Terence Winter

The HBO show began its final season Sunday. Terence Winter says he wrote the Prohibition-era dram in part to work with Martin Scorcese. It has "something I couldn't possibly ... pass up," he says.

HBO's Boardwalk Empire, set in Atlantic City in the 1920s, is about organized crime in the era of Prohibition. Series creator Terence Winter, an Emmy Award-winning writer for The Sopranos, details his enduring fascination with New Jersey gangsters.
