Steven Spielberg is attached as a producer on a film adaptation of The Mandela Catalogue through his company Amblin Entertainment, which acquired the rights with United Artists and Amazon MGM Studios. His 2018 film Ready Player One is set to stream on Amazon Prime Video in August 2026.
Steven Spielberg's production company, Amblin Entertainment, is part of a three-way acquisition of the film rights to The Mandela Catalogue, a YouTube analog horror series. The deal, announced in July 2026, also involves United Artists and Amazon MGM Studios. The original creator, Alex Kister, will direct and co-write the script with Tyler Clifton. The series, which began in 2021, is set in a fictional Wisconsin county and features alien beings called Alternates that impersonate humans.
Separately, Spielberg's 2018 film Ready Player One is included in Amazon Prime Video's August 2026 streaming lineup. The announcement, made on July 31, lists the film among new additions that also include four Odoru Daisousasen theatrical films, the Puella Magi Madoka Magica series and movies, and both Naruto anime series. The lineup spans Japanese and international films, dramas, anime, and variety content.
The two stories place Spielberg in both a producing role on a new adaptation and a catalog presence on a major streaming platform. The Mandela Catalogue project marks a move of an internet-born horror property into major Hollywood production, continuing a trend of online horror being picked up by the film industry.
