Diane Kruger, Dany Boon and Tim Roth Lead Netflix's 'Projet K' as Real-Life Nazi-Hunter Film Begins Shooting
Diane Kruger, Dany Boon and Tim Roth will lead Projet K, a Netflix film about the real-life Nazi hunters Beate and Serge Klarsfeld, with cameras already rolling across France, Belgium and Bolivia.
Screen was first to report that the project was underway, on 14 August 2026; Deadline confirmed the casting on 17 August. Kruger and Boon play the Klarsfelds, a married couple who spent decades after the Second World War tracking down former Nazis who had slipped into civilian life. Roth plays Klaus Barbie, head of the Gestapo in Lyon and widely known as the "Butcher of Lyon" — one of the most notorious figures the Klarsfelds pursued.
The film marks a return to Nazi-era material for Kruger, who appeared in Quentin Tarantino's Inglourious Basterds (2009). For Boon, a household name in French comedy, it is a step into dramatic territory. Roth, no stranger to playing menace on screen, takes on a real historical figure whose war crimes included the torture and deportation of Jewish children and resistance fighters.
Yvan Attal directs from a screenplay he co-wrote with Laurent Turner. Attal, best known to international audiences as an actor in films like Rush Hour 3 and The Accusation, has directed several French-language features; this is his first project for Netflix.
The production has chosen locations that trace the Klarsfelds' actual pursuit. Filming is under way in Paris and Lyon — the French city where Barbie operated during the war — as well as in Belgium and Bolivia. Bolivia is where Barbie lived for decades under an assumed name, protected by sympathetic governments, before the Klarsfelds' campaign helped force his extradition to France in 1983. He was convicted of crimes against humanity and died in prison in 1991.
No release date has been announced. Netflix has not said whether the film will receive a theatrical run or go straight to the streaming platform.
The Klarsfelds' story carries a particular weight in contemporary French and German memory. Beate, a German citizen, and Serge, a French-born son of a deportee murdered at Auschwitz, made their pursuit of justice both a personal mission and a public campaign — confronting former Nazis in the streets, publishing photographs and names, and pressuring governments that preferred to let the past lie quiet. Their work led to multiple prosecutions and helped keep the question of wartime accountability alive in European public life decades after the trials of Nuremberg.
A film about people who refused to let that question fade, made by a platform that will deliver it to screens in 190 countries, is a fittingly wide lens for a story that was always international in its reach.
