What happened? French witty comedies are remade in Hollywood, and not the other way around. Which brings us to "Daddy Cool" or better known by its French title, "15 ans et demi", a comedy jointly directed, and adapted by Francois Desagnat and Thomas Sorriaux.This is one of the silliest pictures about the age gap between a scientist father, Philipe Le Tallec, and his newly discovered teen aged daughter, Eglantine. Its idea seems to have been recycled from a composite of American comedies that wastes the talents of one of France's leading actors, Daniel Auteuil, who must have been under the influence of having drunk too much champagne at a fancy place where the creators of this movie took him to have him sign to star in the film.The creators must have targeted the film to a younger audience. There are a few laughs with the recurring appearance of a bald woman, Barbara, who acts as a sort of guinea pig in Philippe's experiment, while the scientist takes time to chat with the spirit of Albert Einstein. Who knows, maybe Hollywood would be interested in doing a remake some day.
