i enjoyed this movie for the most part. my problem is with the director. on the criterion dvd, there is a behind the scenes extra, and she talks about how she doesn't tell the actors/actresses what's happening until they were told to do it on set, making it all the more shocking to them...what broke my heart was when the young lady playing anais, confessed that she didn't want to do her nude scene, but the director insisted on it...she made the comment that "catherine gets what she wants." how in the hell could you ask a 13 year old girl to bare her breasts, against her will? that's despicable to me...
Today teenagers are not the same, they are hardly the same biological species comparing to teenagers hundred years ago. They know, see and understand more than you can imagine. More than you and me (unless you are a teenager yourself).
And therefore they know that when they sign anything, they have to read it first. I don't believe many of them would be so blinded by the possibility to become a star, that they wouldn't check what it means. And even if so, there are still parents to give suggestions and control what's going on. And the same later, when the filming is in progress, and maybe some changes may appear. There is always a freedom for everyone to say NO to anything. You can say NO to smoking, drinking, swearing, playing basketball, singing, jumping from the cliffs, cutting hair, taking drugs, eating ice-cream. You are free to be nude and to refuse to be nude.
If the girl was really cheated and noone told her there would be any nude or any other scene she didn't want to make, she could have said no. And I believe producers would make a pressure on the director, because changing the main actress during filming is extremely expensive, so I believe any problematic scene would be skipped.
Finally, to stay on the topic. There is a very convincing rumour that Natalie Portman was asked for a nude scene in Leon and she refused. Jodie Foster did the same in similar age. Brooke Shields and Virginie Ledoyen did their nude scenes. All the movies were successful, and all of the girls made a great, still lasting (and growing!) career. So accepting or refusing nude scenes didn't influence either on movie or their careers. And I took just a few examples probably known to most of readers. Therefore, I see no reason to believe Breillat is to be blamed.
In some countries female face, or at least female hair is not allowed to be exposed in public. So, it is obvious that every female face, especially if hair is seen, is by all means a body double. All the actresses are in fact men in disguise.
