Twilight star Kristen Stewart fears her character's horrific baby delivery scene in Breaking Dawn won't be graphic enough for fans of the book.
The actress' human character Bella gives birth to a half-vampire baby in the new film - and she regrets the fact that filmmakers had to play down some of the action described in Stephenie Meyer's book.
Stewart often wonders just what director Bill Condon could have done if he was allowed to make an R-rated movie.
She tells Entertainment Weekly, "In some ways it was disappointing not to be able to really go there... The birth is really effective, and I've heard it really hits you in the face, but what it could have been? It could have been shocking and grotesque, because that's how it was written in the book.
"I would have loved to have been puking up blood."
