Young couple Tom and Gemma are looking for a home when a strange real estate agent introduces them to a new suburban development where, he claims, houses are selling fast. But when they arrive, they find an eerie neighborhood of identical homes with no residents in sight. Every attempt to leave only brings them back to the same place, until, with no way out, they decide to spend the night in one of the houses.

Vivarium feels especially close to The Backrooms because of its endless, repeating environment — a space made unsettling by its artificiality and sameness, where every attempt to escape only leads the characters back to where they started.

A group of strangers wakes up inside a massive, mysterious structure made up of countless cube-shaped rooms. As they make their way through the maze of identical chambers, they realize the place is filled with hidden traps left behind by someone unknown.

Both films are built around a mysterious maze of rooms governed by rules the characters have to figure out as they go. Cube also feels close to The Backrooms because of its intense claustrophobic isolation, where every move from one room to another becomes a source of tension, and the entire space feels like one endless artificial trap.

The crew of the paranormal investigation show Grave Encounters agrees to spend the night inside an abandoned psychiatric hospital surrounded by eerie legends. At first, it feels like just another staged episode, until genuinely terrifying things begin happening inside the hospital.

Grave Encounters feels especially close to The Backrooms because its psychiatric hospital seems to exist in a space of its own, where the normal laws of physics no longer apply and escape becomes impossible. Like The Backrooms, it is filled with long, empty corridors, doors and windows that stop working the way they should, and a found-footage style that makes the experience feel even more intense.

Led by Scarlett, a group of young explorers enters the Paris catacombs in search of the legendary Philosopher’s Stone. But the deeper they go, the more the tunnels seem to turn into a place where buried guilt, old wounds, and hidden fears come crawling back.

The film will be interesting to those who liked The Backrooms’ idea of crossing from the ordinary world into a separate hidden space that follows its own rules. The characters’ journey through the labyrinth of the catacombs gradually turns into a psychological and claustrophobic trap, with no guaranteed way out and an increasingly strong sense of hopelessness.

Brothers Justin and Aaron return to the isolated Camp Arcadia, a community they once fled after believing it to be a dangerous UFO cult. As they try to make sense of the seemingly peaceful group, they begin to suspect that the supernatural force at the heart of its beliefs may be real.

Here, the similarity lies in the fact that both films are about an anomalous zone where reality begins to work differently, and the characters are not simply lost, but seem to have entered another space. The film works very well thanks to its intellectual side and atmosphere, where the presence of some greater force is always felt, even if it is not always physically manifested.
