Nathan Fillion finally has a hit that isn’t a cult hit!  Well Castle isn’t so much a hit as it is a procederial with a steady viewership.  Personally, I’m big fan of the show, and as always, Fillion flaunts his wit and impeccable timing.  In the clip he makes his former boss proud by donning the Captain Mal duster from Firefly while referencing Buffy, and a little Underworld thrown in there for good measure.  And all in under two minutes!  I’m sure Whedon is beaming in between frowns due to Dollhouse’s eminent death.
