As we reported earlier, Castle was among the 12 shows cancelled by the networks last Thursday (NBC added another 5 on Friday). Castle, of course, sparked Internet rumors that Nathan Fillion and Stana Katic hated each other after it was announced that Katic would not return for a ninth season. Now, it seems, neither will Nathan Fillion, who took the news in stride over on Twitter.

All things must end. It has been an honor working with the men and women of Castle. I am truly amazed at what we’ve done. Thank you all.

Dear Every Director,
It appears I have an opening in my schedule.

It was in response to the latter that Greg Grunberg offered his less expensive services to directors interested in casting Fillion.

Uh…
Dear Every Director, I am available to play a Nathan Fillion type. https://t.co/DZS7stj4Tz

Fillion’s comeback, uh, lacked teeth.

Curses. Here comes the competition! Bring it, you X-Wing pilot, awesome guy! (That insult needs work, admittedly.) https://t.co/Fl42mO2Alp

Guardians of the Galaxy director James Gunn wasn’t too broken up about the cancellation of Castle, either, especially with rumors of Fillion making an elaborate cameo in Guardians 2.

Good news for me, pal! @NathanFillion https://t.co/aEPRtJsZcS

Meanwhile, Stana Katic kept it classy (although, I suspect her heart was pounding out a triumphant “Suck it, Fillion!) with a handwritten letter that she posted to Twitter, which is kind of like putting a delicious, local, organic hamburger patty inside of a McDonald’s bun.
