WTOP Entertainment Reporter Jason Fraley chats with “Breaking Bad” creator Vince Gilligan as the spinoff “Better Call Saul” airs its series finale tomorrow night on AMC. They spoke in 2015 when “Breaking Bad” donated props and costumes to the Smithsonian National Museum of American History. You’ll also hear from Aaron Paul, who played Jesse Pinkman; Jonathan Banks, who played Mike; and Bryan Cranston, who showed up to pay tribute to his iconic anti-hero Walter White.
