'Breaking Dawn' Screenwriter Is 'Deep In the Middle' Of Script

'One of the biggest challenges is it's really thick with mythology,' Melissa Rosenberg reveals to MTV News.

Although the first of its two installments is more than a year from hitting theaters, the forthcoming "Breaking Dawn" already has Twilighters trying to predict how much of the books will make it to the screen. MTV News recently went in search of some inside scoop from screenwriter Melissa Rosenberg. Like you, we wondered just how much of the 754-page book we can expect to see.

"I'm deep in the middle of it," Rosenberg said of her progress on a script. "I've been working on it for several months now and it's a bear, but it's exciting."

Rosenberg, who has written the screenplays for all three "Twilight" films, also revealed that the "Dawn" adaptation is proving particularly challenging because of the sheer number of characters and the dense mythology behind it all.

"One of the biggest challenges, it's really true with all the novels, but probably more so with this one, is it's really thick with mythology, there are a lot of characters," she said. "The characters expand with the arrival of Carlisle's friends. It's really about who do you pull forward, where do you focus?"

Rosenberg said that though the story always centers on the three main characters — Edward, Bella and Jacob — she wants to make sure to explore the body of myths that fuel the vampire series. "That's the dance I'm playing throughout the entire thing," she said.

As for the cast of the "Twilight Saga," they seem to have welcomed news that the final chapter in the series will be a two-part story.

"I didn't want to read the script that was just one [movie]," Kristen Stewart recently told MTV News. "It would have lacked so much because you just couldn't cram the story into one. At least that was my opinion, so I'm really excited."

"Eclipse" opens June 30, and the first of the two "Breaking Dawn" films is scheduled for a November 18, 2011, release.
