I think they would have to keep it as one movie.
because if they broke it up, they would have to leave it on a serious
As far as i can think, they would have to cut it off just before bella goes into labour (and so there'd be no climax at the end), when jacob sees nessie for the first time aka end of book 2, or when bellas transformation finishes. I think all of these endings would leave a lot of people unsatisfied, like when in the golden compass they cut it off just before the whole bit with the opening to the new world and roger dying, etc.
Then again, a cliffhanger would be good for business, cos people would come back for the next movie.
I think for Nessie they could not show her much at all until when they fast forward the four months, then you could use a four or five year-old actor. the baby would be okay
with cgi, but I don't know. Malaz
with the lean body they'd just use padding and corsets and stuff, wouldnt they?
and bella as a vampire . . . the problem is that they're probably trying to make bella as appealing and good looking as possible now
to attract more people, so that would be a problem . . .
They could just give her a new haircut
