I watched the preview after I watched the movie, I see a girl holding a bow and arrow dressed in white. When i looked at the cast I see what i think is her, the character "nu" what happened to her? Unless I missed it ?(watched it 3x) she never appeared in the movie. Just the preview, is she in the director's cut or whats the deal? Awesome movie.. but it just left me wanting more back story on the characters and it looks like there might be.. over all excellent movie.
