Rebecca Hall has been cast in a psychological thriller for Maison Margiela, except there is no movie to watch after the trailer ends. Released Wednesday, 9 September, Anonymity is the fashion house's autumn/winter 2026 campaign, starring Hall as an actress repeatedly confronted by a masked version of herself. Maison Margiela describes the project plainly as a 'trailer of a thriller film that does not exist'.
Directed and photographed by Thibaut Grevet, the campaign turns the collection into the wardrobe for an unfinished mystery about identity and doubling. Hall, whose film credits include The Prestige, Vicky Cristina Barcelona and The Night House, said she was drawn to how the project borrowed from the language of cinema.
Rebecca Hall Comes Face-To-Face With Herself
In Anonymity, Hall plays an actress preparing for a role when a masked double begins appearing around her, blurring the boundary between rehearsal and whatever is happening beyond it. The house frames their encounters around two questions: 'But who is real? How can we truly know ourselves?'
The double wears masks drawn from Maison Margiela's Artisanal work, turning the house's long-running interest in anonymity into the campaign's central plot device. Instead of explaining who the figure is or why she is following Hall, the trailer leaves those questions unresolved, borrowing the structure of a film preview designed to suggest a larger story without revealing it.
Hall said the cinematic references were part of the appeal. 'I liked that it was bold and original but also referential to cinema,' she said, adding that she recognised influences from filmmakers Dario Argento, Brian De Palma and David Lynch. Those references are reflected in the campaign's use of doubling, fragmented encounters and an increasingly uncertain sense of what Hall's character is seeing. Rather than presenting the clothes through a traditional campaign narrative, Anonymity uses the conventions of psychological thrillers to make Hall's shifting identity part of the collection's presentation, with the garments and masks functioning as elements of the fictional story rather than simply appearing as looks between scenes.
The Mask Is More Than a Costume
The masked double also links directly to Maison Margiela's autumn/winter 2026 collection, which brought its ready-to-wear and Artisanal lines together for a show in Shanghai. The house identifies Artisanal, Anonymity, Tabi and Bianchetto as four of its foundational codes. Under creative director Glenn Martens, who has led Maison Margiela since 2025, masks remain part of that established design language.
Several pieces featured in the campaign come directly from the collection. Maison Margiela highlights Second Skin material fused over an Edwardian tailcoat and skirt, tapestry covering a shift dress and its Bianchetto treatment on a long plunging dress. The Artisanal masks, meanwhile, become Hall's anonymous counterpart rather than functioning solely as runway styling.
A Fashion Campaign Disguised as a Movie
The format gives Hall an unusual role that also overlaps with themes she has explored behind the camera. Her 2021 adaptation of Nella Larsen's Passing, starring Tessa Thompson and Ruth Negga, marked her feature directorial debut and examined identity, perception and the ways people construct versions of themselves. In Anonymity, those questions are filtered through Maison Margiela's visual codes and the fictional actress Hall plays.
Maison Margiela's campaign never promises an answer to its mystery because the trailer is the entire project. The house's official description says Hall's encounters with her double 'question what is real', while its social campaign asks viewers, 'Who are you?' There is no release date, feature film or ending still to come: the unfinished thriller is the autumn/winter 2026 campaign itself.
