The Short Answer
If you searched I Know What Did Last Summer, you almost certainly mean I Know What You Did Last Summer. The phrase is the title of a horror franchise that began with the 1997 slasher film and returned with a new theatrical sequel in 2025. The newer film follows five friends after they cover up a fatal accident. A year later, someone knows their secret and starts hunting them. It is a classic guilt-and-revenge setup, which is why the title still lands so well.

The 2025 movie is not a remake of the 1997 film. It is a legacy sequel, meaning it brings back characters from the original story while introducing a new group in danger. Jennifer Love Hewitt returns as Julie James, and Freddie Prinze Jr. returns as Ray Bronson. That detail matters when deciding whether you need homework first.
Which I Know What You Did Last Summer Movie Is This?
The original I Know What You Did Last Summer arrived in 1997, starring Hewitt, Prinze Jr., Sarah Michelle Gellar and Ryan Phillippe. It turned a coastal-town secret into a glossy late-1990s slasher hit. A sequel, I Still Know What You Did Last Summer, followed in 1998. The 2006 direct-to-video entry I’ll Always Know What You Did Last Summer stands more separately from that first storyline.
The 2025 film, directed by Jennifer Kaytin Robinson, reconnects with the first two movies. Its new cast includes Madelyn Cline, Chase Sui Wonders, Jonah Hauer-King, Tyriq Withers and Sarah Pidgeon. It opened in U.S. theaters on July 18, 2025. People comparing cast returns across revived properties may also want the latest Toy Story 5 cast updates or the He-Man 2026 cast guide.
Do You Need to Watch the 1997 Film First?
Yes, if you want the emotional payoff of Julie and Ray’s return. The 2025 film gives new viewers enough information to follow its main plot, yet it assumes the earlier Southport tragedy carries weight. Watching the 1997 original first makes the connections clearer and preserves a few surprises.
Watch the 1997 movie, then I Still Know What You Did Last Summer, before the 2025 sequel if you want the full thread. The 2006 film is optional. Keep expectations in the slasher lane: masked danger, guilty friends, suspicious townspeople and escalating reveals. If you enjoy comparing a new release with another old-school supernatural follow-up, our Practical Magic 2 reviews and audience reactions cover a very different kind of nostalgia return.
Where Can You Watch It?
Availability changes by country and by subscription service. Sony lists the 2025 film for digital purchase or rental through major storefronts, while streaming access depends on your region and current licensing. Search the full title plus 2025 when checking a service. That avoids landing on the 1997 original, the 2021 television series, or an unrelated fan upload.
For a quick movie-night decision, check whether your preferred store has the rental, purchase and 4K options before paying. That same practical approach helps with recent releases such as where to watch the movie Good Fortune, the movie The Fix streaming guide, and Last Seen on Apple TV viewing details.
Why This Search Keeps Coming Back
The title has a built-in hook. It reads like an accusation before a trailer even starts. The 2025 sequel also arrived when studios were revisiting recognizable horror names, and the original remains a regular Halloween-season pick. toughestblogger readers looking for more October viewing ideas can browse The Whisper Man adaptation details, a Prime Time movie explainer, and Halloween background ideas for a watch party.
