Onstage, I enjoy the thrill of live performance - there is no substitute for that rush. On camera I enjoy the crafting of a scene, the widespread creative marksmanship happening all around you for every second of footage. Onstage you can suddenly feel solitary, like it's all on your shoulders, while on camera you feel like there are so many people working with you on every shot. Those are each unique and gratifying challenges.

I have been exposed to a great deal of the issues surrounding PTSD, but what I have learned that is most relevant to my work on Mercy Street is that this illness is timeless. We didn't have a diagnosis for PTSD in the Civil War like we do today, but those men and women definitely suffered from similar psychological wounds as our men and women in uniform do today.

The toughest parts of the shooting schedule for me are the days between working, when you've nothing to do but wait. There is only so much time you can spend on a script before it becomes so rehearsed that your performance becomes rigid and immovable on the day of, so one has to occupy one's time in some fashion. For me, those interim days are usually spent exercising, exploring, learning to cook something edible, and working on my own creative endeavors.

The "stage" on which you perform in film and TV is much smaller. Moving your eyes across the frame is equivalent to crossing from stage right to stage left in a big Broadway house. Coming from a theatrical background and temperament, this is something I am still learning. However, I think ultimately your responsibilities to the character and the overall story are the same in both mediums, so my approach felt very similar.

I think the only productive way to approach characters, and frankly people in life, is through empathy. The minute we call someone a villain, we are choosing to part with empathy and that can be a slippery slope, both as an actor and a human being.

I perform regularly with a theater company called Outside the Wire who take performances of Greek tragedy to American-military audiences around the world to create discussion about PTSD and soldier suicide. It's one of the greatest things I've ever been asked to do as an actor.
