Nathan Fillion Had The Best Reaction To Castle's Cancellation

For the first time since 2009, actor Nathan Fillion will be without the show that turned the fan favorite actor into a TV mainstay, as ABC decided to cancel Castle just as Season 8 is coming to a close.

Not that Fillion was only calling out directors to heed his words for his post-Castle career.

And youll notice how he is calling out directors there, and not TV showrunners or even a more generic producers.
