making guest appearances on the spin-off, but remained vague on which characters were likely to be seen. By the next season, Gilligan said that the show had been on long enough that any reuse of Breaking Bad characters would require more than "just a cameo or an Alfred Hitchcock walkthrough", and that their appearances would need to be essential to the story. Throughout Better Call Sauls run, both Breaking Bad lead actors Bryan Cranston and Aaron Paul regularly said they would be open to reprising their respective roles as Walter White and Jesse Pinkman on the spin-off. However, both maintained that they would only appear if Gilligan found a sufficiently good reason to bring them on the show. Paul previously mentioned the possibility of a cameo during the first season but this fell through. The two would eventually appear together in the sixth-season episode "Breaking Bad", which was named after the original series. Paul made a separate cameo in the next episode; Cranston appeared again in the series finale. Dean Norris, who was also a starring cast member on Breaking Bad, stated he could not be part of the earlier seasons, partly due to his involvement in the CBS series Under the Dome. However, he was announced as a guest star in the fifth season, where he reprised his role as Hank Schrader in the episodes "The Guy for This" and "Namaste". Plans were initially made for Betsy Brandt, another Breaking Bad starring cast member, to reprise her role as Hank's wife Marie Schrader in a cameo on the second-season finale "Klick". However, the writer's room objected, considering the idea to be distracting for audiences. Brandt would eventually appear in the series finale. Other Breaking Bad cast members spoke of the potential of being on Better Call Saul. Before the series began, Anna Gunn mentioned a "talk" with Gilligan over possible guest appearances as Skyler White. Bill Burr was set to return as Patrick Kuby in the fifth-season episode "Dedicado a Max", but scheduling fell through due to him needing to attend to a personal matter. After the series ended, Gould mentioned his desire to bring back Gunn, Norris, Esposito and RJ Mitte for the finale, but he and the writing staff could not find a proper way to have them fit into the story. Filming Principal photography for Better Call Sauls six seasons took place from June 2, 2014,
