"Le pacte des loups", translated into Brotherhood of the Wolf ?
I haven't see the movie last year (I rarely see any movie at all), but a many friends of mine saw it. Some liked it a lot, others not at all, because of the kung-fu style (the movie maker is the one responsible for Crying Freeman IIRC), very un-historic. (The Beast of the Gevaudan has became a legend, but there was something, or someone, who has killed a lot of people. Today, there is an attraction parc in the Gevaudan, featuring many wolwes from all around the world. It's of course one of the favorite spot for Werewolf : the apocalypse players)
