Why I Know What You Did Last Summer Box Office Projections Have Been Slashed

by

Fans of horror movies are eagerly anticipating the box office performance of the upcoming movie “I Know What You Did Last Summer” (2025), set to release in the U.S. on July 18. Initially, there was optimism that this fourth installment of the IKWYDLS film series, which dates back to 1997, would resonate with nostalgia. However, recent projections for its success have decreased significantly since June. Various analyses suggest that the film is not meeting expectations due to several reasons.

What are the box office predictions for I Know You Did Last Summer 2025?

Predicted earnings for the initial weekend of I Know You Did Last Last Summer 2025 at the box office range between $15 million and $24 million. Over the course of its run within the U.S., total revenues are anticipated to be between $35 million and $64 million.

In my view, I’ve been closely following the box office performance of recent films, and the latest figures I’m referring to are from a July 11 report by Box Office Theory. Interestingly, these numbers show a significant deviation from initial projections made in a late June report. Back then, it was predicted that our film would earn between $19-$28 million for its opening weekend and amass a total of $42-$75 million domestically. However, the current figures suggest a decline of approximately 15-20% on both ends of those projections.

This dip could be attributed to the film not keeping pace with the fast-moving tempo of successful sequels in established horror franchise series like “Final Destination: Bloodlines”, “Scream VI”, and the latest “Halloween” movies. The site has previously discussed this issue in previous reports and is currently monitoring whether there will be increased interest in the film upon its release.

Unfortunately for “I Know What You Did Last Summer” (2025), it finds itself positioned between “Superman” (2025) which hit US screens on July 11 and “The Fantastic Four: First Steps,” nationwide on July 25. In a twist, this fourth film in the series is actually a sequel to the second installment, “I Still Know What You Did Last Summer,” released way back in 1998. Initial plans for the movie were set in motion as early as 2014, but they gained renewed momentum following the cancellation of the 2021 TV adaptation of the series.

As I pen this down, the Rotten Tomatoes rating for the 2025 movie stands at an average 44%. Some reviewers find its self-referential legacy sequel approach appealing, while others feel it falls short and remains unsatisfying.
