Kane Parsons' Backrooms is eyeing an opening above $35 million. Video game-style YouTuber Markiplier’s leap into feature filmmaking with Iron Lung has become a textbook case of how online creators are rewriting Hollywood’s success formulas, both in production and audience reach. His debut demonstrated that a built-in fanbase can translate into solid box-office performance, even for a modestly scaled horror project.

Now, another YouTuber, Kane Parsons, looks poised to take that momentum even further, as Backrooms storms toward what could be a record-shattering opening for an A24 horror film.

Kane Parsons’ Backrooms is not just another horror release from A24. It stands as a defining moment for a generation of creators who built their voices online before stepping into theatrical filmmaking. Tracking estimates suggest an opening well above $35 million, with projections climbing toward $50 million. That range would surpass the studio’s previous benchmark set by Civil War.

The scale of that potential debut becomes even more striking when viewed against the film’s reported $8 million budget. A performance in that range would position Backrooms as one of the most profitable horror ventures in recent years. It also reinforces how cost-efficient creator-driven projects can compete with traditionally financed studio films.

The rollout reflects a wider shift in industry thinking, where YouTube creators are no longer treated as outsiders. Filmmakers like RackaRacka, Chris Stuckmann, and Markiplier have all transitioned into directing with increasing studio backing. Their digital audiences translate into measurable ticket sales, making subscriber counts a new form of box-office leverage.

That same creator-driven momentum is not limited to openings, as another horror title is redefining what sustained success looks like.

Curry Barker’s Obsession is quietly rewriting the rules of horror performance at the box office. The film has become the first wide-release horror title in recorded history to post a second weekend that outpaces its opening. With more than $23 million in its sophomore frame, it demonstrates the power of word-of-mouth momentum.

Made on a reported budget of just $750,000, Obsession has already crossed $80 million globally. That level of return places it alongside genre landmarks like The Blair Witch Project and Paranormal Activity. It also reinforces the viability of low-budget horror as one of the most efficient investment lanes in modern filmmaking.

At its core, the film’s appeal lies in a tightly constructed premise centered on obsession, desire, and unintended consequences. Strong performances from a rising cast elevate the material into both a psychological thriller and a character-driven story. Its success aligns with the broader rise of creator-led cinema, linking projects like Iron Lung and Backrooms into a growing movement that studios can no longer ignore.
