Giancarlo Esposito, when you take everything into consideration, is probably the most likely person to be crowned the King of Prestige TV. Not only was he one of the big bads in “Breaking Bad,” but he is currently a villain in not one, not two, but three separate major series, “Better Call Saul,” “The Mandalorian,” and “The Boys.” That’s one hell of a lineup. And if Esposito has his way, he’d add yet another new series to the list, following the early days of his “Breaking Bad” villain, Gus Fring.
