Melissa Rosenberg was the woman responsible for adapting a screenplay from the Twilight: Breaking Dawn novels and she admits that it has been very gratifying. Melissa finished her involvement in the movies a couple of years back so has moved on from the project already.

Rosenberg told Collider, “I actually finishing writing these about two years ago, and then worked with (director) Bill [Condon] for a while, before they started shooting. So, all of us behind the camera have been moved on for at least a year, if not two. But, I remember finishing it and it was very gratifying.”
She added, “The story came to a close and I felt like, ‘Okay, it’s done.’ I was ready to move on, at that point. I wasn’t like, ‘Oh, thank god!,’ but I took a moment and took a breath, and then was really excited about telling some different stories. I felt complete."
