I Know What You Did Last Summer reboot casts Riverdale and Outer Banks stars

The upcoming I Know What You Did Last Summer reboot has found its cast, according to an exclusive from The Hollywood Reporter.

In addition to Jennifer Love Hewitt and Freddie Prinze Jr., who are in talks to reprise their roles from the 1997 movie as Julie James and Ray Bronson, respectively, the reboot has tapped Riverdale and Outer Banks stars Camila Mendes and Madelyn Cline as its female leads.

Discussions are also underway to cast Tony Award-winning actress Sarah Pidgeon (Stereophonic), Tyriq Withers (Atlanta), and Jonah Hauer-King, who recently starred in Disney's live-action remake of The Little Mermaid alongside Halle Bailey.

No details have emerged about who these actors will be playing, but we can assume Cline and Mendes will play characters loosely inspired by Helen Shivers and Julie James from the original 1997 slasher pic.

Obviously, if Hewitt returns as Julie, Cline and Mendes will be new, original characters that exist in the same universe as those originated by Prinze Jr., Hewitt, Ryan Phillippe, and Sarah Michelle Gellar. Still, I wouldn't be surprised if they shared some likeness with the first film's cast. It would also be interesting if Cline ends up playing Ray and Julie's daughter.

Gellar's character Helen and Phillippe's Barry Cox became victims of Ben Wilkins—The Fisherman—in the 1997 movie, but the fates of Ray and Julie were left up in the air. Ray and Julie got married in the 1998 sequel I Still Know What You Did Last Summer, but the last time we saw them, Ben had suddenly reappeared and yanked Julie under the bed, seemingly to her death.

Hewitt and Prinze Jr. didn't return for the direct-to-video follow-up, I'll Always Know What You Did Last Summer. If they do indeed come back for Sony's legacy sequel, the writers could easily hand-wave the I Still Know What You Did Last Summer ending away as a nightmare sequence.

The new film, which is currently slated to release in theaters on July 18, 2025, will be directed by Do Revenge's Jennifer Kaytin Robinson. She co-wrote the screenplay with Sam Lansky, which itself is based on a script by Leah McKendrick.
