The first episodes filmed for season two was actually the sixth episode aired; "Redux" finished principal photography shortly after filming for "Tempest" ended, which was just before the crew went on their summer break. With "Redux" filming directly after the season one finale, the cast and crew were required to forgo the immediateness of their summer break so they could film; it was not aired in season two until the sixth scheduled airdate because of complications that arose after filming had ended. During the summer hiatus, after director Chris Long finished working on his cut of the film, it was decided the episode needed more visual effects. Since the shots were not originally planned, Entity FX, the show's special effects contractor, had to create completely new shots.
