In the height of summer 2013, Vince Gilligan, the creator of "prestige TV" phenomenon Breaking Bad, and fellow screenwriter Peter Gould, took a long walk around their offices in Burbank, California. The end was nigh for Breaking Bad, and they had just recently signed a deal to make Better Call Saul, a spin-off prequel series set around Bob Odenkirk"s popular shyster Saul Goodman, a criminal lawyer more criminal than lawyer, more cartoon than man. The only problem? Neither Gilligan or Gould had any idea what the show was about. "We had a very high concept without a lot of follow-through," Gilligan tells BBC Culture. "We would walk around, just cogitate, and say "okay, so what is this exactly?!""
