‘I Know What You Did Last Summer’ Slashes into $24 Million Worldwide Opening; But Is That Enough?

After three movies and a one-season television series, I Know What You Did Last Summer returned to the big screen over the weekend for the first time in 27 years, with Jennifer Love Hewitt and Freddie Prinze Jr. guiding a group of fresh faces through more or less the exact same situation their characters found themselves in back in the 1990s.

How did I Know What You Did Last Summer (2025) fare at the box office?

The slasher legacy sequel from Sony scared up an estimated $13 million in 3,206 theaters here in the United States, with the film’s worldwide opening weekend hitting $24.6 million.

At the domestic box office, the film’s $13 million opening placed it in the #3 spot on the weekend charts, behind recent big budget blockbusters Superman and Jurassic World Rebirth.

The good news for I Know What You Did Last Summer is that the film’s production budget was a reported $18 million, so it should end up being profitable at the box office when all is said and done. But the film’s $13 million opening is a far cry from the comparable Scream franchise’s $30 million domestic opening return back in 2022, and even further away from Scream VI‘s $44 million debut the following year. Both films went on to scare up well over $100 million worldwide, a landmark that I Know What You Did Last Summer isn’t likely to ever hit.

Unadjusted for inflation, the original I Know What You Did Last Summer debuted to $15.8 million back in 1997 and raked in $125.5 million total, while 1998’s I Still Know What You Did Last Summer debuted with $16.5 million and ended its run with $84 million.

My personal analysis of the situation? $24.6 million isn’t a terrible worldwide debut for this particular movie, and the budget being on the lower end certainly helps. But the lesson Sony is likely to learn is one they seem to have learned a few times over at this point: I Know What You Did Last Summer isn’t really a franchise that audiences are going to be flocking to see.

Even with no less than two sequel teases capping off director Jennifer Kaytin Robinson’s new movie, we’d be surprised to see this franchise back up on the big screen anytime soon.
