Marvel Television had certainly flirted with the horror genre before, including the recurring appearance of Ghost Rider (Gabriel Luna) on “Agents of S.H.I.E.L.D.,” but they fully embraced it with “Helstrom.” Streaming on Hulu in 2020, the series is based on hellish Marvel superheroes Daimon (Tom Austen) and Ana Helstrom (Sydney Lemmon), reimagined as the children of a satanic serial killer. Because of their parents’ cultist activities, Daimon and Ana develop paranormal powers that they use to root out evil. However, Daimon is secretly possessed by a demon and targeted by a cult that seeks to unleash it on the world.
While “Helstrom” was in the midst of principal photography in December 2019, Marvel Television was disbanded by its new parent company Marvel Studios. Previously, Marvel Television had been part of a separate parent company, Marvel Entertainment, and produced “Agents of S.H.I.E.L.D.” and Marvel’s Netflix original programming. After Marvel Studios absorbed Marvel Television in October 2019, its head Jeph Loeb stepped down, while Marvel Studios planned its own television content. This corporate restructuring led “Helstrom” to be released with little fanfare in October 2020 and quietly canceled two months later.
