Nathan Fillion

Canadian actor Nathan Fillion had already made a name for himself in the daytime television world with a three-year stint on ABC's "One Life to Live" (1968-2013) when "Buffy the Vampire Slayer" (Fox, 1997-2003) creator Joss Whedon introduced him to primetime audiences in the cult sci-fi Western, "Firefly" (Fox, 2002-03). Fillion reprised his role in the big-screen spin-off, "Serenity" (2005). Mild-mannered with a subtle sense of humor and a guy-next-door realism about him, Fillion earned notice for co-starring in independent features, including the horror comedy "Slither" (2006) and the indie romantic comedy "Waitress" (2007), opposite Keri Russell. Fillion was courted to star in a number of TV projects, including the action series "Drive" (Fox, 2007) and the romantic comedy/drama "Castle" (ABC, 2009-16), and while the former vehicle proved short-lived, his glowing reviews and appeal with female audiences on the latter show revealed that if paired with the right project, he exuded an undeniable star quality.
