"I'm a plethora of stolen jokes and kitschy references." — Nathan Fillion

You know, Castle, like anyone else, is a human being first. If you take a human being - especially a vain one like 'Castle' -and you bring in a gorgeous woman and have sparks fly, who can help themselves? What are you gonna do? Sparks happen!

Somebody told me long ago that in acting, it's okay to steal, just steal from the best.

I love hiking in the hills not far from my house. I'm invested in my hikes. Sometimes kids go up there and spray-paint over the signs; I've found a biodegradable paint cleaner, and I'll scrub the signs so they're nice and clean.

I have a trophy case that contains all the action figures ever made of me. It also has items I've stolen from my movies, like three guns and holsters from 'Serenity'.
