Brotherhood of the Wolf (French: Le Pacte des loups) is a 2001 French period action horror film directed by Christophe Gans, co-written by Gans and Stéphane Cabel, and starring Samuel Le Bihan, Mark Dacascos, Émilie Dequenne, Monica Bellucci and Vincent Cassel. The story takes place in 18th-century France, where the Chevalier de Fronsac and Mani, an Iroquois man, are sent to investigate the mysterious slaughter of hundreds by an unknown creature in the county of Gévaudan. The plot is loosely based on a real-life series of killings that took place in France in the 18th century and the famous legend of the beast of Gévaudan; parts of the film were shot at Château de Roquetaillade. The film has several extended swashbuckling fight scenes, with martial arts performances by the cast mixed in, making it unusual for a historical drama.
