Now that the heat is officially on, and Gyp Rosetti has launched an attack on Nucky Thompson's alcohol enterprise, "You'd Be Surprised" how quickly things are going to spiral out of control for 'Boardwalk Empire's Atlantic City.  This Sunday will see the fifth all-new episode of the season, as Nucky petitions Arnold Rothstein (Michael Stuhlbarg) to get involved with the ongoing feud, while simultaneously taking care of some business for his new-found lady love Billie Kent (Meg Steedle).  But who's doing the dirty work, according to these new clips from "You'd Be Surprised?"

Almost halfway through 'Boardwalk Empire's third season, and we can already tell that everything will end bloody.  After last week's tense "Blue Bell Boy," there won't be any turning back between Nucky Thompson and Gyp Rosetti, whose firm entrenchment in Tabor Heights makes it impossible to do business.

Enter Nucky's already-tenuous relationship with Arnold Rothstein, who hasn't received his shipment of liquor, but is still petitioned to get in the fight.  Will Rothstein be willing to start a war in New Jersey, let alone New York?  And how does Chalky White (Michael K. Williams) fit in, who shows up with his associate Mr. Purnsley to menace Eddie Cantor (Stephen DeRosa)?

Check out the all new 'Boardwalk Empire' season 3 clips from "You'd Be Surprise" below, and be sure to tune in Sunday for the rest of the action!
