Nate does acting work. Besides background and stand-in work on locally-filmed movies (21, The Great Debaters, The Town), he’s also done commercial work (like this one: http://www.youtube.com/watch?v=46EeI5uNjWw) and starred in local theater productions of Neil Simon’s Fools (here’s a review foolsreview_crimson) and the world premiere of the play Half-Married.
Also, here’s a headshot of him: Nate Johnson, headshot.
