A lot of things are going to be left out, I'm sure. I think they could easily fit Breaking Dawn into one movie. New Moon had good effects, so it will probably be good. They might have several actresses for Renesmee. I think they can make Bella just as good a vampire as the rest of them. I've seen a picture from victoria's last fight scene, and chances are it won't be any worse than James. I don't know about the third wife thing...it's not really nessiary, so probably not, but you never know. The same way as the other ones I'd image, with the running. Hopefully they'll do special effects instead of wires for the running. They'll probably tone down Victoria's death. IT will be from a distance, and Bella might be disoriented, like in the first movie. Kristen Stewart says she's looking forward to playing a pregnant lady. I'm not a big fan of the final book, but I'm really looking forward to seeing it on screen.
What I was thinking was, so far both movies have been rated PG-13, and the last book has sex in it, so I'm wondering how bad those scenes are gonna be. Because there are a lot of young girls that will be very disappointed if they can't see the last movie, lol.
