For me, Nathan Fillion will forever be Captain Malcolm Reynolds, one-time Browncoat, and captain of the Firefly-class Serenity, on the unfortunately short-lived Joss Whedon-directed TV series, Firefly.

Later on, I discovered that Nathan (along with several of his Firefly co-stars) had done voiceover work for the animated series Justice League Unlimited- as the gun-totin' Vigilante.

A few years later, he goes on to do voicework for video games, more notably on the Xbox's Jade Empire (as Gao The Lesser), and then on Halo 3 (where he identifies himself as Sergeant Reynolds).

Now in post-production: Nathan Fillion is voicing the role of Steve Trevor in the latest DC direct-to-DVD animated feature, Wonder Woman, which is slated for release later this year. Can't wait to get my hands on that one.

Five Factoids About Nathan Fillion:

• ABC picked up a pilot for a comedy Nathan wrote. The project is called Repo Brothers, which should be out in several months. In the meantime, he is playing the title character of a new ABC crime drama called Castle, which we would be seeing in 2009.
• Remember the Spielberg movie Saving Private Ryan (1998)? Well, Nathan was the Minessotta Private Ryan- not the Ryan Captain Miller's team of rangers were looking for. I saw it again on HBO.
• According to IMDb.com, Fillion wanted to be a high school drama teacher. In college he majored in art, and minored in drama while pursuing an acting career on the side.
• Nathan claims to be descended from Confederate Lieutenant General Jubal A. Early. When told this, Joss Whedon created a bounty hunter by the name of Jubal Early for the Firefly episode "Objects in Space."
• You can check him out as the self-centered and slightly-cheesy Captain Hammer on the Joss Whedon online musical "Dr. Horrible's Sing-Along Blog", with co-stars Neil Patrick Harris and Felicia Day.
