Presented out of competition at the 2025 Cannes Film Festival, 'The Richest Woman in the World' is another example of a cinematic and television trend: fiction inspired by true events treated with varying degrees of creative license. Director Thierry Klifa avoids banal television naturalism, focusing instead on the complex relationship between the protagonist, Marianne Farrère, and Pierre-Alain Fantin. The film evolves from a comedy of manners into a parable about the devastating power of money, anchored by powerful performances from Isabelle Huppert and Laurent Lafitte.
