2025’s upcomingI Know What You Did Last Summersequel could fix one major issue with the original movie thanks to a recent slasher trend and its inspired choice of director. 1997’sI Know What You Did Last Summermay have been based on author Lois Duncan’s 1973 novel of the same name, but director Jim Gillespie’s movie had another, more immediately evident inspiration.I Know What You Did Last Summer’s screenplay was written byScreamscribe Kevin Williamson, and the movie shared that classic slasher’s self-aware wit and postmodern style.
Now, 2025’sI Know What You Did Last Summersequelis set to bring the franchise back for a new generation of slasher fans. SinceI Know What You Did Last Summer2025’s cast of charactersincludes Freddie Prinze Jr and Jennifer Love Hewitt reprising their roles from the original movie, the project is a direct sequel set in the same universe rather than a reboot. Like 2022’sScream, 2025’sI Know What You Did Last Summeraims to update the world of the franchise with both returning legacy characters and new stars.
1997’s I Know What You Did Last Summer Isn’t A Whodunit (But It Feels Like One)
I Know What You Did Last Summer’s Original Mystery Is Disappointing
However,Screamhad something thatI Know What You Did Last Summerwas always missing, despite the reliable wit and charm of Williamson’s script. Namely,1997’sI Know What You Did Last Summerisn’t a whodunit mystery, despite how much it might feel like one. Thanks to Kevin Williamson’s writing style,I Know What You Did Last Summerhas the tone and atmosphere ofScream,Urban Legend,Valentine,Cherry Falls, or any other late ‘90s slasher where the killer is not unmasked and identified until the finale. However, this is misleading.

I Know What You Did Last Summer’s killer isn’t Johnny Galecki’s jealous Max, Anne Heche’s unsettling Missy, or any other suspect, but rather Ben Willis, the faceless fisherman the friends accidentally killed in the opening scene. The revelation that he wasn’t really dead retroactively makesI Know What You Did Last Summera more straightforward slasher likeHalloween, rather than a murder mystery.
While this might not seem like a major distinction,I Know What You Did Last Summer’s sequelcan highlight the difference when the movie arrives. Many major slasher franchises, includingFriday the 13th’s sequels, theHalloweenmovies,Child’s Play,Candyman,Leprechaun, andA Nightmare on Elm Street, feature no murder mystery elements since their supernatural villains are easily identified. 2006’sI’ll Always Know What You Did Last Summerattempted this with Ben Willis, reinventing the franchise’s villainous as the explicitly supernatural “Fisherman.”

Ben Willis Is Unlikely To Return By Supernatural Means
However, the disastrous critical failure ofI’ll Always Know What You Did Last Summerproves that viewers preferred the franchise’s original, if misleading, murder mystery tone.

Already,I Know What You Did Last Summer2025’s plotis very similar to the original movie, with another set of kids covering up another tragic accident a generation after their 1997 counterparts did the same. As such, the best way to enliven this potentially predictable story is to reveal that the killer stalking them isn’t the person they thought they killed, but another suspect entirely.
