TheI Know What You Did Last Summerreboot loses a lead actor as a keyRiverdalestar drops out. Released in 1997, the original slasher classic follows four friends who are hunted by a hook-wielding killer after a tragic accident. Following two sequels, anI Know What You Did Last Summerrebootis confirmed to be in the works from director Jennifer Kaytin Robinson. Madelyn Cline, Camila Mendes, Sarah Pidgeon, Tyriq Withers, and Jonah Hauer-King were previously reported to comprise the main cast, with original stars Jennifer Love Hewitt and Freddie Prinze Jr. also in talks to return.
Deadlinenow reports thatMendes, who is best known for playing Veronica Lodge onRiverdale, has exited theI Know What You Did Last Summerreboot. The star’s departure is reportedly due to scheduling conflicts with her role as Teela in the upcomingMasters of the Universefilm from Amazon MGM Studios and Mattel Films. There’s no word yet on who will be taking Mendes' role in the upcoming legacy sequel, which serves as a direct sequel to 1998’sI Still Know What You Did Last Summer.
Mendes stars opposite Nicholas Galitzine inMasters of the Universe, which hails from director Travis Knight and is due out in 2026.
Mendes' Character Will Need To Be Recast
TheI Know What You Did Last Summerlegacy sequel is scheduled to hit theaters on July 15, 2025, which is now less than a year away. Filming will presumably be getting underway in the very near future to make this date, meaning the search for Mendes replacement could already be well underway. It’s unclear who Mendes would have played in the film, but the reboot is seemingly following the lead of 2022’sScream, which saw legacy characters and newcomers alike working together to take down a new Ghostface.
I Know What You Did Last Summer Sequel’s Confirmed Timeline Is Facing Two Major Challenges That Can Ruin The Franchise
I Know What You Did Last Summer’s legacy sequel’s place in the timeline has been confirmed, and it creates two major challenges for it.
It’s unlikely at this stage that Mendes' departure will result in a rewrite to the script, with recasting being the most likely option. Robinson previously directed2022’sDo Revenge, which was well-received critically, so the upcomingI Know What You Did Last Summerfilm is certainly in good hands. Mendes actually costarred inDo Revengeopposite Maya Hawke, so the reboot would have marked a reunion for her and Robinson.
Do Revengesports an impressive 85%Rotten Tomatoescritics' score and 78% Popcornmeter score, previously called the audience score.
The Slasher Reboot Still Has Impressive Talent Attached
AfterDo Revenge, a reunion between Mendes and Robinson would have been welcome inI Know What You Did Last Summer. The remaining cast is still strong, however, and Cline has proven herself a strong on-screen talent with projects like2022’sGlass Onion: A Knives Out MysteryandOuter Banks. Hauer-King, too, recently made a splash in Disney’sThe Little Mermaidlive-action remake. While Mendes' departure is definitely a blow to theI Know What You Did Last Summerreboot,the film is still in good hands. This is especially true if Hewitt and Prinze Jr. reprise their roles.
