The only thing I've really liked her in was Lemming - I forget the director's name. Was it Dominik Moll? Anyway from around 2005. That Moll is one to watch. Forget Ozon.
But back to Charlotte -
Unfortunately she inherits her father's looks and her mother's talent. She's adored in France as top celebrity daughter, although I lean more to Julie Depardieu there.
But when you've got those kind of connections, sooner or later you hit the right projects.
