Focus Features did not exactly lack ambition when it put Obsession into wide release. Still, few expected the microbudget horror-romance thriller from Curry Barker to become an Obsession box office hit on this scale. By June 2, the R-rated original had earned $161.5 million worldwide, according to Box Office Mojo figures, turning a film made far outside the franchise machine into one of 2026’s most surprising theatrical stories.

Here’s why that matters: this is not the usual summer math. No major stars. No built-in brand. No expensive superhero wardrobe quietly eating the budget. Just a creepy wish object, a young audience that showed up, and the rare horror film that got bigger after opening weekend.

How big has Obsession become at the box office?

Obsession opened domestically on May 15 in 2,615 theaters and took in $17.2 million in its first weekend. That would have been a strong start on its own for an original horror film. Then it did the odd thing: it climbed.
