Steven Spielberg’s ‘Disclosure Day’: Plot, release date, cast, trailers and everything to know about Emily Blunt’s sci-fi thriller

Legendary filmmaker Steven Spielberg is returning to the sci-fi genre with his highly anticipated film ‘Disclosure Day’, and the buzz around the movie is already sky-high. Featuring Emily Blunt in the lead role alongside Josh O’Connor and Colin Firth, the upcoming alien thriller is set to release in theatres and IMAX on June 12, 2026.

Even before its release, the film has sparked massive curiosity online, thanks to its mysterious trailers, eerie visuals, and Spielberg’s return to extraterrestrial storytelling nearly two decades after ‘War of the Worlds’.

What is ‘Disclosure Day’ about?
While the makers have kept most plot details under wraps, ‘Disclosure Day’ revolves around humanity discovering the shocking truth that humans may not be alone in the universe.


The official description reads: “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 story reportedly follows a Kansas City TV meteorologist who appears to be controlled by an extraterrestrial force during a live television broadcast, triggering panic and global revelations about alien existence.


The trailers hint at UFO sightings, government secrecy, crop circles, strange animal behaviour, and a possible extraterrestrial invasion. Several scenes also suggest psychological manipulation, body-swapping, and large-scale chaos unfolding across the world.

‘Disclosure Day’ cast
The film stars Emily Blunt in the lead role, continuing her streak of sci-fi performances after films like ‘Edge of Tomorrow’ and ‘A Quiet Place’.

The cast also includes:

* Josh O’Connor
* Colin Firth
* Colman Domingo
* Eve Hewson

However, the makers have not yet revealed detailed character descriptions.

‘Disclosure Day’ trailers create online frenzy
Two trailers for the film have already been released. The first teaser arrived in December 2025, while the second trailer premiered during Super Bowl LX in February 2026.

The footage showcased mysterious crop circles, giant flying saucers emerging from clouds, intense car chases, strange broadcasts, and unsettling paranormal imagery.

One of the trailer’s most talked-about lines says: “There will be no other day like tomorrow.”

Who is directing ‘Disclosure Day’?
The film is directed by Steven Spielberg and is based on his original story idea. The screenplay has been written by David Koepp, who previously collaborated with Spielberg on iconic films like ‘Jurassic Park’ and ‘War of the Worlds’.

The project is backed by Amblin Entertainment, with cinematography by Janusz Kaminski and music composed by legendary composer John Williams.

Spielberg’s long-standing fascination with extraterrestrial life has shaped some of Hollywood’s biggest sci-fi classics, including ‘E.T.’ and ‘Close Encounters of the Third Kind’. ‘Disclosure Day’ now marks his major return to alien-based storytelling after nearly 20 years.
