I Know What You Did Last Summer sequel: Release date, plot theories, & more

The cult classic I Know What You Did Last Summer is getting a sequel, and a release date has been announced.

The 1990s were known for tie-dye, dead Tamagachis, and the advent of the internet, but they were also defined by slasher horror movies.

Bolstered by the meta Scream movies, the decade revisited classic franchises like Friday the 13th, Nightmare on Elm Street, and Chucky, as well as new movies like I Know What You Did Last Summer.

Following the success of recent reboots, I Know What You Did Last Summer is returning from the dead.

I Know What You Did Last Summer sequel release date

The new I Know What You Did Last Summer sequel will be released in theaters on July 18, 2025.

Sony confirmed the new movie will be directed by Jennifer Kaytin Robinson (who made the brilliant Netflix teen movie Do Revenge). She and writer Leah McKendrick pitched the idea for a revival of the series to Sony in 2022

Reportedly, this decision was spurred by the success of Scream 5 and the upcoming Scream 6. The franchise was halfheartedly revived previously, for the now-cancelled Prime Video series.

Who could be in the I Know What You Did Last Summer sequel cast?

No official casting announcements have been made. However, Deadline reported that original final girl Jennifer Love Hewitt and Freddie Prinze Jr. are in talks with Sony to reprise their roles.

Unfortunately, Sarah Michelle Gellar’s character was offed in the original. So, no romantic Daphne and Fred reunion this time round (Prinze Jr. and Gellar are married).

Like other horror reboots, we’d expect a healthy mix of legacy characters and fresh faces.

What could the I Know What You Did Last Summer sequel plot be?

Like all I Know What You Did Last Summer movies, the 2025 sequel will almost certainly be about a group of characters being blackmailed and killed off for a sin they committed.

The conceit is rather cynical, in retrospect. The original story concept seems to have a punitive slant weaponized against those pesky 90s youths. In the first and second films, the group was threatened by a killer who wanted to punish them for what they got away with.

The original movie followed a group of four teenagers after they accidentally killed a fisherman in a car accident and then hid the body. The group reunited one year after the accident and was terrorized by a mysterious killer with a hook for a hand.

In the second, it was a bit more complicated with no obvious new crime taking place, but it all tied back together eventually.

Plot details are under wraps, as is the full cast list, but they’ll soon follow.
