Nathan Fillion

"I'm a Halo guy. The Bungie folks were kind enough to have me do a voice for Halo 3. So there's nothing like sitting down to a nice game of Halo and shooting at myself. I like to get online, and the reason I like it is I've got a lot of friends in Canada and New York, all over Los Angeles and at great distances. Sometimes I take off for months at a time to go work, and my social time is on that box. You put on a little headset and unwind with your friends. You hang out, you laugh, it's good times. And when it's all done, you don't have to send anybody home. No one's drunk all your beer. You just say, "good night, I'm going to bed", and it's off and it's done."

- Nathan Fillion on Halo

Nathan Fillion (born March 27, 1971 in Edmonton, Alberta) is a Canadian actor, best known for his lead role in the television series Firefly as Captain (formerly Sergeant) Malcolm Reynolds. In Halo 3, he supplies the voice of Gunnery Sergeant Reynolds, named in homage to Fillion's most famous character. Not only does Nathan Fillion provide the voice for Gunnery Sergeant Edward Buck in Halo 3: ODST, but the character's physical appearance was modeled after the actor as well. Fillion has also confirmed his work as a voice actor in Halo: Reach reprising his role as Buck for a cameo in the level New Alexandria,  and also providing the character's Firefight voice. Fillion also provided the voice for a SPARTAN-IV in the Multiplayer Beta trailer for Halo 5: Guardians.

Trivia

 * Nathan Fillion and Tricia Helfer (the voice of Captain Veronica Dare) recorded most of their voice work for Halo 3: ODST in the same recording booth, which is rare in voice acting.
 * Throughout the campaign and in Firefight his character Buck can repeatedly be heard saying "'Bam!' said the lady", a piece of slang used to emphasize conclusiveness that Fillion thought up and is trying to promote. The phrase can also be heard on Fillion's detective show Castle. "Bam, said the lady," is also the final sentence of the novella Halo: New Blood, which presented from Buck's perspective.
 * Fillion was nominated in the category "Best Performance by a Human Male" for his role as Sergeant Edward Buck in Halo: Reach at the 2010 Spike Video Game Awards.
 * Fillon claims to have invented the radar jammer, for which he was given the previously Bungie-exclusive Bungie Armor permutation in Halo 3.
 * Nathan Fillion references his role as Gunnery Sergeant Reynolds during the song "Better (Than Neil)" from Commentary: The Musical, the side-feature commentary track from Dr. Horrible's Sing-Along Blog.
