After the announcement that Stana Katic would be leaving Castle at the end of season eight, there was a flood of reports stating the chemistry between Katic and Nathan Fillion definitely didn’t extend off-screen. Behind-the-scenes it seems that Katic and Fillion did not get along very well in the later seasons especially.
