Michael McKean, who I and many of yourselves might know as Perry White in various episodes and a few Seasons of Smallville, has been cast as Doctor Gerber, a man befallen with a puzzling medical condition.
Likely seeks legal counsel from Saul, could well end up with some muscular aid for a problem from Mike Ehrmentraut, Professor Hickey in the latest Season of Community.
I'm not sure how Better Call Saul will affect his role on Community, if indeed the half a decade long comedy gets renewed for a 6th Season - and a movie - but hope he still has the stuff he did in Breaking Bad, even though I really disliked Mike myself, for many a reason.
Probably just an episode of the spin-off, but then it might more likely specify that it's simply a guest spot, rather than a recurring role. Could be linked to Madrigal for all we know, and therefore be important, or moreso than imagined.
