After weeks of teases, it’s now official: Jennifer Love Hewitt is coming back for the new I Know What You Did Last Summer movie. The actress, an icon of teen movies in the 1990s, confirmed the news on social media with a photo of her staring into a mirror covered with post-it notes of the original movie’s title.
Hewitt is the second cast member from the 1997 horror-thriller to return, following Freddie Prinze Jr. The movie also starred Sarah Michelle Gellar and Ryan Phillippe, centering on four teenage friends who are stalked by a hooked killer who claims to know they covered up a fatal car accident from a year earlier.
The new film is the fourth in the franchise and features newcomers Jonah Hauer-King, Madelyn Cline, Chase Sui Wonders, Sarah Pidgeon, Tyriq Withers, Lola Tung, Austin Nichols, Nicholas Alexander Chavez, and Gabbriette.
Hewitt returns to the role of Julie James, a character created for Lois Duncan’s 1973 novel. Her performance is widely remembered for a few iconic scenes, including the “What are you waiting for, huh?!!!” moment that was parodied in Scary Movie.
Jennifer Kaytin Robinson (Do Revenge) directs from a script co-written with Sam Lansky, Jeff Howard, and Leah McKendrick (Scrambled). The untitled I Know What You Did Last Summer sequel opens July 18th 2025.
