The new film from Thierry Klifa, The Richest Woman in the World (La femme la plus riche du monde) will soon be making its world premiere at Cannes.

The NYT interviewed Klifa on his latest movie, which stars the legendary Isabelle Huppert.

At the Cannes Film Festival, a Story of Love, Money and Scandal

The world’s richest woman falls under the spell of a younger man. In the space of several years, she gives him more than $1 billion in cash, annuities and works of art — until her daughter steps in and reveals all in what turns into an international scandal.

That’s the true story of the French billionaire Liliane Bettencourt, heir to the world’s largest cosmetics company, L’Oréal, and her longtime friend and confidant, the author and photographer François-Marie Banier. A fictionalized version of the saga — “The Richest Woman in the World,” starring Isabelle Huppert — will have its world premiere at the Cannes Film Festival, which runs through May 24.

A disclaimer at the movie’s start says it is “very loosely” inspired by real-life events and contains elements of “pure fiction,” including private exchanges between family members. And the director Thierry Klifa has made sure to change all the names. Yet the movie still hews very closely to the actual events (as recounted in a three-part documentary available on Netflix, “The Billionaire, the Butler, and the Boyfriend.”)

Admittedly, Huppert looks nothing like the real-life Madame Bettencourt, who was recognizable by her heavily lacquered coiffure and strictly tailored suits. In the movie, Huppert has silky shoulder-length hair and a much younger look. She comes across as a playful Parisienne who is seduced by the flamboyant Fantin (the fictionalized version of Banier) and allows him to change everything: her clothes, her art collection, her life.

In a recent video interview, Klifa discussed the scandal, why he became interested in it, and why he chose Huppert. The conversation, translated from French, has been edited and condensed.
