A mere two days after its smashing series premiere, HBO has renewed the Scorsese/Winter production Boardwalk Empire for a second season.  The debut of the Prohibition-era drama averaged 4.8 million viewers, making it HBO’s most watched premiere since 2004’s Deadwood.  Says Michael Lombardo, President of HBO Programming: “All the ingredients aligned for this one, from Mark Wahlberg and Steve Levinson’s initial pitch, to Martin Scorsese’s enormous contributions as director and executive producer, to the genius of Terry Winter and the expertise of Tim Van Patten, to a stellar cast led by Steve Buscemi.  The response from the media and our viewers has been nothing short of amazing.”

Boardwalk Empire airs Sunday nights at 9PM on HBO.
