Disclosure Day: Steven Spielberg's UFO Blockbuster Drops Explosive New Official Trailer
Steven Spielberg's most anticipated film in years just got a major new push. The official full-length trailer for Disclosure Day dropped on Thursday, March 12, 2026, giving audiences the clearest look yet at the summer sci-fi event film. The movie hits theaters nationwide on June 12, 2026, in IMAX, distributed by Universal Pictures.
What Disclosure Day Is About
The film asks one central question: if you found out we were not alone, if someone showed you and proved it to you, would that frighten you? The marketing frames the revelation as something shared by the entire planet, declaring that this summer the truth belongs to seven billion people — and that the world is drawing closer to Disclosure Day.
Josh O'Connor's character has access to long-held government secrets around the existence of beings not from Earth, with hints tied to Roswell, New Mexico. His plan is to become a whistleblower and share those secrets with everyone. Colin Firth's character intends to stop him at all costs. Emily Blunt plays a meteorologist who begins inexplicably speaking in tongues while on air, one of the film's most unsettling early images.
Disclosure Day Cast: A-List From Top to Bottom
Disclosure Day stars Emily Blunt, Josh O'Connor, Colin Firth, Eve Hewson, Colman Domingo, and Wyatt Russell. The ensemble was assembled quietly and deliberately by Spielberg himself — both O'Connor and Henry Lloyd-Hughes were offered their roles without having to audition.
The film is produced by five-time Academy Award nominee Kristie Macosko Krieger for Amblin Entertainment, with executive producers Adam Somner and Chris Brigham. The screenplay was written by David Koepp, whose previous collaborations with Spielberg include Jurassic Park, War of the Worlds, and Indiana Jones and the Kingdom of the Crystal Skull — scripts that combined earned more than $3 billion worldwide.
What the New Trailer Shows
The new official trailer is teeming with conspiratorial intrigue about what lies beyond the stars. It depicts the lengths people would go to in order to keep a massive secret from the public. Strange moments fill the footage — a deer walking with a young girl toward a glowing house, unexplained crop circles, high-tech eye-dilation devices, a terrifying train chase sequence, and deeply unsettling sounds woven throughout.
Colin Firth's character appears to use advanced technology connected to his mind to communicate remotely, even as his eyes change color — one of the trailer's most arresting visual details.
Spielberg Returns to His Roots
Disclosure Day marks Spielberg's return to the alien and sci-fi territory that made him a legend. The new film brings the director back to the genre that produced Close Encounters of the Third Kind and E.T., with the official trailer generating immediate comparisons to his most iconic work.
Disclosure Day will also be the first film from Spielberg following his achieving EGOT status, adding another layer of cultural anticipation surrounding its June 12 theatrical debut in IMAX.
