Lupin Part 4: Where to Watch, Full Cast and the Copycat Mystery

A man is in prison. Museum robberies take place outside it. Then a recording appears to put that same man at the scene. Lupin Part 4 begins with a contradiction that strikes at Assane Diop’s greatest advantage: his ability to control what other people see. This time, someone else is shaping the picture. All eight episodes arrived on Netflix on October 23, 2026, so the fourth part is available now rather than awaiting a future release.

Netflix’s official premise places the story four years after the previous installment. Assane wants to complete his sentence and reunite with his family, including a promised journey to Senegal with his son. An announcement bearing the Lupin name interrupts that plan. Several museums are targeted at once, the robberies succeed despite security preparations, and material from one of the crimes appears to implicate him. Police captain Sofia Belkacem is seriously injured. Assane must identify the person exploiting his reputation while confronting the consequences for people around him.

That is the announced setup, not a solution to the mystery. The trailer offers a useful introduction to its tone and central problem, but a trailer is edited promotional material. It should not be treated as a complete map of the episodes or as proof that an apparent confrontation ends in a particular way. This guide leaves the impostor’s identity, the mechanics of the later schemes and the conclusion for viewers to discover.

The premise changes the meaning of recognition. In an ordinary pursuit, an identifiable face helps police connect a person to an action. In a story built around disguise and impersonation, the viewer has to ask what the image actually establishes. Seeing Assane is no longer the end of the question. It is the beginning of a problem about access, opportunity and who benefits from making him visible. That is an interpretation of the published premise, rather than a claim about an unrevealed episode.

The family promise gives the puzzle a second measure of success. Clearing a name and keeping a commitment are different tasks. A character might complete a brilliant escape while making the people waiting for him feel abandoned again. The time jump makes that tension particularly direct: four years can be a period someone intends to put behind him, but it can also be a substantial part of another person’s childhood.

New viewers should start with Part 1. Lupin follows Assane, a contemporary character inspired by Maurice Leblanc’s gentleman thief, rather than simply staging the original literary character’s adventures in order. Earlier parts establish the family relationships, recurring police figures and the significance of the Pellegrini name. Returning viewers who remember the broad outline can use Netflix’s official recaps before opening Part 4. Choose a recap labeled for the earlier parts; an ending explainer for the new installment answers a different question and reveals its conclusion.

Omar Sy returns as Assane Diop. Around him, the cast divides into people who know the man, people who know his methods and people affected by the distance between the two. That is a useful way to approach the ensemble without reducing it to a row of names. A disguise may persuade a stranger; it has a different effect on a friend who recognizes the habit behind it or a relative who has already lived with its consequences.

Ludivine Sagnier plays Claire Laurent, Assane’s longtime partner and Raoul’s mother. Antoine Gouy returns as Benjamin Férel, the trusted friend whose antiques knowledge and practical assistance are integral to Assane’s operations. Soufiane Guerrab plays Youssef Guédira, the detective whose familiarity with the Lupin books gives him a distinctive understanding of the thief. Shirine Boutella returns as Sofia Belkacem, now a police captain. Clotilde Hesme appears as Juliette Pellegrini, whose family history remains connected with Assane’s.

The most immediately noticeable casting change concerns Raoul. Théo Christine takes over the role previously played by Etan Simon in Parts 1–3. The change accompanies the four-year movement in the story, with Raoul approaching adulthood. It is a recast of an established character, not a second son or a separate person with the same name. Netflix also identifies Laïka Blanc-Francard as newcomer Adèle. This guide names the role without explaining how her place in the mystery develops. The canine performer Monette returns as J’Accuse.

For viewers checking the credits, the distinction between performer and character matters. Searching for “Théo Christine Lupin” answers who plays Raoul now. Looking for Etan Simon explains the earlier portrayal. Both names can legitimately appear in material about the series, but an older cast listing does not establish the fourth part’s role assignment. Netflix’s dated Part 4 cast guide is the more specific source for that change.

The ensemble also explains why Lupin is more than a sequence of ingenious thefts. A partner in a scheme can help solve a technical difficulty. A family member can ask whether solving it is worth the absence it creates. An investigator can understand the same literary reference as the suspect and still have duties that prevent an easy alliance. Those relationships give readers useful points of attention before watching, without telling them which character will act in which way.

The names behind the production supply another connection across installments. Netflix credits George Kay as creator, working with François Uzan and with participation from Marie Roussin, Florent Meyer and Tigran Rosine. Omar Sy and Louis Leterrier are the showrunners; Gaumont produces with Carrousel Studios. These credits identify the creative framework. They do not make a promotional announcement an independent review of the finished episodes. The cast and production information here comes from official records, while the viewing suggestions are editorial guidance.

Watch Lupin Part 4 through Netflix. The direct series page is netflix.com/title/80994082, where the service lists four parts and provides the official Part 4 trailer. Netflix’s release announcement confirms that the eight new episodes were released together on October 23. You do not need to wait for a weekly premiere schedule to reach the end of the installment. A Netflix membership and access through the service’s supported website or app are required for the episodes; the public trailer is promotional viewing.

Open the series, check the part selector and choose Part 4 before starting. This is worth doing even when a search result takes you directly to the right title. A general series page can display an earlier installment’s chapter descriptions by default. The presence of Part 1 descriptions on that page does not turn a confirmed fourth-part release into an unreleased season. The selector and the episodes presented in your signed-in account give the practical answer.

For viewers deciding how to listen, French is the original language. Netflix’s title page also lists dubbed audio and subtitle choices, while its Help Center explains that the options shown can depend on location, profile preferences, the title and the playback device. Check Audio & Subtitles after opening an episode. The language used by the app’s menus is a separate preference from the language of the performance. A French soundtrack with English subtitles and an English dub are different viewing choices, and either may suit a particular viewer’s needs.

If an expected language is missing, inspect the profile’s audio and subtitle preferences and then check the episode’s available tracks. Netflix advises that downloaded versions can display only the most relevant language options. That means the choices shown on an offline copy may be narrower than those shown when streaming. Before a trip, select the episode, confirm the language you want and test the downloaded copy rather than discovering the limitation after losing a connection.

The public Lupin page identifies the series as available to download. The download icon beside the specific episode in a supported Netflix mobile app remains the useful check for your account and device. Netflix’s download guidance covers supported phones, tablets and Chromebooks, and explains that downloads have expiry rules. They remain within the app; downloading is not a way to obtain a transferable video file. This guide does not promise that every device or subscription has identical download capacity.

No universal subscription price is quoted here because plans and prices depend on the market and can change. Likewise, a public Netflix listing is not a test of playback in every territory. Use the official title page from your own account to confirm local access and available tracks. The companion official trailer can help you decide whether the copycat premise appeals to you before committing to eight episodes. Once you begin, the central question is clear: can Assane regain control of his identity without losing the family future he meant to protect?
