Q: How do you differentiate Jimmy McGill and Saul Goodman in your head, scene to scene? When are they the same, when are they different?

A - Odenkirk: “Saul is pretty shut down, emotionally. Jimmy is an open floodgate of emotions. But life is battering Jimmy down, and he is getting colder, harder, more defensive. Soon he’ll be Saul, a misanthropic manipulator who views people as pawns in a game he’s trying to ‘win’ - remind you of anyone?”
