Nathan Fillion stars on ABC’s rom-com detective series “Castle” as a mystery novelist who aids a NYPD homicide investigator in solving odd murders. I watched a couple of episodes from season one and found the show to be a little too cutesy for my taste. The show is now on season two and it has reclaimed my interest (it’s on my Netflix queue now) with a recent Halloween inspired outing featuring Fillion in Serenity captain Malcolm “Mal” Reynolds’ old brown-coat duds. If you’re a “Firefly” fan, the following clip is gonna put a big smile on your mug and inspire you to send bags of smelly turds to the Fox executives who made the decision to cancel the space western after airing only 11 episodes.

“Firefly” met its doom in 2002. Series creator Joss Whedon provided closure for fans three years later with the insanely awesome feature film Serenity. Whedon, of course, is the creator of “Buffy the Vampire Slayer,” “Angel,” “Dr. Horrible’s Sing-Along Blog,” and the new Fox sci-fi drama “Dollhouse,” starring Eliza Dushku.

Fillion’s sci-fi/horror cache includes “Dr. Horrible’s Sing-Along Blog,” Slither, and the truly horrific “2 Guys, a Girl, and  Pizza Place.”
