While it came as little surprise to the fans of Stephenie Meyers' original books, the success of Twilight caught Hollywood and the rest of the world by storm when the first adaptation arrived in theaters late last year. A big part of the credit for the movie's crossover success must be attributed to screenwriter Melissa Rosenberg, who rendered the romance of Bella and Edward in dimensions that more than die-hards (or more accurately, Twi-hards) could understand and appreciate.

The Twilight sequel New Moon comes to theaters next Friday and offers even more tortured teenage romance than before, as well as a wealth of mythology about vampires, werewolves and other monsters that inhabit the series' supernatural universe. Cinematical recently spoke to screenwriter Rosenberg at the film's press day in Los Angeles; in addition to discussing the process of putting together a satisfying sequel, she talked about subjecting Bella to the universal disappointment of a bad break-up, and examined what audiences might take away from this latest installment in the series.

Cinematical: Is there an emotional core or some central theme that was guiding you through writing New Moon, or do you see this more as an installment in a larger narrative?
