FX is extending the current fourth season of flagship drama Sons Of Anarchy, the highest-rated yet for the biker series, with a pickup of one additional episode. That will bring the total fourth season order to the Kurt Sutter-created SOA to 14 episodes. The series’ Season 4 finale will now air on December 6. “Creatively, this has been Sons’ best and biggest season ever,” said FX’s EVP original programming Nick Grad. “Kurt asked us to consider adding an extra episode to fully close this current chapter of the Sons saga. By adding the extra episode, it wraps up a magnificent season in extraordinary fashion. This is a real bonus for fans of the series.”
