In addition to verifying the location of the two-film split shortly after Bella's transformation into a vampire, Godfrey confirmed that the birth sequence will attempt to maintain the extremes of the text but, to avoid an R rating, will be "seen only through Bella's eyes".
"She is looking through the haze, " Godfrey says, "experiencing pain and everything rushing around her. We only see what she sees."
Also on the ratings front, Godfrey promises that the key sex scene in the book, "[will] not become soft porn. It is a legitimate and important part of the movie, romantic and sensual."
The producer also added that the second part of the film, due November 16, 2012, will play as more action-heavy than the first part, hitting November 18, 2011.
