Horror fans have been eating good recently. From breakout indie films to blockbuster revivals and a new wave of video games, the genre has been firing on all cylinders. Now, one of YouTube’s most influential horror series is making the leap to Hollywood, marking yet another mainstream milestone for horror. According to Deadline, Steven Spielberg is producing a feature film adaptation of The Mandela Catalogue, with Amblin Entertainment, United Artists, and Amazon MGM Studios set to produce it “following a highly competitive 11-studio bidding war.” The series creator, Alex Kister, is set to direct the film based on a screenplay he adapted with Tyler Clifton. cnx.cmd.push(function() {cnx({playerId: "106e33c0-3911-473c-b599-b1426db57530",}).render("0270c398a82f44f49c23c16122516796");});The involvement of multiple major studios points to a clear and rapidly growing appetite for adapting internet-native horror properties. What was once a niche corner of YouTube storytelling is now being treated as viable big-screen IP, as seen with the success of Curry Barker’s Obsession and Kane Parson’s Backrooms, which have brought in $374 and $331 million, respectively, at the box office so far. Launched in 2021, The Mandela Catalogue is set in the fictional county of Mandela, Wisconsin, where reality is disrupted by beings known as “alternates.” Through instructional warning videos and found footage encounters, the alternates are shown to take the form of loved ones and friends with the goal of driving their victims to suicide. The series has since amassed well over 100 million views across its 19 episodes, the first installment of the series having 11 million views alone, cementing itself as one of the defining titles of the genre alongside Local 58, The Walten Files, Gemini Home Entertainment, and more. But despite its success, its selection for a Hollywood adaptation has sparked debate among YouTube analog horror fans, with some arguing that other analog series—like the ones listed above—should take priority given the controversy surrounding Kister. In March 2024, Kister became the subject of online controversy after allegations circulated on social media accusing him of inappropriate behavior involving fans, including claims of grooming and boundary violations. Kister denied the allegations, calling them false and defamatory, and said he would address them in further detail, which he later did, denying both the grooming claims and that the series was fetish content. The situation sparked widespread discussion across the analog horror community, with fans divided over the claims and fellow creators unsure about their ties with Kister, resulting in the crew of The Mandela Catalogue to quit and a terminated deal for a VHS release of the series with Retro Release. Later, in April, one of the accusers retracted the allegations, which led to Kister promising that the series would continue.Still, the project underscores the turning point for horror as a whole, as another successful adaptation could open the door wider for more analog horror and internet-native storytelling to be adapted for film. At the same time, it raises questions about how these stories will translate beyond their original format going forward, with analog horror relying on fragmented storytelling, low-fidelity presentation, and audience interpretation that do not always map neatly into traditional cinematic structure. While Backrooms is now the prime example of how this kind of material can be adapted successfully, it remains to be seen how The Mandela Catalogue will handle the transition, as details about how faithful the film will be have not yet been revealed. Despite mixed feelings toward the series, The Mandela Catalogue represents one of the clearest signs that the horror genre is officially taking a turn towards niche, original, Gen Z-forward storytelling. Whether Hollywood fully understands what makes that kind of internet horror resonate, however, is a question that only the next wave of adaptations will be able to answer.The post YouTube Horror Just Scored One of its Biggest Movie Adaptations Yet appeared first on Den of Geek.
