Spielberg Made His First-Ever CinemaCon Appearance to Debut New Footage From “Disclosure Day.” It Opens Eight Weeks Before the Real Documents Do.

On April 15, 2026 — one day after Rep. Anna Paulina Luna’s Pentagon deadline for 46 classified UAP videos quietly passed without confirmed compliance — Steven Spielberg walked onto the CinemaCon stage in Las Vegas for the first time in his 79-year career to promote a film called Disclosure Day. He had never appeared at CinemaCon before. The timing was not subtle. Rep. Luna posted that same afternoon that the Pentagon had failed to respond until her office followed up, and suggested the letter may not have reached the appropriate authorities. While Washington processed that, Las Vegas got new footage of Emily Blunt speaking in alien language on live television and Spielberg saying, with a straight face, that he made this film “with certainty that there is a lot more truth than fiction to what you’re going to see on June 12.”

Disclosure Day arrives in theaters and IMAX on June 12, 2026, from Universal Pictures and Amblin Entertainment, screenplay by David Koepp from a story by Spielberg. The cast includes Emily Blunt as a Kansas City meteorologist who begins speaking in an alien language mid-broadcast; Josh O’Connor as a whistleblowing cybersecurity expert; Colin Firth as the head of a corporation called Wardex; Eve Hewson as O’Connor’s girlfriend; and Colman Domingo as a Wardex defector who advocates for disclosure. The score is by John Williams — the thirtieth collaboration between Williams and Spielberg.

The logline, distributed since the first teaser in December 2025: “If you found out we weren’t alone, if someone showed you, proved it to you, would that frighten you? This summer, the truth belongs to seven billion people. We are coming close to… Disclosure Day.”

What Spielberg Said at CinemaCon

Spielberg at 79 appearing at CinemaCon for the first time is not nothing. The event is an annual convention of theater owners — the people whose buy-in determines how many screens a film opens on. The fact that Spielberg came himself, accepted an award, and showed new footage signals a level of personal investment and institutional promotion weight that the film’s positioning demands.

His remarks were calibrated carefully. When asked about his personal beliefs on UAP, he noted his 1977 film Close Encounters of the Third Kind was fifty years ago and said: “In 2017, I got very curious again” — a reference to the New York Times story that year about Navy pilot UAP encounters and the AATIP program. “Half a century later, I made Disclosure Day with certainty that there is a lot more truth than fiction to what you’re going to see on June 12.”

Earlier, at South by Southwest in March, he had said: “I don’t know any more than any of you do, but I have a very strong suspicion that we are not alone here on Earth right now — and I made a movie about that.”

The new CinemaCon footage confined itself to the film’s first act: a global outbreak of strange behavior beginning with Blunt’s weather reporter, who becomes possessed mid-broadcast, followed by government attempts to suppress her and the appearance of O’Connor’s truth-seeker character. Spielberg specifically urged the theater owners not to spoil the third act, saying the audience needs to arrive without knowing the ending, and summarized the experience needed to watch the film: “All you need to get from the beginning to the end is a seatbelt.”

The Convergence That Nobody Can Stop Talking About

Disclosure Day opens June 12. Trump confirmed this weekend that “very interesting documents” from the UAP file review will be released “very, very soon” — a timeline that, depending on what “very soon” means in practice, could place the first actual government UAP document releases in public view within weeks of the film’s opening. The FBI is conducting a formal review of eleven scientist deaths and disappearances. The Pentagon missed a congressional deadline for 46 specific classified UAP videos, and the task force is not accepting that miss as final.

A 79-year-old director who has made four films about alien contact says he has a strong suspicion we are not alone and made a summer blockbuster to say so. The week he made his first CinemaCon appearance was the same week the government formally acknowledged it is investigating whether its scientists are being killed for what they know.
