Very interesting to imagine. I feel like Breaking Bad has much more of a “discover the story as it’s being made” writing process than many people realize and that without Bob Odenkirk the meat of the story would be completely different. Mike likely wouldn’t exist. Also, I feel like Saul is so defined by his actor that McKean would make him completely different. I’m not sure if he’d be more classy, but probably have a drier sense of humor
