Four months after Aaron Sorkin’s The Newsroom ended its second season on HBO, the cable news drama is officially a go for a third season, which will be its last. It is set to premiere next fall. Sorkin is back as executive producer/showrunner, with former The Office showrunner Paul Lieberstein joining him and executive producers Alan Poul and Scott Rudin as executive producer in Season 3. I hear Lieberstein already had been working with Sorkin on stories behind the scenes. The official renewal comes after months of talks between Sorkin and HBO, with speculation whether Sorkin would come back given his busy feature schedule. But he just turned in his high-profile Jobs script, and will now focus his attention to giving his HBO series a proper conclusion. “The Newsroom is classic Aaron Sorkin – smart, riveting and thought-provoking,” said HBO Programming president Michael Lombardo. “I’m sure this farewell season will be one to remember.” Returning cast regulars include Jeff Daniels, Emily Mortimer, Sam Waterston, John Gallagher, Jr., Alison Pill, Thomas Sadoski, Dev Patel and Olivia Munn.
