Hearing that they recast Jeff the cab driver from season 5 (the guy who recognized Saul in the cab and then harassed him at the mall). Apparently the original actor was not available due to commitments to a different show. A bummer, those buggley eyes were wonderfully unnerving.
You can see and hear the new guy in the teaser below
The Breaking Bad version of Saul is surprisingly murderous. On BCS, Jimmy/Saul is constantly hatching schemes to solve his problems. Non-murderous schemes. I didn't keep count, but on BB he proposes murder as a solution multiple times. It's a little jarring, knowing him as I do now. These are irreconcilably different dudes, BB Saul and BCS Saul/Jimmy
