Will There Be a "Firefly" Reunion on ABC's "Castle"?
Two of Serenity`s crew members are going from the skies to the streets of New York, as Adam Baldwin reunites with Firefly comrade Nathan Fillion for a guest spot on the latter`s ABC series Castle.
Baldwin, who recently finished a five-season run on NBC`s Chuck, will play Ethan Slaughter, who is described by one TV Guide reporter as "a rough and tumble cop from the city`s gang unit who lands a case that Castle is desperate to follow."
However, the crime novelist will discover "a dirtier side of police work" -- forcing him to decide how far he`ll go to solve a case, as working with Slaughter will put him "in the line of fire like never before."
Fillion and Baldwin first worked side-by-side as Captain Mal Reynolds and mercenary Jayne Cobb on Joss Whedon`s cult sci-fi Western series Firefly in 2002, and reprise their roles for the 2005 big-screen follow-up Serenity.
Fillion portrayed Caleb in the final episodes of Buffy, the Vampire Slayer in 2003, and Baldwin appeared in the final episodes of spin-off Angel in 2004.
The episode on Castle is set to air sometime this spring.
Castle airs Mondays at 10p on ABC.
