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.

You want to put out a TV show? If you have the money to do it on your own, by yourself, and you have a TV network, you can do it by yourself. But the nature of the beast is, art needs finance. That's how this industry works. So until the Internet becomes our source of entertainment - and watch it, I believe it will - this is how things go.

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.

I love doing 'Castle.' We pump out 24 episodes in 10 months, and we work long hours. We do lots and lots of takes, and everyone there is a talent machine. It is a taxing endeavour to say the least, but when you get into a groove, it doesn't matter if you're tired, it doesn't matter if you're sick. You can do it.

My brain is like a hard drive. Once you start adding new information, you start cutting off old information.
