Pet Sematary 2 Release Date, Cast And Plot - What We Know So Far Pet Sematary 2 Release Date, Cast And Plot - What We Know So Far Paramount Pictures By Sam Skopp/May 25, 2021 1:20 pm EDT "Pet Sematary," released in 2019, was not the first work to bear that title. It was the latest in a lineage of various "Pet Semataries," so to speak. In its initial incarnation, "Pet Sematary" was a book by Stephen King before it was adapted into a film in 1989. That first movie included one notably horrific sequence, and it film received a sequel in 1992. Finally, the 2019 version of "Pet Sematary" drew from its source material's lineage in both book and film form while altering one key plot detail, albeit with King's approval.
