Now, screenwriter Melissa Rosenberg has weighed in – and she's all for showing it on screen, though perhaps without some of the gorier details.
"The childbirth – all the scenes, I feel – should be on screen," Rosenberg tells PopSugar. "Would we actually see Edward's teeth through the placenta? I don't think so. I don't think we need to see that."
She adds with a laugh: "If someone needs to see that, I think they should take a look at that."
In the novel, the birth is so difficult that Bella nearly dies, and one book reviewer complained that the scene was so graphic, it "may promote lifelong abstinence in sensitive types."
As the Breaking Dawn film production has been getting closer, Kristen Stewart, in particular, has been curious about that scene. "I haven't seen a script," she told MTV News in January, "but I'm not alone in really, really wondering how they're going to handle that."
Rosenberg, who also wrote the first three films in the series, said last month that she was "deep in the middle" of the script for the two-part Breaking Dawn movie, the first installment of which is due in theaters in November 2011. In the PopSugar interview, Rosenberg says it's been great fun writing the character Bella, in particular, as she evolves.
"I think seeing Bella as a vampire and her adjusting to her powers and embracing them, those are all really fun scenes to write," she says. "Particularly when you picture Kristen Stewart playing her, and the way she's embodied Bella as a sort of awkward, fidgety persona. When she turns into a vampire, all of that goes away."
