'Backrooms' Trailer, Release Date Revealed, What To Expect From Ejiofor And Reinsve's Horror?

A24 has shared the first trailer of Backrooms, and it already gives a very strange and uneasy feeling. The film stars, Chiwetel Ejiofor and Renate Reinsve, and it follows a story where a normal place suddenly opens into something that should not exist. Directed by Kane Parsons, the film is based on his viral YouTube series. It is set to release in theatres on May 29, 2026, and the early look shows a world where getting lost might mean never coming back.

Kane Parsons's 'Backrooms' film is based on a viral YouTube series and urban legend

The story comes from a very popular internet idea known as the Backrooms. It started as an online urban legend and later grew into a full video series created by Kane Parsons in 2022. His videos showed empty spaces that looked normal at first but slowly felt wrong and endless. Now, the film builds on that same idea. This time, the story centres around a strange doorway that appears inside the basement of a furniture showroom. It looks like a normal space that turns into a maze of rooms that do not follow any logic.

Parsons, who was just 19 when he teamed up with A24, brings his original vision into a full-length film. This is his first feature project, and that makes it even more interesting because his earlier work already had a strong following online. The screenplay is written by Will Soodik, who has taken the internet concept and shaped it into a structured story with characters and tension that grow step by step.

Chiwetel Ejiofor, Renate Reinsve, and Mark Duplass lead the 'Backrooms' cast with a strong lineup

The film brings together a mix of well-known and rising actors. Chiwetel Ejiofor and Renate Reinsve lead the story, and both are known for taking on intense roles. Along with them, the cast includes Mark Duplass, Finn Bennett, Lukita Maxwell, and Avan Jogia. Each actor brings a different energy, which helps the story feel more grounded even when the setting becomes confusing. 

From the Backrooms trailer, it looks like the characters are trying to understand where they are, but nothing around them gives clear answers. One moment from the trailer stands out when a voice is heard, “You don’t walk into this place. It pulls you in.” That line sets the tone and hints that the danger is not always visible but always present.

James Wan, Shawn Levy, and producers back A24's 'Backrooms' film production details

The film is supported by a large production team. James Wan and Shawn Levy are part of the producers, along with Michael Clear, Roberto Patino, Dan Cohen, Dan Levine, Osgood Perkins, Chris Ferguson, Peter Chernin, Jenno Topping, and Kori Adelson. Production companies involved include North Road Films, 21 Laps Entertainment, Atomic Monster, and Phobos. A24 is handling the release and is also working closely with Chernin Entertainment as a co-studio.

The technical side of the film also adds depth. Cinematography is handled by Jeremy Cox, which shapes how the strange spaces are shown on screen. The music comes from Edo Van Breemen and Kane Parsons, helping build tension in each scene. Editing is done by Greg Ng, which plays a big role in how the story flows and how the fear builds slowly. Filming took place in Canada in July, and the project has now moved into its final stage before release.

What to expect from 'Backrooms,' an A24 sci-fi horror film experience

From what the Backrooms trailer shows, this film is not about fast scares. It builds a feeling that something is wrong, even when nothing is happening right away. The spaces look empty, but they do not feel safe. Long hallways, repeating rooms, and strange lighting create a sense that there is no way out. The story focuses on being stuck in a place that keeps changing and does not follow normal rules. The trailer contains a second line which states, "If you hear something, don’t follow it." The scene demonstrates that sounds have the power to draw people into hazardous situations. The movie will present its tension through a gradual progression which leads to increasing suspense.

Backroom shows its characters experiencing confusion and unknown fear while they battle against complete disorientation, instead of showing them fighting against monsters which create unexpected events. The film will achieve its storytelling balance through a combination of its talented cast and its skilled production team. The study examines two elements, which include the physical environment and the human response to realising their inability to escape from situations they cannot comprehend. Backrooms stands out as a distinctive 2026 horror movie because of its combination of online content and traditional film techniques, which creates an experience where viewers lose track of what is genuine.
