'Boardwalk Empire' Season 5 Releases First Teaser Trailer: Final Season of Acclaimed HBO Show Premiers In September, Watch Here [VIDEO]

Fans of the HBO hit "Boardwalk Empire" will be saying a bittersweet goodbye to the show with the airing of its final season this September. HBO has just released the first trailer for season 5 of "Boardwalk Empire."

Announcing the final season of the show, HBO president of programing, Michael Lombardo, said, It has been an incredible honor to bring this powerful and groundbreaking series to our subscribers. Terry Winter has created one for the ages."

There is no specific reason given for why "Boardwalk Empire'' is ending with season 5. Cannavale may be one of the reasons "Boardwalk Empire" is ending its run after five seasons.  One of the prevailing theories as to why Winter and HBO came to such an amicable and sudden agreement on when to close out the show is that they are both eager to begin production on another period drama: The '70s-set rock 'n' roll series.

Winter has said, " We're thrilled to get the go-ahead for a fit season of "Boardwalk Empire. After much discussion with my creative team and HBO, we've decided to wrap up the series after such a great run and look forward to brining it to a powerful and exciting conclusion."

For audiences, the primary concern now is how Winter and his creative team plan to wrap things up. At the end of season 4, Nucky (Steve Buscemi) was eager to throw in the towel, Eli (Shea Whigham) had been exiled to Chicago, and Chalky White (Michael K. Williams) retreated to Maryland to mourn his daughter and pick up the pieces of his business that'd been left in tatters, thanks in large part to Dr. Valentin Narcisse, played by Jeffrey Wright. 

The other big news for the fifth and final season of "Boardwalk Empire" is that it will start seven years after the end of the last season. Michael K. Williams, who plays Chalky White, says that Season 5 will take place in 1931,"The Depression has set in. The days of the shiny shoes and fancy suits are long gone."

Though the show will certainly be missing some important events from its seven-year jump, it also allows showrunner Terrence Winter to jump right to the final days of Genovese crime boss Joe Masseria (Ivo Nandi), who was assassinated in 1931 as part of a power-grab by one-time ally Lucky Luciano (Vincent Piazza).
