‘Castle’ Cast: Where Are They Now? Nathan Fillion, Stana Katic and More

Castle captivated audiences for years — and its abrupt cancelation and alleged on-set drama has stayed with fans since its 2016 end.

The ABC drama premiered in 2009, bringing together author Richard Castle (Nathan Fillion) and Detective Kate Beckett (Stana Katic) as an unlikely duo. As their partnership progressed, Castle and Beckett became an unstoppable crime-fighting team.

Unfortunately, even their undeniable onscreen chemistry couldn't prevent the series from being cancelled. In April 2016, it was announced that Katic would be leaving the show in season 8, reportedly due to budget limitations. However, an exclusive source informed us at the time that Katic's departure was a result of her offscreen tension with Fillion.

According to an insider, Nathan has continuously treated Stana poorly for an extended period. Another source revealed that things escalated to such an extent that Stana and Nathan were required to attend couples counseling together.

Although Katic's representative initially denied any problems with Fillion, they later confirmed her departure shortly before ABC canceled Castle in May 2016. The final episode of the show aired during the same month.
