I'm surprised nobody in the States has heard of it. I don't think it even has a release date.
Does anyone know if there is an English translation of the book? I'd love to read it.
Just a bit of trivia: three of the actors in A Very Long Engagement are in this movie. Jerome Kircher, Tcheky Karyo and Gaspard Ulliel.
