In Breaking Bad, the character Mike Ehrmantraut was actually created because Bob Odenkirk, who plays Saul Goodman, was unavailable to film a scene due to his commitments on How I Met Your Mother. In the Season 2 episode “ABQ,” the script originally called for Saul to go to Jesse’s apartment after Jane’s d3ath to help clean up the situation and instruct Jesse on what to do. However, because Odenkirk couldn’t make the shoot, the writers quickly created a new character to handle the scene. That character became Mike Ehrmantraut, played by Jonathan Banks. What began as a practical last-minute solution turned into one of the most important additions to Breaking Bad. Mike went on to become a major figure in the series and later a central character in Better Call Saul, proving how an unexpected production problem helped create one of the franchise’s most beloved characters.
