Dianna: Castle scoop! Not involving Castle and Beckett…I want happy scoop! So you know how Castle is doing a Firefly-esque tribute in an upcoming episode? Sounds like they are currently casting for…well, Nathan Fillion! Gabriel Winters is described as an actor who quickly rose to fame playing Captain Max Richards on a hit sci-fi series. Of course, unlike Fillion, this leading man spiraled out of control after his show went off the air with booze and one-night stands. Castle’s Firefly-themed episode, titled “The Final Frontier,” is the seventh episode of the new season.
