Steven Spielberg’s ‘Disclosure Day’ Trailer Teases UFO Mystery and Global Revelation

When Steven Spielberg makes a film, it’s more than just another movie release — it’s an event. And when that film tackles one of humanity’s oldest mysteries — are we alone in the universe? — anticipation turns into fascination. On December 16, the first trailer for Spielberg’s upcoming feature Disclosure Day landed online and in theaters, giving audiences their first glimpse of what promises to be one of the most talked-about releases of 2026.

The trailer doesn’t just tease spectacle; it hints at emotional stakes and philosophical questions that have threaded through Spielberg’s best work. This is the director who thrilled and startled the world with Close Encounters of the Third Kind and made us believe in friendship across galaxies with E.T. the Extra-Terrestrial. Now, nearly five decades after those classics, Spielberg returns to the alien genre with a story that speaks to modern audiences on both a human and cosmic level.

Spielberg's latest original science-fiction film, Disclosure Day, will be released in theaters on June 12, 2026. It was written by Spielberg and longtime collaborator David Koepp, who is known for hits like Jurassic Park and War of the Worlds. The ensemble cast is star-studded: Emily Blunt leads as a TV anchor in Kansas City whose life takes an extraordinary turn, while Josh O’Connor portrays a character driven by an urgent conviction that the truth of alien existence deserves to be shared with all of humanity. Wyatt Russell, Eve Hewson, Colin Firth, and Colman Domingo are also on board, adding depth to a story that alternates between mystery, tension, and wonder. The trailer opens on familiar ground: ordinary life interrupted by the extraordinary. Blunt’s character, on live television, suddenly loses the power of speech in a way that is eerie and inexplicable, prompting the question that underpins the film: If definitive proof of extraterrestrial life were revealed, how would the world react?

That mysterious moment in the teaser — Blunt’s calm transition into strange, inhuman behavior — sets the tone for a story that seems poised to explore how society grapples with seismic revelations. O’Connor’s character says plainly in the trailer, “People have a right to know the truth. It belongs to seven billion people”—words that fuel both the narrative drive and the emotional core of the film.

Visually, the teaser leans into atmosphere more than spectacle. Unsettling behavior from seemingly normal people, cryptic imagery that suggests something much larger is at play, and a mysterious broadcast that captivates the nation are all indications of unusual phenomena. While the trailer doesn’t show flying saucers or dramatic alien reveals, it strongly implies that the world of Disclosure Day will challenge the characters’ understanding of reality and their place within the universe.

The title itself — Disclosure Day — evokes a moment of revelation, the breaking of silence, and a confrontation with truth. It’s a concept that resonates with contemporary cultural curiosity about unidentified aerial phenomena (UAPs) and the possibility that governments may possess hidden knowledge about life beyond Earth. In recent months, UFO documentaries and discussions on disclosure have gained mainstream traction, adding to the cultural backdrop against which Spielberg’s film arrives.

Also noteworthy is Spielberg's return to science fiction as a creative homecoming. Since The Fabelmans in 2022 — a semi-autobiographical film that earned seven Oscar nominations — Spielberg hadn’t directed a feature rooted in speculative wonder. Disclosure Day reunites him with composer John Williams for what could be their 30th collaboration, further elevating anticipation for the movie’s score and emotional resonance.

While the first trailer carefully holds back its deepest secrets, it promises that Disclosure Day won’t just be about extraterrestrial contact. It is a tale about how humanity responds to change—how truth alters identity, belief, and the bonds that unite us. This grounding in character and human connection is classic Spielberg: the thrill of discovery, yes, but also the tender, bewildered heart of an ordinary person trying to make sense of the extraordinary.

As the film gears up for a summer 2026 release alongside blockbusters like Toy Story 5 and Supergirl, audiences are left with a question as old as science fiction itself: What would happen if the truth really were revealed? If the trailer is any indication, Disclosure Day might not just ask that question — it might make us feel the answer.
