HBO is set to premiere a number of new series throughout the rest of the year as we head into the new fall season. To celebrate their impending slate, the pay cable network has released three new teaser trailers, starting with Boardwalk Empire, which returns for Season 5 on September 7. This will mark the acclaimed drama's final run of episodes. Then, returning in November are The Newsroom, back for Season 3, and The Comeback, which is making a comeback of its own with a second season nearly a full decade after it originally debuted. Check out this first look at these anticipated series as the return.
