Nick Vivarelli International Correspondent Sky Italia celebrated its 20-year anniversary on Tuesday by announcing a rich slate of upcoming originals, including a second season of the Italian adaptation of “Call My Agent,” which will see “The White Lotus” star Sabrina Impacciatore joining the cast. The Sky Italia originals slate comprises previously announced high-end drama “M. Son of the Century” by British director Joe Wright, alongside less lavish shows in various stages – most of which have international potential. It underscores how the Italian unit of the Comcast-owned pay-TV service continues to be a major Italian industry driver. While Sky’s German unit, which is believed to be up for sale, has put production on pause, Sky Italia is cranking out Italian originals through the platform’s Sky Studios unit at a steady pace, showing no signs of a slowdown.
