Disclosure Day Cast and Crew: Who Plays Who, Who Made It, Where to Stream It

Disclosure Day, Steven Spielberg’s UFO thriller released by Universal on June 12, 2026, stars Emily Blunt as a Kansas City TV weather reporter and Josh O’Connor as a cybersecurity specialist turned whistleblower, with Colin Firth, Colman Domingo, Eve Hewson and Wyatt Russell around them. Behind the camera Spielberg reassembled his longest-running team, from screenwriter David Koepp to composer John Williams on their 30th film together.

The short version: The Disclosure Day cast is led by Blunt as Margaret Fairchild, with O’Connor as Dr. Daniel Kellner and Firth as Wardex chief executive Noah Scanlon. Spielberg wrote the story and Koepp the screenplay, Janusz Kaminski shot it, and Michael Kahn and Sarah Broshar cut it. The film grossed $244,361,229 worldwide by The Numbers’ count and has streamed exclusively on Peacock since October 9, 2026. This guide stays light on plot; character descriptions come from the studio and Peacock.

The Disclosure Day cast and who they play

Character names below follow The Numbers’ credits listing, and the descriptions come from Peacock’s guide to the film, which describes the leads as “meteorologist Margaret Fairchild,” “cyber security specialist Dr. Daniel Kellner” and “Wardex CEO Noah Scanlon,” among others.

Actor Character Who they are
Emily Blunt Margaret Fairchild Kansas City TV weather reporter
Josh O’Connor Dr. Daniel Kellner Cybersecurity specialist turned whistleblower
Colin Firth Noah Scanlon Chief executive of Wardex
Colman Domingo Hugo Wakefield Disclosure advocate
Eve Hewson Jane Blankenship Former nun, Daniel’s girlfriend
Wyatt Russell Jackson Margaret’s boyfriend
Henry Lloyd-Hughes Casper Boyd Supporting role
Elizabeth Marvel Nun Supporting role
Elliot Villar Agent Diaz Supporting role

Margaret is the story’s anchor. Peacock describes her as “a Kansas City reporter who experiences an odd ‘event’ while broadcasting live that changes the course of her life forever,” and TheWrap summed up the film’s central pairing as “a television weatherwoman (Emily Blunt) and a cybersecurity expert-turned-whistleblower (Josh O’Connor).” Blunt explained the appeal in the film’s press notes, quoted by Peacock: “She is in a situation where she is way over her head.” She called characters like Margaret “ordinary yet interesting people thrust into extraordinary circumstances.” Our separate explainer on Emily Blunt’s role goes deeper on the character.

The supporting list also includes Michael Gaston and Patricia Conolly, whose character names The Numbers does not list. For a role-by-role look written before release, see our earlier Disclosure Day cast guide.

Spielberg and Koepp: how the script was written

The credit reads story by Steven Spielberg, screenplay by David Koepp, and the order reflects how it happened. According to TheWrap, the film “started in the summer of 2023, when Koepp received a 40-page document from Spielberg.” When Koepp asked what it was about, Spielberg answered, “Aliens again.” Koepp sent back notes, Spielberg revised, and eventually Spielberg asked, “Why don’t you write it?” Koepp’s reply: “I thought you’d never ask.”

The writing then ran, in Koepp’s description, through two years and 42 drafts. He compared the result to 1970s paranoia thrillers: “It felt like ‘Three Days of the Condor’ to me – they have this information, they have got to get it out and everyone is trying to stop them.” He also said “it was important to Steven that we use as much existing lore as possible,” which is why familiar UFO stories turn up in the film.

The partnership is a long one. TheWrap points out that Koepp wrote Jurassic Park for Spielberg at age 29, and that they reunited for The Lost World in 1997, War of the Worlds in 2005 and Indiana Jones and the Kingdom of the Crystal Skull in 2008. Koepp framed Disclosure Day as “a kind of bookend to ‘Close Encounters of the Third Kind.’” Spielberg made the same link in the press notes, recalling that while making the 1977 film he would ask himself: “Wouldn’t it be wonderful if all of this turned out to be true?”

The Numbers lists Atlanta, Georgia among the filming locations, along with New Jersey and New York, and classifies the film as an original screenplay rather than an adaptation. Peacock counts it as Spielberg’s 37th feature, and his first UFO film since War of the Worlds in 2005.

John Williams’ 30th Spielberg score

Classic FM counts Disclosure Day as “the 30th collaboration between John Williams and Steven Spielberg,” a partnership that began with The Sugarland Express in 1974. Williams’ involvement was confirmed in October 2025, when he was 93, and Classic FM reported that he first suggested four other composers to Spielberg before agreeing to do it himself.

Spielberg has described the music as unusually quiet: “Disclosure Day is probably the most restrained score he has ever written for one of our collaborations – at least until it is not.” He added: “It is like he is accompanying the film from slightly behind it, pushing it forward.” Our piece on the Disclosure Day score covers the anticipation before release.

Box office, reviews and rating

Universal opened the film wide and in IMAX on June 12, 2026. The Numbers records an opening weekend of $44,530,925 from 3,824 theaters, and final grosses of $116,636,645 domestic, $127,724,584 international and $244,361,229 worldwide, against a production budget it lists as $115,000,000. Peacock’s own write-up rounds the global figure to $241 million; the small gap is a difference between sources rather than new grosses.

Reviews leaned positive without being unanimous. Checked on October 11, Rotten Tomatoes shows a 79% Tomatometer from 442 reviews and a 69% Popcornmeter from verified audience ratings. Its critics’ consensus credits “career-highlight work by Emily Blunt.” The film is rated PG-13 “for action/violence, some bloody images and strong language,” and runs 145 minutes. Not every outlet was won over: Space.com’s review called it a “close encounter with Spielberg’s brilliance that doesn’t quite make contact.”

Where to watch Disclosure Day now

Universal Home Entertainment released the film on video on July 21, 2026, according to The Numbers. Peacock’s guide, updated October 9, 2026, says it “is now streaming exclusively on Peacock,” and Space.com reported the start date as October 9, 2026. Rotten Tomatoes’ listing also shows rental and purchase through Fandango. That exclusivity is why the answer to whether Disclosure Day will be on Netflix is, for now, no.
