Disclosure Day: Steven Spielberg's UFO Thriller Has Officially Unveiled Its Full Trailer — and the Internet Is Obsessing
Twenty years between alien films. That's how long Steven Spielberg made audiences wait before returning to extraterrestrial territory. Disclosure Day arrives June 12, 2026, in theaters and IMAX — and after the full official trailer dropped Thursday, it has become the most-discussed upcoming film of the summer in under 48 hours.
What Disclosure Day Is About
The premise is deceptively simple. The trailer opens with Josh O'Connor's character revealing he has stolen government secrets he was paid to protect. When he shares what he's taken with Eve Hewson's character, her first question is stark: "Are they people?"
O'Connor's character has access to long-held government files confirming the existence of beings not of Earth — the trailer flashes black-and-white footage hinting at Roswell, New Mexico. Emily Blunt plays a Kansas City meteorologist who begins inexplicably speaking in tongues on live television. O'Connor's character can understand what she's saying. The plan is full whistleblower disclosure — releasing the secrets to everyone — something Colin Firth's character is determined to stop.
Colman Domingo's character is heard stating: "This 79-year campaign of terror and lies has to end." Seventy-nine years before 2026 is 1947 — the year UFO reports first surfaced in New Mexico. The Roswell thread runs through the entire trailer.
The Disclosure Day Cast
Emily Blunt, Josh O'Connor, and Colin Firth lead the film, with Colman Domingo and Eve Hewson rounding out the principal cast. Wyatt Russell, Elizabeth Marvel, and Mckenna Bridger also appear. The production is pure Spielberg infrastructure: cinematography from longtime collaborator Janusz Kaminski, with a score composed by John Williams — his 30th collaboration with Spielberg.
David Koepp wrote the screenplay from Spielberg's original story. Koepp previously wrote Jurassic Park, War of the Worlds, and Indiana Jones and the Kingdom of the Crystal Skull with the director.
Where It Was Made and When
Filming ran from February to May 2025 across New York, New Jersey, and Atlanta. Universal Pictures distributes. The film opens June 12, 2026, in wide release and IMAX — timed, deliberately, to coincide with the 50th anniversary of Close Encounters of the Third Kind.
Trailer Reaction: Two Camps, One Film
Critical response to the trailer split fast. Den of Geek praised its unmistakable 1990s paranoia — comparing the mood directly to The X-Files and noting that O'Connor's government leaker and Blunt's alien-possessed newscaster carry the entire premise in under three minutes of footage.
Not everyone was sold. One prominent film critic called it a tired parody of itself, questioning the CGI quality and arguing practical effects had been abandoned. That reaction sits in the minority — the trailer has crossed 109,000 IMDB watchlist additions in under 72 hours.
The Spielberg Theory Driving Fan Speculation
The biggest fan theory circulating right now traces directly back to Spielberg himself. In a 2023 interview with Stephen Colbert, Spielberg laid out his personal belief that UAPs might not be visitors from distant galaxies but could be humans traveling back from 500,000 years in the future — returning as anthropologists to document a pivotal century. If Disclosure Day follows that logic, the aliens are not invaders but our own descendants.
A second teaser trailer was released during Super Bowl LX on February 8, 2026, and a full-length trailer arrived March 13. Both were cut to build mystery rather than answer it.
Disclosure Day opens in theaters and IMAX on June 12, 2026. Tickets go on sale closer to release at Fandango and theater box offices nationwide.
