Breaking Bad co-star Jonathan Banks will be reprising his role as private investigator Michael “Mike” Ehrmantraut in the prequel series Better Call Saul. I loved this character in Breaking Bad, and it's awesome that he'll be back.
He will join Bob Odenkirk, who is back as the unflappable criminal lawyer Saul Goodman. The series will chronicle the evolution of Saul before he got involved with Walter White and his meth business. Banks will be a series regular, so we'll be seeing him around a lot, which is great! These are the only two actors officially attached the new series so far.
Mike is a former Philadelphia police officer who worked as the Head of Corporate Security at Los Pollos Hermano and enforcer in Gustavo Fring’s crystal meth operation. As you know, he later got involved with Walt (Bryan Cranston) and Jesse (Aaron Paul), which didn't turn out well for him, as he was ultimately shot and killed by Walt while trying to get out of the business.
