For fans of Breaking Bad this is the greatest news of the week. For those nonfans, Iâll cut to the chase real quick: This fella named Jonathan Banks is going to guest star on Parks as Benâs dad. Mike Schur explained the casting to HitFix: âWe were working the character description of Benâs dad and I said aloud, âHe should act like Mike Ehrmantraut.â So somebody said, âWell, why canât we just get Jonathan Banks?ââ Great job, somebody. (Breaking Bad Spoiler Alert) Letâs all just agree to imagine that Mike didnât get the chemical bucket treatment and instead hopped into a car and drove to Pawnee, Indiana to visit his lovely son and his lovely sonâs lovely girlfriend. And then that can become a new TV show, which also features a back from the dead Gus Fring.
