Steven Spielberg’s Disclosure Day—a UFO conspiracy thriller starring Emily Blunt as a Kansas City meteorologist and former journalist—has drawn overwhelmingly positive first reactions, with several critics calling it the director’s best work in two decades. The film, Spielberg’s 37th as director, is set for release on June 12, 2025, and follows Blunt’s character, Margaret Fairchild, as she unravels a government cover-up about alien life . according to early social-media reviews from outlets such as Collider and Rotten Tomatoes, the performance of Blunt and the film’s emotional weight are generating particular praise.

Emily Blunt’s Performance Shines in Spielberg’s 37th Feature

Collider’s Editor-in-Chief, Steven Weintraub, described Blunt as “incredible” and urged audiences to see the film knowing as little as possible. Rotten Tomatoes’ reviewer called Disclosure Day “absolutely phenomenal,” adding that they were “hanging onto every word.” Film reporter Bill Bria echoed those sentiments, calling Blunt’s performance “accomplished” and the movie “riveting, moving stuff.” The film also stars Josh O’Connor, Colin Firth, Eve Hewson, and Colman Domingo in a screenplay by David Koepp, Spielberg’s collaborator on Jurassic Park and War of the Worlds.

From Firelight to Disclosure Day: Spielberg’s Lifelong UFO Obsession

The source report notes that Spielberg’s fascination with UFOs began in childhood, when his father woke him to watch the Perseid meteor shower near their New Jersey home. That wonder led to his first amateur sci-fi feature, Firelight (1964), which he screened at a local Phoenix theater. Disclosure Day marks a return to that early interest, echoing themes from Close Encounters of the Third Kind and E.T. The film is based on an original story by Spielberg, making it a personal project—one that, as he reportedly stated, asks: “If you found out we weren’t alone, if someone showed you, proved it to you, would that frighten you?”

Critical Consensus: Collider and Rotten Tomatoes Lead the Cheers

As reported by the source, first reactions have been almost uniformly positive. collider’s Weintraub wrote: “In a shock to absolutely no one, Steven Spielberg has delivered another towering home run with Disclosure Day.” Rotten Tomatoes branded the film “absolutely phenomenal,” while of the performance they added: “The score perfectly elevates every single scene. Part mystery, part Twilight Zone, something new entirely… WOW.” The source also states that production took place from February to May 2025 in New York, New Jersey, and Atlanta, with filming first reported in April 2024. The secrecy around the plot appears to be a deliberate marketing strategy, though the tagline promises that “the truth belongs to seven billion people.”

The Big Unanswered: What Lies Beneath the Government Cover-Up?

Despite the effusive early praise, the source leaves several questions open. The film’s central conspiracy is deliberately vague—the synopsis offers only a hypothetical about encountering proof of alien life. It remains unclear whether Disclosure Day will deliver a resolution equal to its build-up, or whether the performances alone can sustain the film beyond opening weekend. The source reports only critic reactions, not general audience sentiment, and no box-office projections are mentioned. Additionally, the extent of Spielberg’s directorial involvement beyond the original story and Koepp’s screenplay is undisclosed. These unknowns make Disclosure Day as much a guessing game as the plot it conceals.
