Tragedy Strikes: Beloved French Producer Nicolas Altmayer and Dior Exec Mathilde Favier Killed in Car Crash
French producer Nicolas Altmayer and Dior executive Mathilde Favier have died in a car accident in western France, leaving the film and fashion industries in mourning. Altmayer was a celebrated producer behind major French films, while Favier was an influential figure in international fashion public relations. Both were highly respected and their sudden loss is a profound shock to their respective fields.
Nicolas Altmayer, a highly acclaimed French producer, and his partner Mathilde Favier, a distinguished public relations executive for Dior, tragically died on Monday in a car accident in western France. Altmayer was 61, and Favier was 57. The couple's sudden passing has sent shockwaves through both the French cinema and international fashion industries, where they were both incredibly influential figures.
The fatal accident occurred around 4 p.m. on a departmental road in Airvault, located in the Deux-Sèvres region. According to the Niort prosecutor’s office, their vehicle “hit a heavy goods vehicle traveling in the opposite direction while they were overtaking another vehicle.” Deputy prosecutor Nicolas Leclainche confirmed that an investigation for involuntary manslaughter by a driver has been initiated to thoroughly determine the exact circumstances of the collision. Le Figaro reported that Altmayer and Favier were en route from Cabourg to the Île de Ré, where Favier owned a residence.
Nicolas Altmayer was recognized as one of France’s most prominent independent producers. Alongside his brother Éric Altmayer, he co-ran Mandarin & Compagnie, a production house celebrated for its diverse filmography, which spanned from commercially successful French comedies to critically acclaimed films by some of the nation’s leading auteurs. His extensive credits include popular titles such as Michel Hazanavicius’ “OSS 117: Cairo, Nest of Spies” and “OSS 117: Lost in Rio,” both starring Jean Dujardin, as well as the comedy “Brice de Nice,” also featuring Dujardin. Altmayer was also a steadfast collaborator of acclaimed filmmaker François Ozon, producing a long string of his works, including “Young & Beautiful,” “The New Girlfriend,” “Frantz,” “By the Grace of God,” “Summer of 85,” and “Everything Went Fine.” His impressive portfolio further extended to Bertrand Bonello’s “Saint Laurent” and Julia Ducournau’s “Alpha” and the Charles Aznavour biopic “Monsieur Aznavour,” starring Tahar Rahim. In recognition of their significant contributions to French cinema, Nicolas and Éric Altmayer were honored with the César Academy’s prestigious Daniel Toscan du Plantier Award in 2017. Numerous industry figures paid tribute to Altmayer; filmmaker Fabien Onteniente hailed him as “a great producer,” Ozon expressed “shock and sadness,” and Franck Gastambide described him as not only his producer but also his “mentor, the father I would have wanted to have.” Canal+ boss Maxime Saada and CNC president Gaëtan Bruel both underscored his passion, loyalty, and immense loss to French cinema. Nicolas Altmayer is survived by four children.
Mathilde Favier was an equally influential figure, particularly within the international fashion and celebrity spheres. She began her career at Prada, where she was instrumental in establishing the Italian fashion house’s Paris press operation, before joining Dior in 2011. At Dior, she ascended to the role of director of public relations for Dior Couture, a position that saw her working closely with many of the brand’s high-profile ambassadors and celebrity guests, including Natalie Portman, Rihanna, Jennifer Lawrence, Anya Taylor-Joy, Camille Cottin, and K-pop star Jisoo. Le Figaro lauded her as a “solar and influential” personality within the fashion industry. Favier was also the sister of Dior Joaillerie creative director Victoire de Castellane. In 2024, she co-authored “Mathilde à Paris,” a personal guide to the French capital, with journalist Frédérique Dedet. Additionally, she founded the association Esthétique & Cancer, which is dedicated to supporting individuals undergoing cancer treatment through beauty and wellness programs. Bernard Arnault, chairman and CEO of Dior parent company LVMH, praised her dedication, passion, energy, and talent, while Dior CEO Delphine Arnault described her as “an exceptional woman whose infectious joy, talent and loyalty were exemplary.” Producer Elizabeth Kesses fondly remembered both Altmayer and Favier, stating they “shone like the sun, both creatively brilliant, natural connectors and most of all the kindest of souls.” Mathilde Favier is survived by two children.
The joint passing of Nicolas Altmayer and Mathilde Favier represents an immense and irreplaceable loss across the French cultural landscape, leaving deep voids in both the film and fashion communities they so significantly shaped and enriched.
