“If you found out we weren’t alone, if someone showed you, proved it to you, would that frighten you?” the Disclosure Day trailer asks. Leave it to the great and powerful Steven Spielberg to bring a new, unnerving sci-fi movie into our lives after we were given the friendly E.T. the Extra Terrestrial, the frightening War of the Worlds adaptation and the eerie Close Encounters of the Third Kind.
With the film now playing in theaters and generating strong reactions from critics and audiences alike, many moviegoers are eager to learn more about the story behind Spielberg’s latest blockbuster. Below, Hollywood Life breaks down the plot of Disclosure Day.
Who Is in the Disclosure Day Movie Cast?
Disclosure Day features an ensemble cast led by Emily Blunt and Josh O’Connor. Blunt stars as a meteorologist who becomes entangled in a mysterious series of events tied to evidence of extraterrestrial life, while O’Connor plays a whistleblower investigating a far-reaching government conspiracy.
The rest of the crew features Colin Firth, Eve Hewson and Colman Domingo.

What Is Disclosure Day About? Plot Breakdown
Disclosure Day follows a cybersecurity expert and whistleblower, played by O’Connor, who becomes caught up in a far-reaching conspiracy involving extraterrestrial life and a decades-long cover-up. As evidence begins to surface, his character pushes for the truth to be revealed to the world, setting off a chain of events with global consequences. In one of the movie’s most unsettling moments, his character calls for “full disclosure, to the whole world, all at once” while standing inside a mysterious crop circle.
Other footage has also revealed more about Blunt’s character, a Kansas City meteorologist who seemingly becomes linked to the alien phenomenon after unexpectedly transmitting a strange message on live television. Meanwhile, Firth appears to play the head of a powerful corporation connected to the cover-up, with several scenes showing his character reacting in horror to what he witnesses while strapped into a chair with wires attached to his head.
Though fans have already dubbed Disclosure Day Spielberg’s latest “UFO-centered” movie, the film appears to focus just as heavily on government secrecy, paranoia and the emotional fallout of humanity learning it may not be alone. Early reactions from critics have also described the movie as one of Spielberg’s strongest sci-fi projects in decades, blending classic wonder with psychological thriller elements.
When Is the Release Date of Disclosure Day?
Disclosure Day was released exclusively in theaters on June 12, 2026. The Steven Spielberg-directed sci-fi thriller is now playing nationwide.
