"Better Call Saul's" second season pivoted on the sibling rivalry between morally compromised but lovable Jimmy McGill (Bob Odenkirk) and his respected, resentful older brother Chuck (Michael McKean).
The show's audience is, naturally, squarely on Jimmy's side. As Odenkirk puts it: "As much as I Iove Michael McKean, Chuck is an ..." (We can't print the observation, but it wasn't a compliment.)
You will get no argument on this point from McKean.
"I say, 'Right on, Bob,'" McKean told The Envelope in a recent video interview. "But I know what it's made of inside there."
That knowledge, McKean says, came from his own speculation on the brothers, their past and the deep source of their antagonism. And it turns out that his guesses were right on the money.
Says McKean: "The very specific pain at the center of it has a lot to do with one simple fact, which is: I made my mom proud. But Jimmy made her laugh.
"I watch my wife knitting," McKean continues, "and it's like watching close-up magic to me. And I think that's what Chuck feels about Jimmy's ease with people. Chuck is a very, very smart man and is a very, very good lawyer, but there is something missing in Chuck and it drives him crazy."
