There’s been more drama behind the scenes for the FX show "Sons of Anarchy," with creator Kurt Sutter getting into a shouting match this week with co-star Tommy Flanagan, reports Deadline.com.

As previously reported, "Sons of Anarchy" actor Johnny Lewis was recently found dead after allegedly killing his landlady in a gruesome incident.

The fight Wednesday between Flanagan and Sutter didn’t get physical and it’s not the first time the show has been the scene of arguments, the story notes. Sutter had a heated argument with star Charlie Hunnam last year, with the actor later skipping the show’s panel at the Television Critics Association press tour.

The show appeared to be back to normal Thursday, with Sutter back on the set and wrapping production of episode 12 of the show’s fifth season, the piece adds.
