'Disclosure Day': Plot, Release Date & Everything We Know About Steven Spielberg Movie

Steven Spielberg is a director whose name has guaranteed spectacular performances for decades. From Jaws to Jurassic Park to Saving Private Ryan to E.T., he knows how to make films that become events.

His new project, Disclosure Day, promises to be the biggest sci-fi premiere of 2026. It appears that Spielberg is returning to the topic of contact with extraterrestrial intelligence, but from a completely unexpected angle.

Here's what we know so far about Disclosure Day.

'Disclosure Day' Release Date & Trailer

The premiere of Disclosure Day was originally scheduled for May 15, 2026, but the studio pushed back the release date. The movie will now be released worldwide on June 12, 2026.

The first trailer of Disclosure Day was released in December 2025.

What Will 'Disclosure Day' Be About?

Although plot details are being kept under wraps, we know that the movie centers on the moment when humanity suddenly realizes that it is not alone in the universe. Spielberg is more interested in people's reactions to this revelation than in the aliens themselves.

How will society react when this fundamental illusion collapses? In the trailer, a Kansas City news anchor, played by Emily Blunt, attempts to read aloud, but her voice is replaced by alien clicking sounds.

Colin Firth plays an enigmatic character who controls a command center, while Josh O'Connor plays a character who insists that people have a right to know the truth.

Disclosure Day will apparently balance psychological drama, science fiction, and conspiracy thriller elements.

Fans' Theories About 'Disclosure Day' Plot

Of course, the internet couldn't ignore such a mysterious trailer. The most popular theory revolves around numbers. The synopsis states that seven billion people will discover the truth, even though Earth's population has surpassed eight billion.

Fans have speculated that the remaining billion-plus people are aliens living among us.

Another hypothesis concerns animals – the trailer pays an unusually large amount of attention to them. Perhaps the aliens aren't humanoids from another planet but rather nonhuman intelligences observing us through birds and animals.

The poster featuring Emily Blunt against a transparent bird silhouette only strengthens this theory.

Who Is in the Cast of 'Disclosure Day'?

Emily Blunt plays a weather presenter, while Josh O'Connor apparently plays a crusader for truth. Colin Firth plays the head of the mysterious command center, and judging by the stills, his aristocratic image takes on a sinister edge.

The cast also includes Colman Domingo, Eve Hewson, and Elizabeth Marvel.

Character names and details about their roles are not yet being revealed, but the cast itself suggests that Spielberg is assembling a top-notch ensemble.
