‘Backrooms’ and ‘Obsession’ Draw Gen Z Back to Theaters, Reshaping the Horror Box Office

A new generation of filmmakers is proving that viral internet culture can become major box-office business. Horror films Backrooms and Obsession have emerged as two of 2026’s biggest theatrical surprises, drawing massive Gen Z audiences and outperforming expectations despite modest production budgets.

Industry observers see the films as evidence that younger moviegoers are increasingly supporting original stories created by internet-native filmmakers rather than relying solely on traditional Hollywood franchises.

Both movies originated from creators who first built audiences online through YouTube and social media. Their success has sparked conversations about a new era of horror filmmaking, where digital communities, viral marketing, and creator-driven storytelling can generate blockbuster-level theatrical results.

‘Backrooms’ Becomes a Box Office Phenomenon

Produced by A24 and directed by 20-year-old YouTube creator Kane Parsons, Backrooms is based on the viral internet horror phenomenon known for its eerie endless hallways, fluorescent-lit rooms, and unsettling liminal-space atmosphere. Parsons first gained popularity through his YouTube series under the name Kane Pixels before transforming the concept into a feature-length film.

The film follows Clark, a furniture store owner who becomes entangled in a mysterious alternate dimension while his therapist attempts to uncover the truth behind his disappearance. The movie blends psychological horror, science fiction, and surreal imagery inspired by online creepypasta culture.

‘Backrooms’ Box Office Earnings

Backrooms shocked the industry by earning approximately $81.5 million domestically during its opening weekend and $118 million worldwide, despite being produced on a reported $10 million budget. The film became the biggest opening weekend in A24 history and one of the largest debuts ever for an original horror movie.

Industry reports noted that roughly 86% of the opening-weekend audience consisted of younger viewers, highlighting the film’s strong connection with Gen Z moviegoers.

‘Obsession’ Continues Its Surprise Box Office Run

While Backrooms dominated headlines with its explosive debut, Obsession has quietly become one of the year’s most profitable films.

Directed by YouTube creator Curry Barker, the psychological horror thriller centers on a young man who uses a supernatural wish-granting object called the “One Wish Willow” to win over his crush. However, his dream romance quickly spirals into a disturbing nightmare as the consequences of his wish become increasingly horrifying.

The film earned praise for its dark themes, intense performances, and commentary on obsession, control, and unhealthy relationships. Many critics and viewers have highlighted its ability to combine psychological horror with social commentary.

‘Obsession’ Box Office Earnings

Made on a reported budget of around $1 million, Obsession has become one of 2026’s biggest horror success stories. The film has earned approximately $104.8 million domestically and $148 million worldwide, delivering one of the strongest returns on investment in recent years.

The movie also generated exceptional word-of-mouth momentum, with reports showing that around 75% of its audience came from viewers aged 18 to 34, a demographic heavily dominated by Gen Z moviegoers. Theater counts even expanded during its theatrical run due to sustained demand.

Why Gen Z Is Showing Up

The success of both films reflects a major shift in audience behavior. Unlike traditional franchise blockbusters, Backrooms and Obsession were built around online communities that already had emotional connections to the creators and concepts.

Social media discussion, YouTube fandoms, TikTok clips, and viral internet culture helped generate organic excitement before release. Instead of relying on decades-old intellectual properties, these films tapped directly into Gen Z interests such as liminal horror, internet mythology, psychological storytelling, and creator authenticity.

As Hollywood searches for the next generation of theatrical hits, the success of Backrooms and Obsession suggests that some of the industry’s biggest future franchises may come not from traditional studios, but from creators who first built their audiences online.
