A term for fans of the Canadian actor Nathan Fillion who currently stars in the ABC hit TV show Castle as the mystery novelist Richard Castle. Another term would be Fillionaire. Fillion is also known for playing Captain Malcolm "Mal" Reynolds in the sci-fi TV show Firefly and movie Serenity and Captain Hammer in the online web-series Dr. Horrible's Sing-Along Blog. Every Fillionite knows how double rainbow Nathan is and will always support him.
Nathan Fillion is my idol therefore I am a Fillionite
