Allocine.fr has a really great interview with Melissa Rosenberg about the Breaking Dawn movies. But since it is in spanish, here is the english translation (via His Golden Eyes):
We now know that the last album, “Breaking Dawn” will be divided into two films. Do you already know how you do it?
For me, there is a natural separation in the book. I do not know yet exactly when we will stop in the first film, but in the first part of the book “Breaking Dawn” Bella is human, just married and pregnant while in the second part is a vampire and a mother. So somewhere in this transition, there is a natural separation. But I do not know yet exactly where it will be. It works.
Will you keep the book of Jacob?
No, we will not keep. Eclipse is a good way to introduce the book of Jacob, because in this film, we begin to move away from the simple perspective of Bella. We will see that the newborns, the Volturi … we’re really starting to move away from its point of view alone. So in Revelation, having the vision of Jacob on what will happen almost naturally. We will also maybe you can share other points of view.
The last album is really darker, more violent and more adult than the other three books. Will you keep these aspects in the adaptation?
Yes, absolutely! I think we can make a film more adult, more violent and sexy, while remaining accessible to the youngest. In fact, I do not see gallons of blood everywhere, I do not think this is necessary. I find instead that show everything away the suspense, horror … I would prefer the way all this through Bella. Nevertheless everything is there, we are absolutely not shy from it all. We see for example the love scene between Edward and Bella, and the feathers will be at the rendezvous! (Laughter) As the scene of childbirth, which will be filmed as directed by the director. But we all agree that this scene appears in the film, and it is as close as possible to the book. He should expect a scene of horror!
