Boardwalk Empire 1

"You can't be half a gangster."

This new trailer for the season three of "Boardwalk Empire," which returns to HBO on Sunday, September 16th at 9pm, is all stylish rain, stylish violence and a stylish sense of impending doom focused on Steve Buscemi's Nucky Thompson.

The Terence Winter-created period drama, as implied by the scene below, has to deal with the aftermath of a major character death in its new season -- it seems Nucky's going to have to make some adjustments in his life.
