The official trailer for Backrooms has finally arrived, and it delivers a deeply unsettling look into one of the most anticipated horror films of the year.
Based on the viral internet phenomenon created by Kane Parsons, the film expands the eerie concept of endless, empty spaces into a full-scale cinematic nightmare. The trailer showcases a world of dimly lit hallways, fluorescent yellow rooms, and disorienting architecture, capturing the same unsettling tone that made the original YouTube series a global sensation.
The story centers on a man, played by Chiwetel Ejiofor, who claims to have discovered a strange alternate dimension hidden behind reality itself. When his therapist, portrayed by Renate Reinsve, begins to investigate his claims, she is drawn into the terrifying labyrinth where logic breaks down and escape may be impossible.
The trailer leans heavily into found-footage aesthetics and liminal horror, blending low-fi analog visuals with large-scale production design. This combination preserves the raw, unsettling feeling of the original material while expanding it into a more structured narrative experience.
Directed by Parsons in his feature debut, the film represents a rare case of an internet-born horror concept successfully transitioning to a major theatrical release. Backed by A24 and producers including James Wan, the project has quickly become one of the most talked-about genre films of 2026.
Backrooms is set to release in theaters on May 29, 2026, positioning it as a major summer horror event.
With its haunting visuals and deeply disorienting premise, the film looks ready to bring liminal horror into the mainstream in a way few projects have managed before.
