Steven Spielberg is returning to the world of science fiction with Disclosure Day, and the film’s first teaser trailer has officially arrived.

Set to hit theaters on June 12, 2026, Disclosure Day positions itself as a global-scale event movie centered on humanity’s oldest and most terrifying question: Are we truly alone?

Universal teases the premise with an unsettling message:

“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.”

The film boasts a stacked cast led by Emily Blunt (Oppenheimer, A Quiet Place), Josh O’Connor (Challengers, The Crown), Colin Firth (The King’s Speech, Kingsman), Eve Hewson (Bad Sisters), and Colman Domingo (Sing Sing, Rustin).

Disclosure Day is based on an original story by Spielberg himself, with a screenplay penned by longtime collaborator David Koepp, whose previous work with the director includes Jurassic Park, The Lost World: Jurassic Park, War of the Worlds, and Indiana Jones and the Kingdom of the Crystal Skull.

The film is produced by Kristie Macosko Krieger (The Fabelmans, West Side Story) and Steven Spielberg under the Amblin Entertainment banner, with Adam Somner and Chris Brigham serving as executive producers.

Spielberg’s legacy with extraterrestrial storytelling is unmatched. From Close Encounters of the Third Kind (1977) and E.T. the Extra-Terrestrial (1982) to his chilling 2005 adaptation of War of the Worlds, few filmmakers have shaped cinematic alien mythology as profoundly.

More recently, Amblin expanded into real-world phenomena with Netflix’s 2023 docuseries Encounters, which explores alleged true stories of human contact with unexplained and otherworldly events.

With Disclosure Day, Spielberg appears ready to once again blur the line between wonder and dread — and ask what happens when the truth is finally revealed to everyone.
