‘Obsession’ Is Taking over Hollywood, and It Could Become the Biggest Original Movie of the Decade

Hollywood loves a good underdog story, but few genres are as unforgiving to newcomers as horror. Even successful scary movies tend to open big and vanish just as quickly, rarely sticking around long enough to become genuine cultural phenomena the way tentpole franchises do.

‘Obsession‘ was never supposed to be the exception. Directed by first-time filmmaker Curry Barker on a shoestring budget, the film arrived in theaters without the marketing muscle or built-in fanbase that typically drives a horror movie’s box office trajectory.

What happened instead has become one of the most remarkable box office stories of the year. According to DiscussingFilm, ‘Obsession’ has officially become the fifth highest-grossing horror movie of all time, with some analysts believing it could still cross the $500 million mark and become the biggest original film of the entire decade.

That trajectory looked almost unthinkable when the film first opened. Produced for somewhere between $750,000 and $1 million and acquired by Focus Features for a reported $14 to $15 million, ‘Obsession’ debuted to a modest $17.2 million from 2,615 theaters, a solid but unremarkable start for a horror release.

What made the film different was what happened next. Rather than fading in its second weekend the way most horror movies do, ‘Obsession’ actually grew, jumping 39 percent to bring in $23.9 million, an almost unheard-of feat for the genre. Comscore’s head of marketplace trends, Paul Dergarabedian, called the surge one of the most unusual jumps he’d seen in more than three decades of tracking the box office, in comments to Variety.

That momentum never really stopped. ‘Obsession’ went on to surpass ‘The Blair Witch Project’s’ inflation-adjusted haul, overtook William Friedkin’s ‘The Exorcist’ as one of horror’s biggest earners, and eventually claimed the title of highest-grossing original horror movie of the century. Along the way, it also became the first film with a sub-million-dollar production budget to cross $200 million this century.

The film’s audience reception has played just as big a role in its staying power as its cultural buzz. ‘Obsession’ holds an impressive 94 percent score on Rotten Tomatoes alongside an A- CinemaScore grade, a rare combination for horror that helped fuel sustained word-of-mouth turnout well beyond its opening weekend. That kind of reception also placed it among a small handful of horror films to earn an A- or higher on CinemaScore since 2019.

With its global total climbing past $440 million and continuing to inch closer to the $500 million threshold, ‘Obsession’ now finds itself in rare company among horror’s biggest all-time earners, a list traditionally dominated by big-budget studio productions and long-running franchises rather than scrappy, first-time directorial efforts. Reaching that milestone would put Barker’s film in direct conversation with modern horror’s biggest blockbusters, a stunning outcome for a story that started as a low-budget passion project.

The success has also sparked broader conversation across the industry about the rise of young, internet-native filmmakers breaking into Hollywood, with Barker’s journey drawing comparisons to fellow breakout director Kane Parsons, whose own YouTube-born horror hit ‘Backrooms’ has followed a similarly unexpected path this year.

Whether or not ‘Obsession’ ultimately crosses the half-billion-dollar mark, its run has already reshaped what’s possible for original horror films in an industry increasingly dominated by sequels and franchises.
