Kane Parsons’ feature film Backrooms is now streaming on HBO Max, arriving September 25, 2026. The release lands just days before Halloween, positioning the film as a key entry for horror audiences preparing for the fall season. iHorror notes that the title is part of a broader wave of new horror releases hitting streaming services this week.
The film marks the feature debut for Parsons, who is widely known online as Kane Pixels. The concept originated from his YouTube series of the same name, which he created at age 16. According to iHorror, Parsons achieved significant success with the feature film four years after launching the web series. The movie is co-written by Will Soodik.
The plot centers on Clark, played by Chiwetel Ejiofor, a failed architect and husband who now owns a struggling discount furniture store. Clark explores his life’s failures with his therapist, Dr. Mary Kline, portrayed by Renate Reinsve. During a session, Clark discovers a door in his store’s basement that leads to an extradimensional world. This space is filled with endless rooms that sporadically connect to one another, varying in form and size.
iHorror describes the film as part of a lineup ranging from slashers to psychological horror. The source does not provide box office figures, critical reception details, or additional cast members beyond Ejiofor and Reinsve. No further release dates or distribution details for other titles in the weekend lineup were specified in the provided packet.
