Vince Gilligan and Peter Gould's Better Call Saul is back for its fourth season, with its talented ensemble back in the fold. Picking up after the shocking, tragic ending of season 3, the series will deal with the fallout of Charles McGill's death, and how that impacts his brother Jimmy's transformation into the one and only Saul Goodman. Elsewhere, audiences will continue to follow the ongoing cartel dealings with characters like Gus Fring and Nacho. As some may recall, the third season ended with Hector Salamanca suffering a stroke after Nacho switched out his heart pills with fakes.

The departure of towering talent Michael McKean (who played Chuck for three seasons) leaves a void Saul will never truly be able to fill, but there are several gifted thespians on AMC's hit drama. As the show's latest season revs up, we've assembled a cast and character guide to help viewers keep track of who's who in both the main and recurring casts.
