ABC hit show “Castle” has ended last month but fans haven’t get over it yet and it seems like some of the cast as well.

So what’s keeping “Castle” lead stars Stana Katic and Nathan Fillion busy post-“Castle”?

Katic, who played Capt. Kate Beckett is currently enjoying traveling. She recently took to Instagram to share her wine tasting experience in a place called “Bibich Wines” on the outskirts of Skradin, Croatia, Movie News Guide reported.

MNG noted that the actress is set to star in several movies, which are expected to be released this year.

Fillon, on the other hand, is reportedly in the process of making “Castle” season 9.

Movie News Guide wrote in a separate report that Fillion, who portrayed mystery novel author Richard Castle, has signed up for “Castle” season 9.

The ABC police procedural show was canceled after season eight allegedly because of the ongoing feud between its lead stars – Stanic and Fillion. It was earlier reported that Fillion has been bullying Katic and she was once seen crying on the set.  Stanic then announced that she is leaving the show after season 8.

According to Deadline, Fillion has inked a new deal with ABC for Season 9.  ABC and ABC Studios reportedly secured the deal with a condition that they will not bring back Katic.

Apparently, the network has also signed a deal with Seamus Dever (Detective Ryan), while talks are going with Molly Quinn (Alexis), Susan Sullivan (Martha), and Toks Olagundoye (Hayley) to come back for the ninth season.

ABC Entertainment President Paul Lee has earlier teased a possible “Castle” spinoff. Lee revealed at the recent Television Critics Association winter previews that he is already exploring spin-off and other opportunities should Katic and Fillion not return after season 8, TV Guide wrote.

“We’d love for Castle to keep going for many years to come.There are a lot of conversations going on about how we can do that. I don’t want to give glimpses to where they go, but there are lots of good ideas in there. I’m feeling optimistic that we’ve got some good ideas,” Lee said.

No official confirmation as of yet whether there will be “Castle” season 9 or a spinoff.
