I was going to be a High School teacher. I was studying at the University of Alberta in Edmonton, up in Canada. I was also acting in a wonderfully supportive theatre community in Edmonton. There's a lot of support for theatre there. So, I was having a great time, but I didn't consider acting as a serious career initially, because even the most successful actors that I know in Edmonton are not super successful. Acting over there is just not a success-oriented career.

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.

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 think people imagine that I have about five scripts sitting in front of me and I say, 'I think I'm going to go with the super hero thing and after that I'll wrap it up with some more sci-fi and then do a romantic comedy.' But it doesn't quite work out that way.

My first Comic-Con was when I first met Joss Whedon: He introduced me to that world and I'd never been to a convention before that. He and a bunch of the 'Buffy' and 'Angel' writers were all going down in a big van and he invited me along.

It's a thrill to be a fan amongst fans.

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.
