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 think that acting can be a very pressurized existence. So when I'm not working, I spend very loose and unpressurized time and I like to meet people who have a similar attitude.

People keep inviting me back. It's nice to work with the same people when you've had a good time previously, and this is one of those cases.

No one wants to see a person on TV who's super-ultra-cool. That's Superman, that's a thing of the past. Heroes are now flawed, and have terrible tempers, you know? They're real people.

I tell you, 'Firefly'? Best job I ever had. Heartbroken when it was canceled, but had it not been canceled, I never would have gotten 'Serenity'. I think 'Serenity' is the most incredible thing I've ever been able to actually get my hands on and do. I can't even tell you how much love I have for that project.

I think my printing to this day looks like the printing right out of a comic book. Actually, I always wanted to be in a comic book. I watched cartoons when I was a kid, too, and both comics and cartoons lit fire in my imagination. This realm holds a lot of interest for me, a lot of passion for me. So to be comic-ized, yeah, that's cool.

Castle isn't really affected emotionally by murder. He's thrilled about, 'Oh, my God, I wonder how this happened?'
