The Breaking Bad spinoff show Better Call Saul has been given a second season before the first has even aired, AMC has announced.

Bob Odenkirk stars as crooked lawyer Saul Goodman in the upcoming show, which concentrates on the character's life before the events of Breaking Bad.

The series is being made by Breaking Bad creator Vince Gilligan and writer and producer Peter Gould.

The first, 10-part season of Better Call Saul began filming in New Mexico earlier this month and will air in early 2015. The newly confirmed, 13-part second season will debut in early 2016.

AMC President Charlie Collier commented on the news: "Production on Better Call Saul is underway and we could not be more proud of nor more excited about the work to date.

"We join the fans in eager anticipation for this series and today we happily confirm that our initial Saul order is for two seasons and a total of 23 episodes."

He continued: "We have a strong history with Vince, Peter, Bob, the studio and so many involved with this production; we are enjoying the process on Saul and all share a focus on making it a true television event. No half measures."
