Obsession probably needed to make about $30 million to make a profit. The indie horror film was budgeted at around $750,000 and, after premiering at the Toronto International Film Festival last year, Focus Features paid $14 million for the rights to distribute it. Then, you estimate that about double the cost of the film is used to market it. So, very roughly, once Obsession hit $30 million or so, it was something of a success. That happened on day four. Since then, Curry Barker’s devilish horror film Obsession has gone on a box office run for the ages. While most films usually make most of their money on opening weekend, Obsession saw its grosses actually increase over multiple weekends, something that hadn’t happened for a wide release in decades. And, in the weeks since then, it’s held up incredibly well against not just other independent horror films, like Backrooms, but massive Hollywood productions such as Toy Story 5, Supergirl, and Disclosure Day. This weekend, that success continued as the film crossed another milestone. Over a very competitive July 4 holiday weekend in the U.S., Obsession came in 6th place, grossing $5.3 million. And that number was enough for the film to cross $400 million worldwide, with $245 million coming in domestically and $157 million coming in internationally.
