News Backrooms What the Backrooms Movie Doesn’t Tell You About the YouTube Series’ Lore There is so much more to the Backrooms than what you saw in the movie By Matthew Byrd | Published on June 2, 2026 Image: A24 Comment 0 Share New Share Image: A24 This article contains spoilers for the 2026 Backrooms movie and the Backrooms YouTube series Backrooms becoming one of the biggest box office hits of 2026 (so far) is the culmination of a rather remarkable creative journey. What began as a random photo of a liminal space in an abandoned furniture store that began making the rounds online sometime in the 2010s eventually grew into a creepypasta legend about the backrooms: an infinite series of similar rooms you can accidentally fall into and never escape. That horrifying idea eventually became the basis for a series of YouTube shorts created by Kane Parsons, who, in turn, recently directed and co-wrote the Backrooms movie. And while there are threads that bind the original backrooms photos to the original movie, the connection between those YouTube shorts and the recently released film is much stronger. The movie is, for all intents and purposes, a continuation and, in some ways, a culmination of the story presented in those shorts. That story began as a video of a person who accidentally falls into the backrooms but soon grew into a sweeping epic with a mythology as vast and confusing as the backrooms themselves. In fact, the YouTube series actually goes into far greater detail about plot points that the Backrooms movie either only hints at or doesn’t reference at all. And while it’s a fool’s promise to suggest that anyone can easily explain the entirety of the backrooms lore (so much of it is intentionally unknowable), there are a few of the more pressing pieces of lore you may not know about if your first trip into the backrooms was via the movie. Async’s History and True Purpose The Backrooms movie doesn’t properly introduce the Async corporation until the very end and keeps their purpose, origins, and methods somewhat vague. The only thing it really tells us about them is that they used to make MRI machines and know about the backrooms. The film gives the impression that we’re simply not meant to know about this shadowy organization. In reality, the Backrooms YouTube series explains quite a bit about Async’s true nature. Yes, Async used to manufacture medical equipment (primarily MRI machines). However, the nature of their work changed quite dramatically in the late 1980s when they decided to continue the research conducted by an organization known as the Oak Ridge National Laboratory. That research facility was working on a device known as the Low-Proximity Magnetic Distortion System (later referred to as “The Threshold”). It’s an electromagnetic field generator that was seemingly capable of accessing a vast, inexplicable space. That space is often offhandedly referred to as “the backrooms,” though Async began officially referring to it as the “Complex” and unofficially referring to it as the “Hallways.” Why does Async care about the Complex in the first place? Their idea was that the seemingly infinite space could be used to solve everything from global housing shortages to storage issues. Essentially, they saw it as the greatest real estate opportunity in the history of mankind. The idea was so popular that Async even began receiving government funding to help continue their research. The extent of Async’s exploration of the Complex is massive. Think of the Complex as a frontier. Or, maybe more accurately, think of it as a galaxy that a Federation-level organization is exploring in the distant future. They sent teams of researchers to set up stations in every corner of the Complex they could access. What began as an effort to map the area for eventual commercial purposes soon proved to be a futile endeavor. It wasn’t just that the space was massive; Async researchers soon found that the architecture of the Complex made no sense. Rooms violated the laws of physics and would often even shift. Any intentions to use that space in a productive way were slowly pushed aside when Async began to understand that they could never really tame what they had discovered. As you probably know, Async’s exploration of that space also soon revealed a number of horrors that converted them from explorers to reluctant guardians. Did Async Create the Backrooms? It’s not entirely clear whether Async created the backrooms or simply discovered them. A popular theory suggests that the Complex always existed in some form or another and that Async simply opened a door that led to the area. However, given that the Complex seems to be at least partially based on variations of our reality, another theory argues that the Low-Proximity Magnetic Distortion System actually created the Complex space rather than simply unlocked it. One possible argument for the “discovery” of the backrooms rather than their creation is the fact that it took Async multiple tries to successfully access the Complex for a prolonged period of time. It wasn’t until the sixth test of that technology that they were really able to create a sustainable doorway to the area. That successful test coincided with a massive earthquake along the San Andreas fault that killed hundreds and injured thousands. That would seem to suggest that they really created a dangerous gateway, but again, it’s an unanswered question at the moment. Time Distortion One element of the Complex that the Backrooms movie doesn’t really dive into is the idea that time (much like space and architecture) doesn’t function normally in that area. The specifics of the differences between how time works in that area compared to our world are left intentionally ambiguous. There are actually competing theories among fans about the nature of time in that space. Some argue that time moves slower in there, while others say it’s actually faster. A few theories suggest that it depends on what area you’re in, and a popular idea argues that time ceases to function in the traditional sense in our world so long as you are navigating the Complex. There is also the more complicated idea of temporal anomalies. Basically, being in the Complex isn’t just a matter of figuring out the hour, day, week, or year. There’s also the idea that the entire area exists at the convergence of multiple timelines. At the very least, the Complex has displayed evidence of distortions and temporal anomalies that strongly suggest it is not limited to our perception of traditional realities. So while the film focuses on a slightly smaller story based on a core group of characters, the nature of that space is much greater than what we are focusing on at any given moment. Missing People Arguably the most important element of the Complex that the Backrooms movie only hints at are the various missing people who accidentally found their way into that space at some point. We see people go missing there, and the movie references the idea that doors into the Complex are opening up more frequently, but it undersells the scope of the problem. Since the Complex was “opened” in 1989, there has been a dramatic spike in reported missing persons cases. The exact number of missing persons is unknown, but you’re potentially talking about hundreds of people that accidentally wandered into the backrooms via one portal or another, if not more. The first Backrooms video Parsons ever created (though not the first chronological video in the series) involved a young filmmaker who fell into the backrooms via an unseen portal underneath his feet. This also brings us back to the time distortion element of the whole thing. See, Async members have not only discovered some of those missing people in the Complex but, in some cases, discovered decomposed versions of those people in rooms where they weren’t just shortly before (at least in terms of how we perceive time). We again catch a hint of this concept in the movie when we see the tattered clothes of one of the soon-to-be-missing people in one of the Complex’s rooms, but it’s the missing people that have really accelerated the need for Async to get a hold of this situation. The Lifeform The Backrooms movie invokes the idea that the Complex contains variations of real-life individuals who have been mutated in various ways. We see at least one of those individuals (Pirate Clark) behave violently, but the film also suggests that these mutations are not inherently dangerous. For that matter, the movie seemingly offers a pretty big answer to a major backrooms lore question by saying that the space is, at least in part, essentially perpetual copies of our reality, mutations of ourselves included. In the Backrooms YouTube series, though, there is another threat we don’t clearly see in the film: an entity commonly referred to as The Lifeform. The Lifeform is a tall, gangly creature that is seemingly born from the black mold-like substance that is found throughout the Complex. Like many elements of the Complex, the exact origins of this creature remain unknown. The idea that it is born from this strange bacteria which somehow appears native to the Complex hints that The Lifeform was, in fact, born from these rooms. However, arguing for that idea also forces you to determine whether or not you believe that Async created these rooms and whether or not their presence/experiments may have altered them in ways that led to The Lifeform’s creation. Actually, a popular theory suggests that The Lifeform is able to alter its form by consuming or even just examining some of the objects it finds that have been left behind by Async researchers. Regardless, The Lifeform is consistently hostile in ways that the doppelgangers seen in the film are not. It is hostile to anyone it encounters, and Async researchers began to pack weapons in the (sometimes vain) hopes of defending themselves against it. What that says about The Lifeform in relation to the mutations we see in the movie is another mystery. Perhaps its openly hostile nature suggests a fundamental difference between it and the copies, or maybe the copies themselves are some sort of variation of the material and methods that resulted in The Lifeform’s existence.
