<P> The episode marked the final regular performances of actors David Costabile and Jeremiah Bitsui as Gale and Victor . Gilligan considered changing the episode based on audience responses to the third - season finale , `` Full Measure '' , on whether Gale would be killed or not , but ultimately decided against it . During a twist scene in `` Box Cutter '' , Gus slices his loyal henchman Victor 's throat with a utility knife right before Walt and Jesse 's eyes . Esposito said he was concerned about filming the scene `` without really hurting my spirit and my soul '' , and he concentrated so hard that he remained silent and focused during filming , rarely speaking to others on set . The scene was so bloody it made Cranston 's daughter faint during a screening . </P>
