We've seen the teaser and the first trailer for HBO's "Boardwalk Empire," and now there's a new trailer that is by far the most gangsta. The show, created by "The Soprano's" writer Terence Winter and exec produced by Martin Scorsese, who also directed the pilot, looks like "The Soprano's" but with fedoras, speakeasies, and hot lather barbershop shaves. Steve Buscemi is the new Tony Soprano, so we're trading in a weight problem for a dental one, but he appears just as menacing and short-tempered as the wheezing Mafia boss. He plays "the undisputed ruler of Atlantic City and town Treasurer, Enoch “Nucky” Thompson, who is described as “a political fixer and backroom dealer who is equal parts politician and gangster and equally comfortable in either role." Get ready for "Boardwalk Empire" to come at you like gangbusters this fall on HBO. And for God's sake, hide your barrels of bathtub gin. I recommend the bathtub. Check out the new trailer after the jump.
