I still buy actual books. The smell, having it in your hands - there's really no substitute.

Whatever our bedtime was as kids, we could stay up an extra half hour if we were reading. My parents didn't care as long as I was under the spell of a Stephen King or a Douglas Adams. Now I read in bed. I read at work. I read standing in line. It's like, 'Hello, my name is Nathan and I am a reader.'

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.

The truth is I'm a dork. I collected comics. I still love cartoons. I'd rather be at home on a Friday night than out at some club… My sense of humor is that of a geek. My likes and dislikes are that of a geek. I've memorized every crappy sci-fi movie there is, but still haven't seen Schindler's List.

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 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 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.
