If you're a 90s movies (and horror movies) lover, you might agree that nothing beats an old school slasher. I Know What You Did Last Summer, which stars Jennifer Love Hewitt, Sarah Michelle Gellar, and Freddie Prinze Jr., premiered in 1997, combines everything we love about coming of age movies — friends, summer vacation, and drama — with just enough terror to send a chill down your spine. And just like the original, the new I Know What You Did Last Summer features some of the hottest names in Hollywood.
Everything you need to know about the new I Know What You Did Last Summer sequel movie, coming to theaters July 18, 2025.

This is definitely not a relaxing summer vacation. For instance, Madelyn Cline's guided meditation bubble bath distracting her from the fact her boyfriend's getting murdered by a harpoon & hook? Yikes. The rest of the I Know What You Did Last Summer trailer shows the full crew escaping the mystery man hunting them — and enlisting the help of Ray (Freddie Prinze Jr.) and Julie (Jennifer Love Hewitt).

In the new I Know What You Did Last Summer, five friends accidentally cause a deadly car accident and agree to keep the secret forever. But when someone starts terrorizing them the next year, they reach out to Julie and Ray for help. And Jennifer Love Hewitt can't get enough of this new "phenomenal" cast!
"It's for them to make it their own and for me to stand by like a proud mom and say, 'It's yours now, take it and run and enjoy,'" she told People.
"When you get a group of young actors together, it can be a recipe for disaster oftentimes," Chase Sui Wonders added. "But everyone in this cast just brought it to the nth degree. We all got along so well. The chemistry between us was so fun and natural and seamless."
