Nucky Thompson
Played by Steve Buscemi
Equal parts corrupt politician and gangster (and equally comfortable in either role), Nucky Thompson is in the right place at the right time to capitalize on the opportunities presented by the passing of Prohibition. The shrewd and charming Treasurer of Atlantic City is beloved by its people, a consummate glad-hander and back-room dealer who also maintains strict control of the illegal activities running rampant in "The World’s Playground."
