Whether he's smuggling goods as an intergalactic space cowboy, or winning our hearts with his cheeky grin as a crime writer, Nathan Fillion ranks right up there with some of our favorite older "more mature" leading men. He's got classic good looks, JUST LOOK at those cheekbones and that perfect swoopy thing his hair does. He's simply irresistible. We're actually positive that in a past life he was Peter Pan, because he's got the whole "I'll never grow up" thing going for him. But we don't mind, because geeky guys who love sic-fi and video games just happen to be our favorites.
