Better Call Saul is now over after six seasons on AMC, but how did it all begin? Of course, we all know that the series is a spinoff of the hit show Breaking Bad, created by Vince Gilligan. Gilligan, who also co-created Better Call Saul with Peter Gould, spoke about both shows in a new interview for The Rich Eisen Show. During the conversation, Gilligan discussed how exactly Better Call Saul came to be.

As Gilligan explains, the idea for the spinoff had actually come about as a joke very soon after Bob Odenkirk debuted as Saul Goodman in the second season of Breaking Bad. As Odenkirk had been doing so well with the character, a crew member had jokingly remarked about a "Saul Goodman spinoff," and while everyone laughed it off at the time, the concept always resonated with Gilligan and Gould.

"The joke became, it kind of planted a seed in our heads, and we thought, you know, that would be fun to do a spinoff. It wasn't this logistical, 'Gee, what we need to do next is spin somebody off, who do we pick?' It kind of grew from naturally wanting to keep the crew together, and thinking Bob's character is just fun to write, just plain fun."

As Breaking Bad drew closer to its ending, Gilligan and Gould only grew more confident in doing their Better Call Saul spinoff series. The only issue was that they weren't quite sure what to do with it beyond having the series focus on Saul Goodman. In fact, even by the time Gilligan and Gould had signed on to do the spinoff with AMC, they still were working things out creatively. Gilligan says how the series was first envisioned as a half-hour comedy series that would make light of the kooky criminals that seek Saul's services at his law office. There could have even been name comedians brought in to play some of these characters.

"There was a show... Dr. Katz, it was animated, it was a really funny show. Basically, comedians coming on a talking to a psychiatrist about their problems. We thought, very derivative of that excellent show, we were saying, 'Why can't it be people walk into Saul Goodman's iconic office?' And we could get a bunch of comics. We could get all these great folks coming in with their legal issues. We talked about that for a week or two, Peter and I."

There had been thoughts of doing Better Call Saul since season 2 of Breaking Bad, but it's a different situation with the spinoff series ending. Gilligan and Gould, who were deep into their work on Better Call Saul when Breaking Bad ended, are not currently working on any more content related to Breaking Bad. Both plan to pursue new projects, but as Gilligan told Rich Eisen, there still remains a possibility that he might one day revisit that world, even if it's not in the near future.

"I kind of feel like I got to try something new. I've got to prove to myself I'm not a one-trick pony... Never say never. I don't have any, not a scintilla of plans, to do anything else with any of that world right now... But, if I get my ass handed to me with this new show..."
