Boardwalk Empire is coming back!!!! The Season 2 premiere of the HBO original series is set to air sometime in September. My guess is it will take True Blood's spot at the end of their season. God I can't wait for this series to come back on the air. This is probably one of if not the best series on television (and no that isn't because I'm from AC). Check out the trailer below and get psyched! I know I am.
