Breaking Bad gave television some of its most unforgettable characters but among them, Mike Ehrmantraut was not part of the original plan. He came into the story not because of some grand vision but because Bob Odenkirk could not make it to the set. His other gig on How I Met Your Mother clashed with the filming schedule and the writers needed someone to cover for Saul Goodman. As a result, they built Mike from scratch, which was a quick fix that became one of the show’s strongest pieces.
Mike Ehrmantraut Was Never Meant to Be a Main Character
Jonathan Banks took on the role and made Mike more than a stand-in. However, what was supposed to be a temporary part turned into something essential. His cold efficiency and calm presence clicked with fans and cast alike, and instead of fading out, he stayed. His scenes worked so well that he was folded into the bigger picture, even becoming a key figure in Better Call Saul.
Writers for Breaking Bad created Mike Ehrmantraut as a substitute for Saul Goodman when Bob Odenkirk was unavailable because of a commitment to appear in How I Met Your Mother. https://t.co/kqULvovtLy

Jesse Pinkman Also Survived a Planned Exit
According to The Mirror, Banks was not the only one who nearly missed out. Aaron Paul’s Jesse Pinkman was also supposed to be written off after season one, but changes in the story saved him, and the rewrite gave the series one of its best character arcs.
