Okay, Wyck Godfrey has given some answers about Breaking Dawn
Where will the first movie end?
Well he said that in the first movie we will be seeing the wedding, the honeymoon and the birth. It ends just before she is turned by Edward, so I think that means we don't see him biting her.
Will we see things from Jacob's point of view?
Yes, we will. It will break off from her and go into Jacob's point of view. And if I remember correctly I once saw a photo of the wolf pack sitting in a recording studio, maybe they were recording conversations for when he's in his wolf form? Although we're not sure when it breaks into his POV, probably once Bella returns from her honeymoon, like in the book.
Breaking Dawn being R rated?
“It would be a crime against our audience to go R-rated." However, "this is based on a much more mature book. We need to progress and be more sophisticated.”
That is what he said specifically, although that doesn't really give us an answer, but I think we can be 100% sure that it won't be R, and that it will be PG13 and for the countries that don't have that rating, only PG it would be M, which is open for everyone to see.
How much will we see on the honeymoon?
"It does not become soft porn. It is a legitimate and important part of the movie, romantic and sensual."
Again, I'm not sure how to interpret this answer, but with it being PG13 or M I believe it would stay fairly covered up, but it has been said before that we'll be seeing feathers.
