HBO and Martin Scorsese are officially business buddies.

The premiere cable channel has confirmed that they’ve picked up 11 more episodes of Scorsese’s Prohibition-era drama, “Boardwalk Empire,” based on the strength of the pilot that he directed.

The series, set in 1920s Atlantic City, chronicles the life of part-politician, part-gangster, Nucky Thompson (Steve Buscemi).

The pilot episode was penned by “Sopranos” writer Terence Winter and shot in and around New York in July.

Depending on his schedule, Scorsese, who is an executive producer on the series, may direct more episodes down the line. Production is expected to begin later this fall. —
