Nathan Fillion: EW’s Geek God!

Castle star Nathan Fillion is Entertainment Weekly’s cover star this week!

Here’s what the 39-year-old Canadian actor, who’s also starred in Serenity, Firefly, and Buffy had to share:

On his character, crime novelist Richard Castle: “He’s got some money and nice tastes. He’s not an a–hole, but he is a bit of a prick.”

On how his fan bases differ: “Castle fans – I’ll say 75 percent of the time – are women, and they light up. They go [eyes and mouth open]. They get really excited. Firefly fans will see me, do a double take, stop, nod, and say, ‘Captain’ with an air of ‘I know what you’ve been through. I’ve been there too.’ A guy did it to me in a furniture store the other day. I was walking by, and he saw me, stopped, stood up straight, and said, ‘Captain,’ and I nodded and said, ‘As you were.’ ”

On staying true to his inner geek: “It’s easy to keep the geek fan base stoked by simply remaining true to the inner geek. I just continue to be excited by the things I am excited by. I love sci-fi. I love computer games. I love technology. I like flashlights that are really small but really bright. If it has buttons, batteries, performs some kind of unusual function – yeah, I got it. I want it.”
