"After receiving thousands (trust me, thousands) of resumes, they selected a group of girls to audition for the role. Also, many young girls (mostly models & actresses) from important Talent agencies were requested to audition as Renesmee. Those lucky girls had the chance to read a couple of lines from the Breaking Dawn script (a draft – not the original script) and say the lines in front of the cameras."
Here are videos from 2 girls who auditioned. *May Contain Spoilers.* It is just a DRAFT of the script but still could contain parts from the official script & what will be in the movie.
First video is from a Della Young.
And second we have a video from Tilly Cheri.
