A Pacific Rim prequel series is being developed by the scriptwriter of Bird Box
It will be an origin story for the Pacific Rim universe.
The next entry in the Pacific Rim franchise could be an origin story for the universe, set before the events of the 2013 film by Guillermo del Toro. According to Variety, the franchise's producer Legendary Entertainment has signed a first-look TV deal with Eric Heisserer. One of the first projects he's developing with Carmen Lewis, his co-founder for his production company called Chronology, is a prequel series for Pacific Rim. Heisserer won several awards for his screenplay for Arrival, the Denis Villeneuve-directed sci-fi movie starring Amy Adams and Jeremy Renner. He also wrote the script for the Netflix post-apocalyptic movie Bird Box, which starred Sandra Bullock.
It sounds like the project is still in its very early stages, so we'll have to wait for its storyline and projected release date if it does get the green light. Seeing as it's supposed to be the Pacific Rim origin story, though, we may get to see the first kaijus emerging from the interdimensional portal at the bottom of the Pacific Ocean. We may also get to see how the first Jaegers, or the gigantic mechas controlled by human pilots to fight the alien monsters, were designed and created.
The original Pacific Rim movie was followed by Pacific Rim Uprising, its 2018 sequel film that starred John Boyega and was directed by Steven S. DeKnight. If the series pushes through, it'll follow Pacific Rim: The Black, an anime series that streamed on Netflix in 2021 and 2021, which serves as the continuation of the two films.
