Few modern scandals have captivated France as the astonishing events surrounding Liliane Bettencourt, the billionaire heiress to the L’Oreal fortune and doyenne of Parisian society. Now writer/director Thierry Klifa has freely adapted the incredible story into a captivating dark comedy, featuring a jaw-dropping, tailor-made role for one of France’s most iconic stars. Marianne Farrère (Isabelle Huppert), the head of the Windler Group, is the richest woman in the world. Pierre-Alain Fantin (Laurent Lafitte) is a vivacious dandy, writer and photographer. After meeting on a photo shoot, the two quickly become inseparable. Their friendship – one where Pierre-Alain is only too happy to take financial advantage – surprises, amuses, intrigues, and eventually unsettles the billionaire’s entourage and family. Most of all, Marianne’s daughter (Marina Fois) struggles with her mother’s sudden complicity with this younger man, but her husband (André Marcon) and loyal butler (Raphaël Personnaz) share her concerns. Surreptitious queries soon transition into a private investigation, resulting in extraordinary ramifications for all involved… With several twists too good to spoil, THE RICHEST WOMAN IN THE WORLD makes the most of its fabulous ensemble cast, but Huppert and Lafitte simply eat up the screen. This wildly entertaining film became an enormous box-office hit in France for good reason.
