Jonathan Banks has joined Bob Odenkirk in “Better Call Saul,” AMC/Sony TV’s upcoming prequel to Emmy-winning “Breaking Bad” that focuses on Odenkirk’s criminal lawyer Saul Goodman, sources confirm to Variety.

Banks will be a series regular on the show, which is slated to premiere in November on AMC.

Conceived by “Breaking Bad’s” creator Vince Gilligan and writer-producer Peter Gould, “Better Call Saul” will chronicle the evolution of Saul before he became Walter White’s lawyer.

Banks was a regular on “Breaking Bad” and played Saul’s trusted private investigator/fixer Michael “Mike” Ehrmantraut. His casting means that Saul will have his helper back by his side.

Odenkirk and Banks are the only actors set for “Better Call Saul” so far.
