Here's an exciting sneak peek at an upcoming episode of Castle. The special Halloween episode finished filming recently and this image appeared online. It looks like our loveable Richard Castle is dressing as a Browncoat, looking oddly similar to a character from Nathan Fillion's past!
If ever there was a reason for Firefly fans to start watching Castle, this is it. Tell your friends. Castle airs Monday nights at 10/9 central on ABC.
