‘Boardwalk Empire’ Season 3 Trailer: Nucky Thompson Goes Great Guns

Steve Buscemi starts things off with a bang in new preview of "Boardwalk Empire"

Looks like the third season of "Boardwalk Empire" will start off with a bang. At least, if the new trailer for the upcoming season of the HBO historical drama is any indication.

In the new snippet from the series, Enoch "Nucky" Thompson (Steve Buscemi) — who shocked viewers by killing off his associate Jimmy Darmody at the end of season two — once again goes into life-snuffing mode, gunning down a shadowy stranger as the rain pours down in a no-doubt symbolic indication of his existential situation.

After he puts a second bullet in his target — this time, as he lies on the ground — yet more symbolism follows. The pistol drops from his hand, what appears to be an engagement ring slips from his finger and onto the rain-soaked ground, and a flower falls from his lapel.

"You can't be half a gangster," a message that flashes on the screen declares.

Season 3 of "Boardwalk Empire" premieres Sept. 16 at 9 p.m. Until then, watch Nucky Thompson get gangster in the video.
