The worlds of French cinema and haute couture have been plunged into profound mourning following a devastating traffic collision in western France. The Niort public prosecutor's office has officially confirmed that prominent film producer Nicolas Altmayer and Dior public relations executive Mathilde Favier were the two victims killed in a violent head-on crash.
The tragedy occurred on Monday afternoon around 4:00 PM on the departmental road 938 in Airvault, situated between Thouars and Parthenay.
What Happened on the Road?
According to initial reports and statements from the Niort prosecutor's office, the couple was traveling in a MINI vehicle. While attempting to overtake another car on a three-lane stretch of the road, their vehicle collided head-on with an oncoming heavy-duty truck.
Deputy Prosecutor Nicolas Leclainche confirmed the identities of the victims and noted that an active investigation for involuntary manslaughter by a driver is currently underway to determine the precise circumstances of the crash. Fortunately, the truck driver emerged physically uninjured from the wreckage. Standard post-accident testing confirmed that the driver had consumed neither alcohol nor drugs, and he was subsequently placed in police custody for questioning.
A Massive Loss for French Culture and Fashion
The sudden passing of the couple has sent shockwaves through Parisian high society, where both individuals were heavyweights in their respective industries.
- Nicolas Altmayer (61): A towering figure in French filmmaking, Altmayer produced numerous critically acclaimed and commercially successful movies alongside his brother, Éric. Their impressive filmography includes Brice de Nice, the beloved OSS 117 comedy franchise directed by Michel Hazanavicius, François Ozon's Grâce à Dieu and Jeune et Jolie, as well as Bertrand Bonello’s Saint Laurent. In 2017, the brothers were jointly honored with the prestigious Daniel Toscan du Plantier award by the César Academy.
- Mathilde Favier (56): Widely regarded as one of the best-connected women in Parisian fashion, Favier served as the head of public relations for LVMH's Dior Couture. A historical pillar of the luxury fashion house, she was a beloved and immensely influential figure in the global fashion community.
As investigators continue to piece together the tragic sequence of events on the RD 938, tributes from colleagues, designers, and filmmakers continue to pour in, honoring the extraordinary legacies left behind by both Altmayer and Favier.
