'Desperate Housewives' is an ensemble cast, where I played a tertiary character. I made a lot of great friends, but that show didn't keep me very busy.

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.

I don't spend a lot of time online. My mother's really good at picking out if she sees a really great review, and she'll forward it to me. She's like my little Internet filter. It's always nice to see something going up; if I want to find something on Nathan Fillion, I do know where to look, but I've got a nice little delivery system in my mom.

I got amazing training both with Theatre Sports... back in Edmonton, Alberta - I can't give those people enough credit - and the daytime drama I did. Incredible training, both of them.

I had a Ford F-250. It was a big ol' farm truck, but it wasn't a rig. That's about the biggest I've ever driven. That's what I drove back and forth to high school. I was a poor guy, and it was a truck that my uncle owned and let me drive because I had no money.

I had an Indiana Jones fedora that I loved. I don't know what happened to it. I don't know where it went. Wish I had it back. Whoever's got it, you suck.

I have a lightsaber at my front door for home protection. I have an 800-watt electric skateboard that I use to run errands in my neighborhood. It can go about six, seven miles, so depending on how much time I have, and how much I have to carry home, I'll take it really far. I love that thing.

I have a trophy case that contains all the action figures ever made of me. It also has items I've stolen from my movies, like three guns and holsters from 'Serenity'.

I kind of found a niche for myself after 'Firefly'. I found something that I enjoyed doing and that I did well, but as far as how I seek out a part, it's always different. It's always something that lights you on fire when you read it. It might be just one scene, it might be one line that defines the character for you.

I like making sci-fi movies because I like watching sci-fi movies. I like watching horror. I like being in a horror movie. I'm a fan. My perspective's a little different just because I get to participate as well as spectate.

I love hiking in the hills not far from my house. I'm invested in my hikes. Sometimes kids go up there and spray-paint over the signs; I've found a biodegradable paint cleaner, and I'll scrub the signs so they're nice and clean.

I love what I do. And why not be nice? I mean, I've seen people who work and they're apparently not enjoying it, and they're making sure everybody knows it.

I remember when TiVO first came out I was all about TiVo. I came home and that thing was frozen, and I thought 'This is awful. This is the end of the world'. Then I unplugged it, and I plugged it back in, and still frozen. It was paralyzing. I called them. They said, 'Just unplug it longer.' Fixed. But it also taught me I'm an addict.

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.

I think TV has been a little bit irresponsible in how they portray these people because homicide detectives are not brooding, tortured souls who are stained with the stink of the city and who have blood on their hands. They are real, live people that are incredibly entertaining.

I told myself a while back, 'Love what you do, but don't fall in love with what you do.' That way you won't be brokenhearted if ever it gets canceled five episodes in - which has happened to me.

I want my job to include a little adventure, a little more of a heightened reality than what I'm actually living. And 'Castle' has that. He gets this opportunity to tail these homicide detectives, and he's driven by that. He's a little immature, but he's obviously loving life.

I was a huge comic book fan as a kid. The only problem I had with comic books is how expensive they got. I didn't have a lot of money, so I had to be very specific about what I wanted to collect. I think they're all somewhere in the basement of my folks' house.

I was attending the University of Alberta. I was going to be a high school teacher, like my parents. I failed - no, I didn't fail a class, I just barely passed. I really didn't try. It was Canadian history, through the plays of the time. My God, those were boring plays.
