After more than two decades since War of the Worlds, Steven Spielberg is officially returning to the extraterrestrial genre with Disclosure Day. At a landmark CinemaCon presentation on April 15, 2026, the legendary director unveiled the first look at what he describes as a film "way closer to truth than to fiction." The project, which reunites Spielberg with Jurassic Park screenwriter David Koepp, is being positioned as a "revolutionary" exploration of human-alien contact in the modern age. 'Disclosure Day' Trailer Out: Emily Blunt Runs for Her Life After Contacting Aliens in Steven Spielberg's Directorial.

‘Disclosure Day’ Plot

The film’s secretive final act centres on two ordinary individuals caught in a global sci-fi mystery, led by Emily Blunt as Margaret Fairchild, a Kansas City meteorologist whose life spirals when she suddenly begins speaking in a clicking alien language during a live broadcast, sparking worldwide panic. Opposite her, Josh O'Connor plays Daniel Kellner, a cybersecurity expert and whistleblower who has uncovered classified proof of non-human intelligence and is uniquely able to translate Margaret’s speech. Standing in their way is Colin Firth as Noah Scanlon, a powerful figure linked to the secretive Wardex corporation, determined to suppress the truth at any cost, setting up a high-stakes narrative of disclosure, conspiracy and global tension.

Steven Spielberg Teases Alien Thriller

Spielberg revealed at CinemaCon that the film was inspired by the 2017 New York Times report on the Pentagon’s Advanced Aerospace Threat Identification Program. “I really, truly believe this movie is going to answer questions,” Spielberg told the audience. “And this movie is also going to cause you to ask a lot of questions.” The footage shown in Las Vegas suggested a dark, X-Files-esque tone, featuring flashbacks of the main characters being experimented on as children by "little gray aliens." One particularly eerie scene shows a non-human hand reaching out to caress a human face, emphasising a focus on direct, intimate interaction rather than just spectacle. Christopher Nolan Unveils Extended Video From 'The Odyssey' at Cinemacon 2026.
