the movie "Rock'n Roll" shot by Guillaume Canet is quite entertaining yet disclosing film of what it's like to be an actor in modern day. characters have their real names, action happens on a daily basis and that gives movie documentary esthetic. Marion Cotillard plays her role in an extremely good way as always.the movie is full of funny scenes.All in all it show how over-commercialized is film industry and how it destroys your identity and the way of living.
