The Crimson Rivers (private collection - Eng Sub) 8/10 though IMDB 6.9/10
In this movie Jean Reno (my most favourite French actor) is a murder detective/commissioner who must follow the footsteps of a brutal killer within the secrets of a classist college in the French alps.
Fantastic French scenery. A great plot with twists and turns. Though my partner guessed the murderer just before I did. The English could make a great version of this movie. Just hope that the Americans don't get hold of it as they will make a silly, gorified hash of it, where you will know the result in the first quarter.
