Steven Spielberg Promises DISCLOSURE DAY Trailers Won’t Spoil the Movie’s Biggest Secrets
If you’ve been burned one too many times by trailers that give away the entire plot, Steven Spielberg has some reassuring news about Disclosure Day. The filmmaker is taking a different approach with this one, making sure audiences can walk into the theater without already knowing how the story plays out.
While appearing at CinemaCon 2026, Spielberg reassured audiences that the marketing campaign has been handled with extreme care.
While at the event, Spielberg said he was very careful and protective of not revealing the third act in any of the trailers or previews. That means whatever chaos, revelations, or emotional punches are waiting in the finale are still completely under wraps.
That’s a pretty refreshing promise, especially right now when trailers often feel like condensed versions of the entire movie. Spielberg seems determined to keep Disclosure Day mysterious, letting audiences actually experience the story unfold in theaters instead of piecing it together months in advance.
The film leans hard into that mystery. Its 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." It’s the kind of setup that hints at something massive without spelling out exactly what’s coming.
The first trailer followed that same approach. It introduced Emily Blunt as a weather presenter who suddenly begins speaking in an alien language during a live broadcast. It’s unsettling, confusing, and interesting. Things only get stranger when Josh O’Connor enters the picture, teaming up with her as bizarre events start piling up around them.
But the footage shown at CinemaCon took things a step further. The new trailer we were shown finally offers a look at the extraterrestrial threat. O’Connor’s character comes across footage of alien bodies, while Blunt witnesses something far more disturbing, a deer transforming into a large grey alien right in front of her.
There’s also a hint that their connection runs deeper than it first appears. The preview suggests they may share a past involving abduction as children, which could explain why O’Connor can understand the strange language Blunt is speaking.
As he gets closer to figuring everything out, things escalate fast, with government agents chasing him down in a high-speed sequence.
The project also marks a reunion between Spielberg and David Koepp, the writer behind Jurassic Park, which should give fans a solid idea of the kind of tension and scale this story might deliver. The cast is rounded out by Colin Firth, Eve Hewson, and Colman Domingo, adding even more weight to an already strong lineup.
With Spielberg holding back the film’s biggest moments and only teasing fragments of what’s to come, Disclosure Day looks like one of those rare blockbusters where the unknown is part of the experience.
If he sticks to that promise, audiences might actually get to walk into a sci-fi movie without already knowing how it ends.
Disclosure Day lands in theaters on June 12, 2026.
