My job changes very little because I've found that the more you try to be funny, the less funny you become.
I consider 'Dr. Horrible' a tremendous success. The fact that it won an Emmy I just think lends validity to what we were doing and the point we were trying to make: taking the power into someone else's hands and changing the world.
In all my characters, I try to find an iota of myself, and in Castle, I found a lot. He gets away with a lot, so that's fun.
I've had a long line of failed television programs, pilots that were never picked up, series that didn't go very long. I've learned that there's really nothing you can do. If it's not in my control, I try not to worry about it.
