It’s time to go back to Banshee, Pa. — if you dare. The Cinemax action series, which filmed its fourth and final season in the Alle-Kiski Valley and Pittsburgh area, is now available for streaming on HBO Max. “We are home,” actor Matt Servitto, who portrayed Banshee sheriff Deputy Brock Lotus on the show, said on Facebook. “Let the Banshee binge-watching BEGIN!!” “Banshee” and other Cinemax original series, such as “TheKnick,” were not available on HBO Max when the service first launched last May, to the chagrin of their fans and critics who felt HBO was leaving quality content on the shelf.
