While promoting Welcome to the Rileys Kristen spoke to 24 Frames (LA Times) about Bella in Breaking Dawn:
"This one's really good. This one really goes there, finally," said the actress who plays the iconic Bella Swan of "Breaking Dawn." "This one is like the forming of a family. You see everything really come to fruition because I feel like [Bella] has sort of gone through an accelerated growth period."
Because their child is half-human and half-vampire, Bella’s pregnancy is riddled with complications -- all leading up to a dramatic birth scene, in which Edward tears open Bella’s stomach with his teeth to save their baby.
There has been speculation about how the graphic scene will be depicted on screen. Stewart acknowledges it's a "crazy concept," also describing werewolf Jacob's hearing "vampire teeth against vampire skin" during the childbirth scene.
Just how that will play out on screen, though, has yet to be determined. "I've seen the script," which tracks closely to the book, she says. "But it depends on how they shoot it."
Stewart, who was speaking to 24 Frames to promote her new independent drama "Welcome to the Rileys," said she thinks her "Twilight" character has been misunderstood. “Bella’s criticized sometimes for being, like, you know -- I don’t know, selfish and overly emotional and silly and frivolous and annoying and young,” said Stewart. “That’s sort of like a very judgmental way of looking at it."
