‘Lupin’ Part 4 Brings Omar Sy’s Gentleman Thief Back October 23 — and This Time There’s a Copycat

The official Part 4 trailer opens with a warning: “We have a new Lupin.” It’s the cruelest possible twist for a man who just spent four years in prison trying to be done with the name.

PARIS — Netflix has set Friday, October 23, 2026 for the premiere of Lupin Part 4, with all eight 45-minute episodes arriving at once. It is the longest gap between chapters in the show’s history — Part 3 debuted in October 2023 — and, at eight episodes, the most extensive installment of the series. Omar Sy reprises his role as Assane Diop, the gentleman thief who became one of streaming’s first genuine non-English global phenomena. Netflix stated in its logline: “Omar Sy reprises his iconic role as Assane Diop, the gentleman thief who has captured the hearts of viewers in France and around the world.”

To understand the copycat, you have to remember where Part 3 left Assane. After stealing the Black Pearl, winning the public’s sympathy, faking his own death, and saving his estranged mother’s life, Assane concluded that the only way to guarantee a safe and quiet life for his wife, son, mother, and best friend was to sacrifice his own freedom entirely — and turned himself in to the police. It was the rare cliffhanger the show had never tried before: the master thief in a cell, by his own choice. Part 4 picks up four years later. Assane has served his sentence and is ready to start a new life alongside his family, with one promise anchoring the plan: a trip to visit their family in Senegal with his son, Raoul.

That plan detonates almost immediately. A mysterious announcement signed by “Lupin” claims responsibility for a wave of simultaneous heists at several museums — and the police begin hunting for “a new Lupin.” Assane proclaims his innocence, but the evidence against him is alarming: a camera appears to place him at a museum during a robbery, one in which Captain Sofia Belkacem is seriously injured. With the thefts going ahead despite heightened security, Assane is forced back into action to clear his name and confront whoever is impersonating him. The copycat premise is a clever inversion of the show’s founding engine — Assane spent three seasons using the legend of Arsène Lupin as cover for his crimes; now someone is using the legend of Assane as cover for theirs.

The returning ensemble is confirmed by both Deadline and Netflix’s Tudum: Ludivine Sagnier is back as Claire, Antoine Gouy as Benjamin Férel, Soufiane Guerrab as Youssef Guédira, and Shirine Boutella as Sofia Belkacem. Newcomers Théo Christine and Laïka Blanc-Francard join the company in undisclosed roles — the mystery around their characters is deliberate, with the marketing keeping their function in the copycat plot under wraps. Notably, Etan Simon, who played Assane and Claire’s son Raoul in the first three parts, does not appear among the announced returning cast — a conspicuous absence given how central the promise of the Senegal trip is to Assane’s motivation.

Behind the camera, the continuity is strong. Lupin was created by George Kay in collaboration with François Uzan, with the participation of Marie Roussin, Florent Meyer, and Tigran Rosine; Part 4 is written by Meyer, Rosine, Mathilde Arnaud, and Jean-Yves Arnaud, and directed by Edouard Salier, Everardo Gout, and Hugo Gélin for Gaumont, with the participation of Carrousel Studios. Sy, speaking with Netflix’s Tudum, described the show as an extraordinary plaything — a role he returns to with undiminished joy each time they make a new season. The official trailer arrived in mid-September on Netflix’s YouTube channel, and the “LUPIN RETURNS OCTOBER 23” announcement has been running across Netflix’s social accounts since.

The weight Part 4 carries is a direct result of what the series already did. Part 1 premiered on January 8, 2021, and was watched by 76 million households in its first month — at the time, the most-watched non-English series in Netflix history. Inspired by Maurice Leblanc’s classic Arsène Lupin character, the Paris-set show built its reputation on elaborate heists, sharp disguises, and a hero who always seems to stay several steps ahead of everyone chasing him. It debuted to critical acclaim, won a Critics’ Choice Award for Best Foreign Language Series, and earned nominations for Best Drama Series at the International Emmy Awards and the Golden Globes. Five years on, it remains one of the platform’s signature international originals — and one of the few shows where the Part naming convention feels like a mark of distinction rather than a hedge.

That history is what makes the copycat engine so promising. Lupin has always been a show about the gap between the legend and the man — Assane modeled himself on Leblanc’s fictional gentleman thief, borrowing the name’s mythic weight to pull off the impossible. Season 4 asks what happens when the legend detaches from the man entirely: someone out there is now doing to Assane what Assane did to Lupin. The trailers show Assane switching disguises and sowing confusion while insisting on his innocence, and the stakes are personal in a way the show’s heists haven’t been since Part 1: this time the people hunting him think they already know exactly who he is.

For American audiences, the October 23 drop continues a pattern: the series’ fall releases have become appointment binge-viewing, and Netflix is releasing all eight episodes simultaneously at midnight Pacific. All that remains is the question the copycat plot poses in the show’s own terms: after four years inside, is the greatest thief in Paris still the man — or is the name now bigger than he is?
