Who will play Renesmee Carlie Cullen in Breaking Dawn?

Um, Renesmee, nicknamed Nessie ( Bella's daughter) would have to be made with special effects because a young actress wouldn't be able to portray her.

Hi! they won't have an actress play baby renessme but i think i know who is playing pre-teen (or tween) renessme,ME!you don't know me tho!

Nessie can be portrayed by a little five year old but her beauty is so amazing we might she have to hope that there is a breaking dawn film
