“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 only a few weeks left until the film hits theaters, anticipation for Disclosure Day is only growing as new footage, early reactions and more story details continue to emerge. So, what exactly is Disclosure Day about? Hollywood Life breaks down the plot below.
Who Is in the Disclosure Day Movie Cast?
As seen in the teaser, Emily Blunt is in the cast, and she plays a Kansas City weatherwoman, who apparently falls victim to an alien-like effect when she stammers, then makes a clicking sound live on the air.
Josh O’Connor is also a main cast member. The rest of the crew features Colin Firth, Eve Hewson and Colman Domingo.

What Is Disclosure Day About? Plot Breakdown
Based on the latest trailers and official details released about the film, Josh O’Connor appears to play a cybersecurity expert and whistleblower who becomes entangled in a massive conspiracy surrounding extraterrestrial life. 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.
New footage has also revealed more about Emily 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, Colin 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 will be released to theaters on June 12, 2026.
