Ryusuke Hamaguchi arrived at the 2026 Cannes Film Festival with a film that asked the international cinema business to accept several forms of friction at once. Soudain, also known as All of a Sudden, runs for three hours and sixteen minutes. It was made across France, Japan, Germany and Belgium, partly shot in France and led by Belgian actor Virginie Efira and Japanese actor Tao Okamoto. The two performers shared Cannes’s best-actress prize. For Hamaguchi, the award confirmed that his exacting way of building performance can cross language and production systems. For the companies behind the film, it began the more difficult work of turning festival authority into a viable theatrical life.
The project is a useful test of how global prestige cinema is financed. No single national market naturally absorbs all of its risk. The film draws on Japanese authorship and a Japanese co-production base, French production and distribution infrastructure, German and Belgian partners, public-service capital and international sales. That patchwork is not unusual for ambitious independent films. What is unusual is the degree to which Hamaguchi’s name can hold the pieces together without forcing the work into a more conventional commercial shape.
His position has changed sharply since Drive My Car won the Academy Award for international feature and introduced a much larger audience to his extended running times, rehearsal-based process and controlled emotional tempo. Success did not turn Hamaguchi into a franchise director. It made his method an asset that financiers and distributors could recognise. Soudain shows how far that asset can travel. It is his first feature partly shot in France and his first built around a major French-language star, yet it remains visibly organised around the patient accumulation of behaviour rather than plot acceleration.
An auteur as financing infrastructure
International co-productions are often described as creative exchanges, but their foundation is financial. Partners assemble tax incentives, broadcasters, regional funds, distribution commitments and rights across territories. Every additional participant can widen the available capital while also increasing the number of approvals, delivery obligations and recoupment positions. A director with a strong festival record reduces uncertainty because selection at Cannes, Venice or Berlin can unlock sales and publicity before the film reaches cinemas.
Hamaguchi now performs that de-risking function. His name signals seriousness to festivals, cultural institutions and specialist distributors. It also signals a set of complications. His films do not promise a high number of daily theatrical screenings. They resist simplified marketing, and their emotional force is difficult to compress into a trailer. The commercial proposition is therefore not volume but distinction: a film that gives cinemas, distributors and streaming catalogues an event with long critical life.
Soudain was produced through a network that includes Cinefrance Studios, Japanese partners Office Shirous and Bitters End, Germany’s Heimatfilm and Belgium’s Tarantula, with Arte France Cinéma among the participating institutions. The resulting structure spreads exposure and roots the film in several release ecosystems. France has a strong theatrical culture and public support for cinema. Japan remains a substantial domestic market with sophisticated audiences for local film. Germany and Belgium add financing and production capacity. International sales and North American distribution extend the afterlife.
The arrangement also illustrates why Asian filmmakers with global reputations increasingly operate through European capital. Hollywood is capable of financing international directors, but usually wants English-language accessibility, compressed schedules or identifiable genre. Europe’s co-production system can tolerate slower returns when cultural value, broadcasting and theatrical policy share the burden. The trade-off is administrative complexity and a fragmented rights map.
The long film problem
Running time is not an abstract artistic question for exhibitors. A film lasting more than three hours occupies a screen long enough to reduce the number of sessions available in a day. It raises staffing and scheduling costs, narrows casual attendance and competes poorly with shorter releases for prime evening slots. Premium pricing can recover some of the difference, but specialist cinema audiences are price-sensitive and many independent venues have limited capacity.
Hamaguchi has already demonstrated that duration can become part of an event. Happy Hour extended beyond five hours; Drive My Car approached three. Viewers who commit to these films are not being surprised by length. They are buying into a rhythm. That expectation creates a brand, and a brand can support advance bookings, limited engagements and carefully programmed runs. It cannot erase the arithmetic of screen time.
This is why the release sequence matters. Cannes supplies concentrated attention and a prestigious award. France’s planned August theatrical opening gives distributors time to convert that attention into reviews, partnerships and audience education. Japan can market the film as the return of a major national director working on a wider canvas. A North American specialist distributor can use awards season and repertory relationships to stretch the campaign. Each territory has a different reason to believe the film will matter.
The risk is that prestige becomes a substitute for reach. A film can travel through festivals, collect strong reviews and appear in year-end lists while remaining inaccessible to most paying audiences. Streaming eventually broadens availability, but the economics and visibility of a late catalogue release are very different from those of a theatrical event. Hamaguchi’s commercial test is not to become a mass-market filmmaker. It is to demonstrate that patient work can generate enough concentrated demand to sustain the companies willing to finance it.
Performance as the exportable technology
The most valuable part of Hamaguchi’s practice may be the least visible to the market: his system for preparing actors. He is known for extended readings and a rehearsal process that separates command of text from expressive decisions. The approach can look austere, yet its business value is portability. It does not depend on a particular star system, genre or production scale. It can be applied to Japanese ensembles, non-professional performers or an international cast working across languages.
Efira and Okamoto’s shared Cannes prize is evidence that the method survived the move. It also gives distributors a stronger marketing proposition than authorship alone. Acting prizes attach faces and emotional stakes to a film that might otherwise be sold primarily on a director’s reputation. For co-producers, that recognition validates the risk of combining distinct working cultures.
Hamaguchi’s expansion differs from the common route in which an Asian director is recruited to execute an established Western franchise. He carried a production method outward rather than entering somebody else’s intellectual property. That preserves creative authority and gives the partners a film that could not easily have been produced by replacing him. Scarcity is central to the economics of auteur cinema. If the work becomes interchangeable, the reason to assemble a complex international package disappears.
The approach also has implications for Japan’s film industry. Japanese studios and distributors have deep domestic expertise, but global financing and marketing remain uneven. Hamaguchi’s partnerships show one path: keep a Japanese creative centre while using European structures to increase production flexibility and international access. The model will not suit every film. It depends on festival credibility that takes years to build and can be lost quickly.
What success must look like
Box-office expectations for Soudain should be measured against its financing model, not against a studio release. The meaningful indicators are territory sales, the length of theatrical runs, audience retention after the Cannes cycle and the film’s ability to support future projects. A modest gross spread across several markets can be more useful than a brief spike in one. Library value matters too: films by recognised auteurs continue to generate screenings, educational licences and platform demand long after their first release.
Yet the system is under pressure. Independent cinemas face higher costs; younger audiences have been trained to wait for streaming; global platforms can offer access without sharing detailed performance data. Public film funding remains politically exposed, especially when budgets tighten. Co-productions protect against some risks while creating vulnerability to changes in several countries at once.
Hamaguchi’s response has been to make the method, not the budget, the source of scale. Soudain is larger geographically and institutionally than much of his earlier work, but its value still rests on the precision of human interaction. That discipline keeps spending connected to the thing audiences and partners cannot obtain elsewhere.
The next twelve to twenty-four months will reveal whether the business surrounding him can match that precision. Cannes proved that a four-country production did not dilute his authorship, and the acting prize supplied a clear signal to the market. The remaining question is whether distributors can create a release strategy patient enough for the film but urgent enough for cinemas. Hamaguchi has shown that his Japanese method travels. Now the institutions that financed the journey must prove it can earn its way home.
That fragmentation can become an advantage when the release is carefully staged. Local partners understand exhibitors, press and public institutions in their own markets, while the film retains one creative identity across them. It can become a weakness when nobody has sufficient economic incentive to sustain the campaign after the premiere. Hamaguchi’s reputation attracts the coalition; the quality of coordination determines whether attention compounds or dissipates.
