Paul Walter Hauser and Mckenna Grace Star in Period Romantic Comedy 'The Official Mistress,' Filming Across Europe in September 2026

A revisionist romantic comedy set in the gilded corridors of Versailles is heading into pre-production, and the combination of a rising star cast, a globe-spanning European shoot, and a buzzy Cannes market launch makes this one worth putting on your radar early. 'The Official Mistress' is scheduled to begin principal photography in September 2026, giving crew professionals ample time to track this one and position themselves for what looks to be a mid-to-large-scale period feature with serious international ambitions.

Matt Brown is writing and directing, which makes this a passion project in the truest sense. Brown is best known for writing and directing 'The Man Who Knew Infinity' (2015), the biographical drama starring Dev Patel and Jeremy Irons about the Indian mathematical genius Srinivasa Ramanujan. That film demonstrated Brown's comfort working with period material, international coproductions, and emotionally grounded stories told against grand historical backdrops. All of that experience maps directly onto 'The Official Mistress.' The film casts Paul Walter Hauser as King Louis XVI, a genuinely unexpected and exciting piece of casting. Hauser has been on a remarkable ascent through Hollywood, earning widespread critical praise for his work in 'I, Tonya,' Richard Jewell,' and his Emmy-winning turn in 'Black Bird' for Apple TV+. He brings an earthy, humanizing quality to larger-than-life figures, which makes the choice to cast him as one of history's most scrutinized monarchs feel inspired rather than obvious. Mckenna Grace plays Comtesse Madeleine de Vascone, the official mistress of the title. Grace, a remarkably versatile young actress known for 'Ghostbusters: Afterlife,' 'The Handmaid's Tale,' and 'Gifted,' continues to move toward leading-lady territory, and this role positions her front and center in a female-oriented period piece designed with her generation of audiences in mind. Louis Partridge, who broke out in 'Enola Holmes' and has since appeared in 'Pistol' and 'Challenger,' rounds out the central trio as Rene Rennault, a humble cook who becomes the King's official food taster and risks everything to protect his first love.

The producing team is a genuinely interesting assembly of companies bringing different strengths to the table. Brunson Green of Harbinger Pictures brings Oscar-level credentials, having produced 'The Help,' which earned Best Picture and Best Actress nominations. Green has a long track record with prestige period and female-driven material, making him a natural fit here. Laura Rister produces through Esme Grace, while Laura Bull brings ReadyMade Films into the mix. Matt Brown himself is also producing, which is common for writer-directors on independently financed features and typically signals that he has significant creative control. On the international sales side, North.Five.Six is launching world sales at the Cannes market, which is a meaningful signal about where this project sits commercially. A Cannes market launch suggests the producers are assembling territory-by-territory financing and distribution, the standard model for ambitious independent features with international scope. Executive producers Michael Rothstein, Samuel Hall, and Warren Goz round out the oversight structure, likely representing financing and distribution relationships that support the film's scale.

The September 2026 production start with a confirmed European shoot is the detail that will matter most to crew. While specific cities have not yet been announced, a French court period piece of this scale will almost certainly look at France itself, potentially including Paris and the Ile-de-France region where Versailles sits, as well as potentially Belgium, the Czech Republic, or other European locations with strong period infrastructure and competitive production incentives. The Czech Republic in particular, centered around Prague, has become a go-to destination for European-set period productions, with robust stage facilities, an experienced period-drama crew base, and attractive incentives. France itself offers the TRIP tax rebate for international productions, which covers a meaningful percentage of qualifying French spend and has lured numerous high-profile productions in recent years. As specific locations are confirmed ahead of the 2026 shoot, crew in France, Central Europe, and the UK should monitor this listing closely. Given the production's independent financing model and international structure, it will likely look to maximize local crew hires wherever it bases, as is standard practice for incentive-qualifying productions.

As a period romantic comedy, 'The Official Mistress' will carry the crew demands typical of any large-scale historical production. The art department will be central to the entire enterprise, tasked with recreating the opulence of Louis XVI's Versailles in ways that feel simultaneously authentic and heightened for comedic effect. Costume and hair and makeup departments will similarly be major operations. The tone Brown is targeting, described as a female-oriented blend of historical romance and irreverent comedy, suggests something in the vein of 'The Favourite' or 'Barry Lyndon' filtered through a more accessible, commercially minded sensibility. That tonal balance will put real demands on production design and costuming to straddle lushness and wit at the same time. Given the cast and the producing pedigree attached, this appears to be a union-level feature production, though specific labor agreements will depend on the countries where shooting ultimately takes place.

With principal photography still the better part of a year and a half away, this production is in the window where the most senior positions are beginning to take shape behind the scenes. Cinematographers, production designers, and other department heads of the caliber this project will attract are typically approached well in advance of a September start, meaning conversations are likely already beginning or will begin in earnest as 2025 progresses. If you are a crew professional with period feature experience and availability in late 2026, this is the time to get on the radar.
