Backrooms, the new horror film directed by young filmmaker Kane Parsons, surprised the industry by reaching unprecedented box office numbers for A24 studios. Below, we detail the main financial indicators and the reaction of the public and critics.
Box Office Performance
In its first week of release, Backrooms grossed a total of $118 million worldwide. Of this amount, $81.5 million was generated exclusively in US movie theaters, far exceeding initial projections that pointed to a North American opening of around $20 million. The film’s financial success places it as the highest-grossing release ever recorded by A24.
- Worldwide box office: $118 million
- US box office: $81.5 million
- Initial US projection: $20 million
- Estimated production budget: between $8 million and $10 million
With a budget ranging from $8 million to $10 million, the return obtained in the first weeks represents an exceptional investment multiple, confirming the film as an immediate success for A24.
Critical and Public Reaction
The reception from specialized critics was generally positive, highlighting Kane Parsons’ direction and the film’s ability to turn the concept of “non-place” into effective horror. However, the general public presented more diverse reactions. CinemaScore gave the film a B- grade, an indicator that historically signals a tendency to more pronounced drops in revenue in subsequent weeks.
- CinemaScore grade: B-
- Specialized critics’ reaction: positive
- General public’s reaction: mixed
Despite the moderate CinemaScore grade, the combination of strong social media promotion, the viral origin of the “Backrooms” concept, and the support of a recognized studio like A24 contributed to the record-breaking opening performance.
Production Context
The film is born from a viral internet phenomenon, which transformed the concept of “Backrooms” – an infinite and labyrinthine space – into a starting point for horror narratives. A24, known for betting on risky projects with cult potential, financed the production with an estimated budget of between $8 million and $10 million. Director Kane Parsons, still early in his career, received full support from the studio to materialize the adaptation.
The success of Backrooms demonstrates A24’s ability to capitalize on digital culture trends, converting an internet meme into a profitable cinematic product.
Market Impact and Future Perspectives
The numbers achieved by Backrooms establish a new benchmark for low-budget releases within the horror segment. The return of $118 million in worldwide box office, against an investment of less than $10 million, raises the profitability index to around 12 times the production cost.
Industry analysts point out that, although the B- CinemaScore grade may indicate a slowdown in revenue in the coming weeks, the volume already collected puts the film in a comfortable position to reach even more ambitious profit targets, especially considering the potential for auxiliary revenue (streaming, merchandising, and licensing).
Furthermore, Backrooms‘ performance may encourage other producers to explore narratives derived from viral internet content, reinforcing the trend of convergence between digital culture and traditional cinema.
In summary, Backrooms not only broke A24’s box office records but also proved that low-budget projects, when aligned with contemporary cultural phenomena, can generate extraordinary financial returns.
