Backrooms: Exploring the Eerie Practical Set and Its Impact on the Cast (2026)

The Haunting Reality of Filming in the Backrooms: A Deep Dive into Practical Horror

When I first heard about Renate Reinsve’s experience on the set of Backrooms, one thing immediately stood out to me: the sheer audacity of building a 30,000-square-foot practical set for a horror film. In an era where CGI and virtual production dominate, this feels like a throwback to a different time—a time when filmmakers relied on tangible, physical spaces to evoke fear. But what makes this particularly fascinating is the psychological toll it took on the cast. Reinsve’s admission that she feared going ‘a little bit insane’ isn’t just a dramatic flourish; it’s a testament to the power of practical sets in horror.

The Uncanny Valley of Space

The concept of the Backrooms—an endless labyrinth of off-kilter rooms and hallways—is inherently unsettling. It’s the kind of space that messes with your perception, blurring the line between reality and nightmare. Personally, I think this is where practical sets shine. You can’t replicate the feeling of standing in a room that’s just slightly wrong with CGI. It’s the subtle details—the way the walls seem to stretch, the eerie silence of an empty hallway—that trigger that primal sense of unease. What many people don’t realize is that this ‘uncanny valley’ of architecture is as effective as any monster or jump scare.

From my perspective, Reinsve’s concern about her mental health isn’t just a byproduct of the set’s size; it’s a feature, not a bug. Horror thrives on authenticity, and if the actor feels the dread, the audience will too. This raises a deeper question: How far should filmmakers go to create an immersive experience? Is it ethical to push performers to the brink of psychological discomfort for the sake of art? I don’t have the answers, but it’s a conversation worth having.

Existential Horror in the Age of AI

What this film really suggests is that Backrooms isn’t just a horror movie—it’s a commentary on our modern world. Reinsve’s tease about the film’s existential themes, particularly its exploration of AI, technology, and distorted psychology, is intriguing. If you take a step back and think about it, the Backrooms could be a metaphor for the endless, often irrational, digital spaces we navigate daily. Social media, virtual reality, even the internet itself—aren’t they all labyrinths where reality can warp and distort?

A detail that I find especially interesting is the film’s focus on how we make sense of the irrational. Reinsve mentions that sometimes, the only way to understand something nonsensical is through another nonsensical lens. This feels like a commentary on our current cultural moment, where truth is often obscured by layers of misinformation and manipulation. In my opinion, this is what elevates Backrooms from a simple horror flick to a thought-provoking piece of art.

The Rush of Modern Filmmaking

One aspect of Backrooms that often gets overlooked is its production timeline. Filming wrapped in just over a month, and the movie is set to hit theaters nine months later. This is a far cry from the multi-year production cycles of blockbuster films. What this really suggests is that horror, when done right, doesn’t need a massive budget or endless post-production. It’s about atmosphere, tension, and a good story.

Personally, I think this is a refreshing change. In an industry dominated by franchises and sequels, a tight, ambitious project like Backrooms feels like a breath of fresh air. It’s a reminder that sometimes, less is more—especially in horror.

Final Thoughts: The Future of Practical Horror

As I reflect on Backrooms and Reinsve’s experience, I can’t help but wonder if this marks a return to practical filmmaking in horror. In a world where CGI can create anything, there’s something uniquely terrifying about a physical set. It’s tangible, it’s real, and it can drive you a little bit insane—just ask Renate Reinsve.

What makes this particularly fascinating is the film’s potential to blend practical effects with existential themes. If Backrooms succeeds, it could pave the way for more films that prioritize atmosphere and psychological depth over spectacle. In my opinion, that’s the future of horror—and I, for one, am here for it.

So, will Backrooms live up to the hype? Only time will tell. But one thing’s for sure: it’s already sparked a conversation about the power of practical sets and the psychological toll of filmmaking. And in a genre as crowded as horror, that’s no small feat.
