the Stanley Brothers, The McQuarrys. There's something inherently magical about harmony.

Surprising people is the key to career longevity for someone like me.

I considered a lot of different jobs as a kid. I thought about becoming a priest or a lawyer. My father had a big linen-supply business and I considered working for him. What dawned on me was: 'If I'm an actor, I get to do the fun parts of every job!' Without having to go to four years of law school.

Not all artists have a responsibility to be socially or politically aware, but they do have a responsibility to make great art. They have to find some truth and put that in their music.

My experiences in the military, the private sector, and as a congressional staffer were at times almost enough to drive me crazy. Writing offered the all-too-often-cited creative outlet.

Mine is not an autonomous imagination.

Mostly, I would like people to ask other writers about the craft of their writing so we could learn from one another. We ask movie directors why they chose to use certain lights and angles and speeds of film, but most of the time, we ignore the craft of a writer.
