If you've ever seen the TV series Chuck, Adam is the tall, silent dude who growls a lot. Nathan Fillion has been in some shows other than Firefly/Serenity, like Castle (I don't own a TV, are there others?).
Jaynestown was probably my least favorite episode that didn't actually have Reevers. I'm such a girl sometimes.
Alan Tudyk is pretty hot too. Then there's Matt Bomer from White Collar, who is probably the only reason why I watched that show. I don't know if I'd want to hang out with him per se, just rub oil all over his chest.
