NEW YORK (AP) — Days before “Obsession” opened in theaters, its 26-year-old director, Curry Barker, made a bet with his manager and agent. They said if the movie opened above $20 million, they would all get tattoos.“Obsession” fell just short. It debuted with $17 million. They were still thrilled. Barker made the horror film with just $750,000. It was enormously successful. But then something unexpected happened. The following weekend, “Obsession” easily cleared $20 million. And then it did again and again and almost a fourth time — an almost unheard-of staying power. “It was just like: Holy cow. I didn’t think that was an option,” Barker says. “Now we’ve said if it hits $300 million, we’ll all get the tattoo. We had to make a new milestone. And I think we’ll reach it.”Over the last month, “Obsession” has sent shock waves through Hollywood. Barker’s microbudget thriller has grossed $286 million worldwide, and it’s still going. On its fifth weekend in theaters, it was second only to Steven Spielberg’s “Disclosure Day,” with $19 million. In North America, it has outgrossed “Star Wars: The Mandalorian and Grogu.” It’s the biggest hit in the 24-year existence of Focus Features, which has had to postpone the video-on-demand release. It ranks among the most profitable movies ever made.
