Nathan Fillion Used to Make ‘Castle’ Co-Star Stana Katic Cry On Set – Report

According to reports, seemingly good guy Nathan Fillion is actually a not so nice guy, allegedly driving his Castle co-star Stana Katic to tears on numerous occasions.

Which would perhaps explain her departure from the ABC crime procedural after eight seasons.

“Stana would cry on set because Nathan was such a bully to her. Stana would go in her dressing room and cry,” squealed an insider, explaining, “A lot of people who work on the show don’t like Nathan. It’s not just her.”

Added another informant, “The friction was very evident. Nathan has been nasty to Stana for a long time. Stana was a pro, just wanted to get in there and do her job.”

The on screen couple were even reportedly sent to counseling to deal with their issues.

A rep for Katic however denies the claims, saying that the actress has “had absolutely no issues” with Fillion.
