Rene Zellweger

On election day I watched the movie "Brigit Jones' Diary" with Rene Zellinger and Hugh Grant. In this movie Rene is a chunky person with ample boobs and fanny. We see her in her panties a few times and get a good look at all that flesh. She seemed comfortable with that body. About a month ago, I saw the movie "Chicago" in which Rene played a dancer that was as skinny as a stick, even anorexic. She danced up a storm in this movie and hit all the necessary beats. The dancing duets were worthy of standing ovations. Of note was the lack of boobs, a male could have played her part. She had no fanny at all, though she was not shown in her panties. I did see her in "Cold Mountain" but she wore a lot of clothes in that movie. At that time, I did not know of the immense transformation that she would do, if that is what it can be called. How did Hollywood do it? What does the real Rene truly look like?
