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.'

My guiltiest pleasure? 'Untamed & Uncut'. Videos of people being attacked by animals. Yeah. I don't know why. I just love seeing guys who say, 'I'm gonna stick my hand in that crocodile's mouth and see what happens.' And then it snaps down on them. There you go - that's what you get! It's a wild animal, my friend.

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 like to say there's certain things you can't take back: One of them is 'I love you,' and one of them is bullets.

It costs nothing to say something kind. Even less to shut up altogether.

I'm the biggest geek of all. Adventure, fantasy, comic books - I can't get enough.

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.
