'CSI''s been a great blessing for me. It's been a platform that's allowed me to go around the country and the world, really, and speak on issues of disability, but I've never - I'm a professional actor, so I studied for years; I do theater. I never want to disrespect what got me here.

It is not as though the process of production holds any mystery for me, I know exactly what it involves and I know the predominant concern in shooting one of those things is production values - or as they would say, seeing it all up there on screen.
