‘Lupin’ star transforms beyond recognition in ‘Franklin’

Ludivine Sagnier appears in the 2024 Apple TV+ miniseries Franklin as Madame Brillon, an 18th-century musician whose powdered wigs and silk gowns make her nearly unrecognizable to viewers who know her as Claire Laurent in Lupin. The contrast has sent fans of the Netflix series searching for details on the Lupin cast member behind the transformation.

Role in Franklin

Sagnier plays the real-life Anne-Louise Brillon de Jouy, a composer who befriends Benjamin Franklin during his Paris mission for the American Revolution. The eight-episode series, directed by Tim Van Patten and starring Michael Douglas, premiered in April 2024 on Apple TV+.

Costume designer Christine Wada placed Sagnier in pannier skirts and lace caps that match period portraits rather than modern Parisian chic. Hair and makeup teams added graying ringlets and pale powder, completing the shift from the sleek, contemporary look of Claire Laurent.

Brillon’s scenes show a woman of wit and influence who hosts salons and plays the harpsichord, giving Sagnier a character arc centered on intellect and status instead of the domestic tension Claire experiences across Lupin Parts 1–4.

Claire Laurent in Lupin

In the Netflix series, Sagnier portrays Assane Diop’s estranged wife and mother of their son Raoul. Claire’s storyline spans four parts, including the four-year time jump in Part 4 released October 23, 2026.

Her wardrobe choices remain urban and understated, usually tailored coats and simple jewelry that signal a working professional navigating Paris. The visual language keeps Claire firmly grounded in the present day.

Claire’s emotional register focuses on co-parenting and lingering resentment toward Assane’s schemes, a register that feels distant from the powdered formality of Brillon’s aristocratic world.

Visual contrast

Side-by-side images circulating on social media highlight how Sagnier’s facial features are softened by period makeup and framed by curls that replace her usual straight bob. The difference has prompted comments that the two characters could pass as unrelated women.

Production stills from Franklin show Sagnier in candlelit interiors that flatten modern bone structure under heavy lighting and fabric. The same actress appears sharper in Lupin scenes shot in contemporary apartments and Metro stations.

Viewers who binge both projects in quick succession report needing a second glance before recognizing the shared performer, a reaction amplified by the rapid October 2026 release of Lupin Part 4.

Other Lupin cast members

Omar Sy remains the anchor of the Lupin cast as Assane Diop, appearing consistently across all parts without any period detour. His look and manner stay rooted in the present-day narrative.

Supporting players such as Soufiane Guerrab, Shirine Boutella, and newcomer Théo Christine, who recast Raoul for Part 4, have no documented roles in Franklin. Their recent work stays within the French thriller or contemporary drama lanes.

The absence of crossover appearances from the rest of the ensemble keeps Sagnier’s transformation the clearest example of range within the Lupin cast at the moment.

Period piece context

Franklin adapts Stacy Schiff’s book A Great Improvisation and follows the diplomat’s efforts to secure French support for the American Revolution. Sagnier’s Brillon adds a French perspective that complements Michael Douglas’s lead performance.

Apple TV+ positioned the miniseries as prestige historical drama, a category that rewards actors who can shift from contemporary roles into corseted restraint. Sagnier’s casting fits that brief without requiring a name change or accent shift.

The production filmed in Prague and Paris locations chosen to evoke 1770s architecture, allowing Sagnier to move between salons and gardens that have no visual overlap with Lupin’s urban settings.

Cultural reception

Early reviews noted Sagnier’s ability to convey Brillon’s intelligence and flirtation without leaning on the glamour associated with her Lupin character. Critics described the performance as restrained and precise.

French media outlets framed the role as another step in Sagnier’s move between arthouse cinema and global streaming, following earlier work in Swimming Pool and The Young Pope. U.S. coverage focused on the surprise of seeing a Lupin regular in powdered hair.

Social media threads tracking the Lupin cast often pair screenshots of Claire in jeans with Brillon in lace, turning the visual gap into lighthearted commentary on actor versatility.

Industry implications

Streaming platforms continue to cast French performers in English-language period projects, and Sagnier’s placement in Franklin reflects that trend. Her prior Netflix visibility makes the booking a low-risk choice for Apple TV+.

Agents and casting directors note that actors who can toggle between modern thrillers and historical drama remain in demand for limited series that rotate through different eras. Sagnier’s schedule now spans both categories.

The October 2026 release of Lupin Part 4 keeps her name attached to contemporary French television even as Franklin reruns circulate on Apple TV+, giving her simultaneous exposure in two distinct visual registers.

Upcoming projects

Sagnier has no announced follow-up period role, but her agents have fielded inquiries for additional 18th- and 19th-century projects. The Franklin credit functions as a calling card for that lane.

Meanwhile, the Lupin production team has signaled that Part 5 remains in development, keeping Sagnier’s Claire Laurent storyline active. The character’s arc after the four-year jump is still being mapped.

Any future season will likely maintain Claire’s modern aesthetic, preserving the contrast with Brillon and reinforcing the perception that Sagnier can toggle between centuries on short notice.

Takeaway

Ludivine Sagnier is the Lupin cast member whose appearance in Franklin demonstrates the clearest physical and tonal shift. The role expands her range at a moment when both Lupin Part 4 and Franklin reruns keep her visible to overlapping audiences, and it positions her for future historical projects without detaching her from the Netflix series that introduced her to many U.S. viewers.
