‘The Mandela Catalogue’ Movie From Steven Spielberg Sets Summer 2028 Release Date

Hollywood’s appetite for turning viral internet horror into theatrical box office gold has only intensified over the past year. What started as a niche experiment has quickly become one of the industry’s most reliable playbooks, with studios racing to snap up the rights to whatever analog horror phenomenon captures Gen Z’s attention next.

That trend reached new heights this year with ‘Backrooms’ and ‘Obsession,’ two YouTube-born horror properties that translated their massive online followings into genuine theatrical success, pulling in $394.1 million and $512 million globally, respectively. Those numbers have made every remaining major YouTube horror franchise an increasingly hot commodity among major studios.

Now one of the genre’s most beloved properties is officially getting its own big-screen treatment. ‘The Mandela Catalogue,’ the analog horror series created by Alex Kister, has set a theatrical release date of June 9, 2028, with Kister directing and Steven Spielberg producing through his Amblin Entertainment banner, according to details reported by Deadline.

The project comes from a partnership between Amblin, Scott Stuber’s United Artists, and Amazon MGM Studios, who reportedly beat out eleven other competing bids to secure the film rights. Kister is directing from a screenplay he adapted alongside Tyler Clifton, giving the franchise’s original creator direct creative control over how his world translates to the big screen.

Launched in 2021, ‘The Mandela Catalogue’ has become one of the defining titles within the analog horror genre, sitting alongside other cult favorites like ‘Local 58’ and ‘The Backrooms.’ The series is set in the fictional Mandela County, Wisconsin, a town invaded by shape-shifting, nearly immortal creatures known as Alternates who use psychological torment as their primary weapon against unsuspecting victims.

According to the franchise’s own wiki, the film adaptation will follow a group of recent high school graduates struggling to hold onto their grip on reality after a local student’s disappearance sets off a chain of unsettling, unexplainable events. Kister has previously described wanting the film to lean heavily on silence, dread, and the uncanny valley to unsettle audiences, blending traditional live-action footage with the found-footage aesthetic that made the original series so effective online.

The property has racked up more than 100 million views across its official YouTube episodes alone, making it one of the largest original analog horror franchises on the platform. That built-in audience gives the film adaptation a genuine head start compared to more traditional horror properties without an existing online fanbase.

Producing alongside Spielberg and Kister are Holly Bario for Amblin, Aaron B. Koontz for Paper Street Pictures, and Scott Stuber and Nick Nesbitt for United Artists, with Kister and Clifton also serving as producers on the project. Amazon MGM Studios negotiated the deal alongside Sarah Vacchiano representing United Artists, reflecting just how many parties were invested in landing this particular property.

Currently, the only other film scheduled for the same June 9, 2028 release date is an untitled event movie from Universal Pictures, giving ‘The Mandela Catalogue’ a relatively open lane compared to more crowded summer weekends. That said, the broader early-summer window remains competitive, with ‘Days of Thunder 2’ opening the week prior and Pixar’s ‘The Incredibles 3’ following just one week later.

Given how thoroughly ‘Backrooms’ outperformed expectations against major franchise titles like ‘The Mandalorian & Grogu’ earlier this year, Hollywood clearly believes YouTube-born horror properties can hold their own even in a stacked release calendar. Whether ‘The Mandela Catalogue’ can replicate that success remains to be seen, but the pedigree behind this adaptation, from Spielberg’s involvement to Kister’s direct creative control, suggests the studios are treating the project as a genuine tentpole rather than a quick cash-in.

With no cast or additional plot details revealed yet, fans of the original series will likely be watching closely for updates as production moves forward. Given how faithfully other recent adaptations have translated their source material’s unsettling tone to theaters, expectations for this one are already running high.
