In a stunning announcement, ABC said on April 18 that Stana Katic will leave the cast of Castle after it finishes its current eighth season. Insiders say it has much to do with her turbulent behind-the-scenes relationship with costar Nathan Fillion.
“Stana Katic and Nathan Fillion completely despise each other,” a source told Us. “They will not speak when they are off set, and this has been going on for seasons now.”
The source also admitted the two stars were forced into couples counseling due to the tension, but it did not stop Katic from choosing to leave the popular series.
Castle has not yet been renewed for a ninth season.
