In an interview with Geeks of Doom, Cognetti has stated that he sees the
Hell House LLC trilogy as "one movie just divided into three acts and each movie is its own act". He further commented that he found it easy to write the second and third parts, as he knew "where I wanted to go with it from the get-go".
Hell House LLC II: The Abaddon Hotel Hell House LLC II: The Abaddon Hotel was released on Shudder on September 20, 2018. The film's plot centers around a group of journalists who have gathered to explore the Abaddon Hotel, which has once again been abandoned following the events of the prior film. The movie further fleshes out the character of Andrew Tully, a character introduced in the first film, and his goal of opening a gate to hell. None of the journalists leave the abandoned hotel alive. The sole survivor found by the police is revealed to have been dead all along and sent out to intrigue people into visiting the hotel.
Bloody Disgusting reviewed the film, criticizing it as a "well-intentioned misstep".
Hell House LLC III: Lake of Fire Hell House LLC III: Lake of Fire was released as a Shudder exclusive on September 19, 2019. The film is the third installment of the series. The film is styled as a documentary following Russell Wynn, a wealthy and mysterious entrepreneur who wants the Abaddon Hotel to serve as the location for an immersive theater experience called "Insomnia" based on
Faust. Although aware of the location's history, he is keen to proceed with the venture despite others warning him of ongoing and frightening supernatural events. This prompts the documentary team to investigate Russell's past and the prior two events, uncovering new footage that implies Russell was involved with or was monitoring events. When opening night arrives chaos ensues. However, Russell manages to wrestle Tully and overcome him before he can kill or take any other innocent lives. The following day one of the documentary crew muses that Russell was likely an angel sent back to defeat Tully and bring an end to his evil plans. Before the film ends, Russell manages to bring back the spirits of the original crew who died in the house, telling them that they are free from the evil but that the house still holds them captive. The song "Running Away" by the Pittsburgh based band "Post Traumatik" was used during the bar scene.
Film School Rejects was critical of the movie, stating that it was "an ambitious stab at closing out a horror trilogy, but as much as that’s an accomplishment worth celebrating the end result is an unfortunate disappointment. Still, fans of the first two — or even the first one — might find some worthwhile closure in the final swan song of the Abaddon Hotel." The film holds a rating of 14% on Rotten Tomatoes, based on 7 reviews.
Hell House LLC Origins: The Carmichael Manor Hell House LLC Origins: The Carmichael Manor was released on October 30, 2023, exclusively on Shudder. Written and directed by Stephen Cognetti, the film serves both as a prequel to
Hell House LLC (2015) and a sequel to
Hell House LLC III: Lake of Fire (2019), making it the fourth installment in the franchise. It stars Bridget Rose Perrotta, Destiny Leilani Brown, James Liddell, and Gideon Berger, and was produced by Joe Bandelli. The story follows Margot Bentley, a filmmaker and paranormal investigator, who travels with her girlfriend Rebecca Vickers and her brother Chase to Carmichael Manor in
Rockland County, New York. Their goal is to document the site of the unsolved Carmichael family murders from the 1980s. As they uncover hidden film reels and artifacts linked to the Abaddon Hotel, the group realizes the property’s connection to Andrew Tully’s cult. Over four nights, they experience increasingly violent supernatural events, leading to their disappearance. A mid-credits scene connects the events back to the Abaddon Hotel, suggesting the evil has spread beyond its walls.
Principal photography began in April 2023, with Cognetti emphasizing the film’s goal of expanding the series mythology beyond the hotel setting. It was produced under Terror Films and Cognetti Films, using a mix of found-footage and conventional cinematography. The film received positive reviews from critics and fans. On
