All we know about Steven Spielberg's new movie as first trailer drops

The highly anticipated trailer for Steven Spielberg's upcoming alien movie has finally dropped.

The sci-fi boasts a star-studded cast and marks Spielberg's return to the genre.

Up until Tuesday (December 16), little was known about the new film, with a few cryptic clues dropped here and there.

Even with the release of a two-minute long trailer, details surrounding the release still remain rather vague.

That's to say; the trailer doesn't give away every single plot detail.

Due for release in 2026, it's Spielberg's first release since 2022 drama The Fabelmans.

His previous alien movies include 1977's Close Encounters of the Third Kind, E.T. the Extra-Terrestrial in 1982 and 2005's War of the Worlds.

The new film - called Disclosure Day - stars Emily Blunt, who previously led the cast in 2016's The Girl on the Train, and is produced by Spielberg's production company Amblin Entertainment.

Here's everything we know now the trailer has finally released.

What is Disclosure Day about?

The movie appears to be about an alien universe being 'disclosed' to the world.

Its teaser opens with the ominous question: "If you found out we weren't alone, if someone showed you, proved it to you, would that frighten you?"

It then shows Blunt as a Kansas City weather woman, who begins stuttering, choking and making strange clicking noises as she begins her live broadcast.

The teaser also shows Josh O'Connor's character insisting that 'people deserve to know the truth', revealing his intention to orchestrate 'complete disclosure, for the entire world, all at once'.

He later stands in what looks like a crop circle, reinforcing the film’s extraterrestrial undertones.

Another scene hears Blunt scream in fear that 'they're coming', as armed police storm the city.

Later on, a moose and a bird enter a young girls' bedroom. Blunt is seen walking with them into a house in a dream-like sequence.

Another character asks: "Why would he make such a vast universe yet save it only for us?"

Very, very cryptic indeed.

No official plot summary for Disclosure Day has been provided, but the studio is calling it simply a 'new original event film'. It is classed as a thriller.

Who is in Disclosure Day?

Oppenheimer's Blunt and Challengers' Josh O'Connor are joined by Kingsman's Colin Firth, Bad Sister's Eve Hewson and Rustin's Colman Domingo.

Wyatt Russell, Elizabeth Marvel, Henry Lloyd-Hughes and Michael Gaston are also reportedly cast in the movie, as per IMDb.

So too are Mckenna Bridger, Elliot Villar, Tommy Martinez, Patricia Connolly and Noah Robbins.

Chavo Guerrero Jr, Brian Cage and Gabby Beans also feature.

What had been teased previously?

A few sneaky hints had been shared leading up to the trailer's release.

One of those was the movie's release date, which was plastered on billboards in Los Angeles and New York City last week.

The posters featured an upside-down eye in the silhouette of a perched Northern cardinal bird.

In the black surrounding the captivating image was Spielberg's name and the words: "ALL WILL BE DISCLOSED 06.12.2026."

This led people to believe the movie would be titled 'Disclosure'.

What else do we know about the movie?
