With Sudden, Ryusuke Hamaguchi returns to Cannes with a film shaped by silences, encounters and minimal decisions, where what truly matters unfolds in what his characters have not yet learned to say.
There are filmmakers whose style is immediately recognisable through a single image. Others through the rhythm of a conversation. Ryusuke Hamaguchi belongs to the second category. In his cinema, words never function as mere dialogue: they are spaces where people attempt to approach what they still do not fully understand about themselves. From Drive My Car to Wheel of Fortune and Fantasy and Evil Does Not Exist, the Japanese director has turned everyday conversation into a deeply cinematic form of emotional tension.
With Sudden, presented in the Official Competition of the 2026 Cannes Film Festival, Hamaguchi returns precisely to that intimate and ambiguous territory where lives quietly shift direction without the characters ever quite realising the exact moment it happens.
And perhaps that is why the film left such a strange impression on the Croisette.
Not one of immediate impact.
But of gradual resonance.
Like conversations that return hours later, when one has already left the room.
The story follows Keiko, a Tokyo-based literary translator played by Sakura Ando, whose emotionally suspended routine begins to shift after she unexpectedly reunites with a former university acquaintance during an unanticipated storm. From that minimal — almost accidental — encounter, the film unfolds a series of conversations, urban journeys and seemingly small decisions that gradually reveal far deeper emotional fractures.
But describing the plot of Sudden is almost beside the point.
Because Hamaguchi does not truly work from narrative action. His cinema operates according to a different logic: the slow accumulation of contradictory emotions that emerge between words, silences and uncomfortable pauses. What matters is not what objectively happens. What matters is how conversations progressively alter the way characters perceive their own lives.
And in Sudden, that sensibility reaches one of its most delicate and melancholic forms.
Visually, the film possesses a deceptive serenity. Tokyo is filmed through an almost quiet intimacy, far removed from any urban spectacle. Small cafés, rain-soaked train stations, modest apartments and damp streets construct a city that seems to mirror the characters’ inner states. Hamaguchi films urban movement as if each journey contained the possibility of an unexpected emotional deviation.
The rain — present throughout much of the film — functions less as an atmospheric device than as a mental state. Everything feels slightly suspended. Unstable. As if the characters were living inside a moment of transition they have not yet been able to fully name.
And Sakura Ando captures that tone with extraordinary precision.
Her Keiko conveys a deeply contemporary emotional fatigue. Not explicit sadness, nor visible despair. Something harder to define: the feeling of having carefully organised a functional life while an essential part of the self remains quietly stalled elsewhere. Ando builds the character through minimal emotional shifts — a broken breath, a gaze held too long, a silence in which she seems to be weighing all the lives she might have lived.
Opposite her, Masaki Okada brings an oddly warm yet evasive presence to the former university acquaintance whose return reopens emotional zones Keiko believed to be fully closed. Their conversations carry that unmistakable quality of Hamaguchi’s finest cinema: people speaking about ordinary matters while something far deeper and harder to articulate circulates beneath every sentence.
In Cannes, much of the post-premiere discussion revolved around this ability to transform minor encounters into emotionally devastating experiences without ever resorting to overt melodrama. Some critics described Sudden as a spiritual continuation of Wheel of Fortune and Fantasy, particularly in the way it observes small emotional accidents capable of altering an entire existence. Others pointed to a new melancholy in Hamaguchi’s cinema: a more explicit sense of generational exhaustion and the contemporary difficulty of building genuinely honest relationships.
And perhaps that is precisely where the film’s power lies.
Because Sudden seems to constantly speak about people who are emotionally displaced within perfectly functional lives. Characters who work, converse and maintain stable relationships while quietly experiencing a profound sense of inner disconnection.
Hamaguchi never dramatises this overtly.
He observes it.
With an almost documentary-like patience.
Entire scenes are built around conversations in which nothing extraordinary appears to happen. And yet, the viewer gradually perceives how characters begin to confront emotional truths they have avoided for years.
That handling of emotional time remains one of the defining singularities of Hamaguchi’s cinema. The film never accelerates for narrative impact. It allows silences to last. Conversations to breathe. Discomfort to remain within the scene long enough to become recognisable.
In a Cannes edition marked by films driven by political violence, social crises and large-scale historical fractures, Sudden operated from a far more intimate and quiet register. But precisely for that reason, it resonated deeply with many viewers.
Because Hamaguchi seems to understand something essential about the contemporary moment: most people no longer live through visible, large-scale tragedies. They live through accumulated small emotional displacements. The sensation of having slowly drifted away from themselves without remembering exactly when it happened.
And Sudden captures that state with extraordinary precision.
Even its title functions as a subtle emotional irony.
Nothing in the film truly happens abruptly.
Everything changes slowly.
Almost imperceptibly.
Until one day the characters realise their lives no longer fully resemble what they once imagined.
At Cannes, where media noise often rewards films designed for immediate impact, Hamaguchi’s new work lingered in a different way. Quieter. More intimate. Harder to summarise quickly.
Like certain essential emotions.
Or like those late-night conversations that seem insignificant until, much later, one understands that something began there that is still quietly changing everything.
