‘Disclosure Day’ Review: Emily Blunt and Josh O’Connor Shine in Spielberg’s Ambitious Sci-Fi Thriller

Steven Spielberg’s Disclosure Day asks a deceptively simple question: who gets to control the truth? The answer arrives through an ambitious science-fiction thriller centered on Daniel Kellner (Josh O’Connor), a cybersecurity expert who discovers evidence proving humanity is not alone. Pursued by Wardex, the powerful organization responsible for concealing decades of extraterrestrial contact, Daniel finds himself on the run while meteorologist Margaret Fairchild (Emily Blunt) begins experiencing strange abilities connected to the same mystery. As their paths converge, Spielberg crafts a blockbuster that is as interested in empathy, faith, and knowledge as it is in alien life itself.

From its opening moments, Disclosure Day establishes an immediate sense of intrigue. Daniel’s journey creates a compelling framework for a story that continually expands in scope, while Margaret’s experiences add another layer of uncertainty. Spielberg carefully layers questions atop one another, creating the impression that every revelation is only exposing a larger puzzle waiting beneath the surface. The result is a film that keeps audiences invested not because of what they know, but because of what they still don’t understand.

Spielberg transforms science fiction into an act of discovery. The film’s most memorable sequences aren’t built around destruction or spectacle, but around the thrill of understanding. Whether exploring the conflict between Wardex and The Collective or the film’s shifting realities, Spielberg repeatedly invites audiences to question what they’re seeing rather than simply observe it. The wonder comes from trying to understand the rules of the world rather than watching them explode. It is a refreshing approach that allows Disclosure Day to stand apart from many contemporary blockbusters.

The film’s exploration of truth proves equally compelling. Throughout the narrative, Spielberg examines the value of information and the dangers of allowing institutions to become its sole gatekeepers. The conflict between disclosure and secrecy evolves beyond a traditional struggle between opposing sides, becoming a debate about responsibility, faith, and whether humanity is prepared to confront a reality that would fundamentally alter its understanding of itself. Rather than offering easy answers, the film leaves room for discussion, encouraging audiences to wrestle with its ideas long after the credits roll.

Yet Disclosure Day‘s most powerful concept is empathy. Through Margaret’s ability to experience the memories, emotions, and perspectives of others, Spielberg visualizes understanding itself. These sequences transform empathy into a cinematic language, reinforcing the film’s belief that truth alone isn’t enough. Knowledge without understanding is incomplete. If humanity is going to move forward, the film suggests, it must first learn how to see the world through someone else’s eyes. This idea elevates Disclosure Day beyond a conventional science-fiction thriller and gives its larger mysteries genuine emotional weight.

Emily Blunt delivers one of the finest performances of her career. As Margaret, she becomes both the emotional and philosophical center of the film, embodying its central themes with remarkable vulnerability and precision. The role requires her to carry not only her own emotional journey but fragments of countless others, and Blunt rises to the challenge with extraordinary depth. If Disclosure Day ultimately argues that understanding one another is humanity’s greatest strength, Blunt becomes the living embodiment of that idea. Her accent occasionally wavers, but it is a minor distraction within what is otherwise an exceptional performance.

Josh O’Connor delivers a quietly compelling performance as Daniel. Much of the film rests on his shoulders, and he rises to the occasion with a sincerity that grounds the increasingly ambitious narrative. Daniel spends much of the story reacting to revelations, evading capture, and questioning everything he thought he knew, yet O’Connor never loses sight of the character’s humanity. He provides the emotional anchor that allows audiences to remain invested even as the story expands into larger existential territory.

The supporting ensemble is equally strong. Colin Firth brings welcome complexity to Noah, refusing to portray him as a conventional villain. Instead, he leans into the character’s conviction that some truths may be too dangerous to reveal, giving the central conflict greater thematic weight. Colman Domingo provides the film with its moral backbone, grounding its larger questions in something recognizably human. Eve Hewson is captivating as Jane, bringing conviction and vulnerability to a character who feels essential throughout much of the first half. Unfortunately, the screenplay gradually sidelines her during the very stretch of the narrative where her perspective feels most important. It is less a failure of performance than one of narrative emphasis, leaving audiences wanting considerably more from one of the film’s most intriguing characters.

That imbalance extends to parts of the screenplay itself. While Disclosure Day excels as a mystery and thematic exploration, it is less successful as a chase thriller. The pacing that proves so effective early on becomes increasingly uneven as the narrative progresses, and several moments within the cat-and-mouse pursuit strain credibility. Daniel frequently manages to evade Wardex despite often appearing to be hidden in plain sight, undercutting the tension the film works so carefully to establish.

Even so, Disclosure Day never loses the sense of wonder that has defined Spielberg’s best work. Amid conspiracies, surveillance, and existential revelations, the film remains fascinated by the unknown. Spielberg approaches discovery with awe rather than fear, reminding audiences that curiosity itself can be thrilling. Whether exploring impossible phenomena or challenging humanity’s understanding of reality, he consistently returns to the same belief that has fueled much of his career: that there is value in asking questions, even when the answers remain uncertain. Disclosure Day may occasionally stumble in its execution, but its empathy, curiosity, and commitment to wonder make it one of the year’s most engaging science-fiction experiences.
