Anytime Steven Spielberg releases a new movie, it's a reason for excitement and celebration. When Disclosure Day hit the 2026 movie schedule, it led to exactly that. Over the decades, Spielberg has given audiences some of the most unforgettable alien movies (on top of some must-watch sci-fi flicks), and he'll be adding to that canon in just a few short weeks.
Many of us here at CinemaBlend have been obsessing over it for the past couple of years, and now it’s almost here. That said, come along with us if you want to learn everything we know about Disclosure Day, including its release date, cast, and a breakdown of that epic trailer that has had everyone talking for a while now.
What Is The Disclosure Day Release Date?
Disclosure Day is June 12, 2026. That is the day the movie will be released in theaters, and that comes in the middle of a crowded June.
The film is sandwiched between Masters of the Universe, the weekend before, and the double-whammy that is Toy Story 5 and Supergirl the following weekend. There’s going to be a lot of competition come June, and that’s just a precursor of what’s to come in July, when the upcoming Spider-Man: Brand New Day, Christopher Nolan’s The Odyssey, and several others hit the big screen.
Still, this is Speilberg were talking about, so even though it's not based on an existing IP like many of the summer blockbusters, we have all the confidence that it'll will be one of the most popular movies of the season.
The Disclosure Day Cast
Over the years, Steven Spielberg has worked with some of the biggest names in Hollywood (we’re talking multiple generations), and he’ll add even more names to that long list when his latest big-screen adventure comes out there. That said, here’s a quick breakdown of everyone confirmed to be a part of the Disclosure Day cast:
- Emily Blunt as meteorologist Margaret Fairchild
- Josh O’Connor as Daniel Kellner
- Colin Firth as Noah Scanlon
- Colman Domingo as Hugo Wakefield
- Eve Hewson Jane Blankenship
- Wyatt Russell
- Elizabeth Marvel
- Henry Lloyd-Hughes
- Michael Gaston
- Elliot Villar as Agent Diaz
- Mckenna Bridger
- Gabby Beans
On top of all these actors, PW Insider reported in early 2025 that AEW wrestlers Brian Cage and Lance Archer would be appearing in a wrestling scene, as would the legendary Chavo Guerrero Jr., who is set to play a referee in a match. This makes it sound like we can add Disclosure Day to the list of movies with random wrestling scenes.
The Disclosure Day Trailer
After going the better part of a couple of years not knowing what the movie was going to be called (or be about), Universal Pictures finally released the Disclosure Day teaser in December 2025. In March, the first full trailer was released:
If this doesn't get you excited and a little freaked out, I don't know what to say!
What Is Disclosure Day About?
Through the aforementioned teaser and trailer, we’re starting to learn more and more about Disclosure Day and the adventure Steven Spielberg will be taking us on this summer. Though we don’t know exactly what the aliens look like, what they want, or how long they have been here, Universal Pictures has given us some hints at what the movie is about:
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.
What is that truth? Is this going to be a more polished and less cynical take on They Live? Or is this all some kind of misdirection? Either way, Spielberg’s filmography speaks for itself, especially when it comes to his output of great alien films.
Steven Spielberg Teamed Up With Longtime Collaborator David Koepp
The acclaimed filmmaker may have come up with the original idea behind Disclosure Day, but according to The Hollywood Reporter, Spielberg’s longtime collaborator David Koepp penned the script. Koepp, one of the director’s most prolific collaborators, previously worked with Spielberg on Jurassic Park, The Lost World: Jurassic Park, War of the Worlds, and Indiana Jones and the Kingdom of the Crystal Skull.
Despite that long professional partnership, it was a challenging assignment for Koepp. In fact, it took 42 drafts of the Disclosure Day script for Spielberg to sign off and start production. Koepp told Vanity Fair:
[Spielberg] was more exacting than I’ve ever seen him because he knows he’s worked in this area before. He wants this one to be the best one.
With the success of their previous collaborations, for the most part, it’s going to be exciting to see what these two icons of the industry have cooked up for audiences. It certainly sounds promising.
John Williams Composed The Disclosure Day Score
Few directors and composers’ careers have been tied to one another more than Steven Spielberg and John Williams. The two have worked with each other dozens of times over the past half-century. From bringing tension to Jaws to the wonder of Jurassic Park and E.T. to the tear-jerking music in Schindler’s List, these two have made one iconic movie moment after another. Well, these two got back together once again for Disclosure Day.
As seen and heard in the movie’s trailer, the prolific composer, who just can’t stop making music, crafted what is sure to be an intense, exciting, emotional, and transfixing soundtrack to the wonder and action on screen. Considering these two worked hand-in-hand for Spielberg’s other alien movies, it seems only fitting…
The day is almost upon us; let's hope we all survive!
