However, as of late, it is still unclear whether or not his partner, Stana Katic, will return to play the role of his onscreen partner.

Fillion's other co-star, David Amann, will no longer return next season, an ABC spokesperson confirmed.

Additionally, series creator Andrew W. Marlowe and executive producer Terri Edda Miller will step away from their current duties on "Castle" to focus more on development, according to TV Line.

In a previous interview with the publication, Amann talked about the future of "Castle," now that Katic's contract is up this spring.

"Obviously, we're prepared for whatever comes along, and we'll adjust as necessary. In the meantime, we'll just make the best show that we can," he said.

Back in November, Katic also gave her two cents on the show's future and suggested that it would be best to end the series when the cast is no longer complete and the plot has nowhere else to go creatively.

"For me, it's about art over finance, and as long as we're creating something that is compelling and that has somewhere to go, then we're good to go. And when we find that we're not, then it's time for everyone to pack up and move onto the next thing," she explained.

As of late, ABC has not yet confirmed whether or not "Castle" will return for season 8.
