"Breaking Bad" spinoff  "Better Call Saul" may follow in its parent's footsteps by ending after the sixth season.

Star Giancarlo Esposito, who plays drug lord Gus Fring, dropped the news in an interview with Collider. 

Production recently started on Season 5 of the AMC drama, and when asked if it was the final installment, Esposito said, "It's tricky with [co-creator Vince Gilligan]."

"If you look at the 'Breaking Bad' model, he said five years, five seasons ... but it was really five and six," he added, referencing the final season being split into two and broadcast a year apart.

So, like flagship, like spinoff. "There will be six seasons," Esposito continued. "It seems like that's the way, the comfortable way, to end this show."

AMC declined to comment and sources told The Hollywood Reporter that the show's endpoint is not set in stone. So far, the show is only renewed through Season 5.

Capping the show after six seasons does seem like a good plan. That would put its episode count close to that of "Breaking Bad." And the timeline would make sense, with two seasons to detail Jimmy's (Bob Odenkirk) transformation into Saul, what happens to Kim (Rhea Seahorn), the further descent of Mike (Jonathan Banks) as a criminal fixer, and the consolidation of Gus's power. And there'd be time to flash forward to find out what happens to Jimmy/Saul in the future, when he's hiding out as Gene the Cinnabon manager.

Season 5 of "Better Call Saul" is slated to premiere sometime in 2020.
