"Box Cutter" is the fourth season premiere of the American television drama series Breaking Bad, and its 34th episode overall. Written by series creator Vince Gilligan and directed by Adam Bernstein, "Box Cutter" originally aired on AMC in the United States on July 17, 2011. The narrative follows protagonist Walter White (Bryan Cranston) and his partner Jesse Pinkman (Aaron Paul) as they face repercussions from drug kingpin Gus Fring (Giancarlo Esposito) for killing Gale Boetticher at the end of the previous season. Meanwhile, Skyler White (Anna Gunn) breaks into her husband Walter's condominium to investigate his sudden disappearance, and Marie Schrader (Betsy Brandt) struggles to help Hank Schrader (Dean Norris) recover from his injuries. 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 Gale's 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. A major theme of "Box Cutter", and the entire fourth season, involved Walter's gradual change into a darker character who becomes more proactively violent and dangerous. The episode also illustrates Jesse's moral decline and feelings of guilt over his killing of Gale, and Skyler's growing involvement in Walter's illegal activities. The episode received positive reviews and was watched by 2.58 million households, according to Nielsen Media Research. Until the fifth-season premiere, "Box Cutter" was the most watched Breaking Bad episode in the series' history and the third-highest-rated season premiere for any AMC show, after the first two seasons' premieres of The Walking Dead. In 2012, Gilligan received the Writers Guild of America Award for Best Episodic Drama for his work on this episode. This marked his second win for individual work on Breaking Bad, along with his award from the pilot episode in 2009.
