Twenty-eight years after the release of I Know What You Did Last Summer, another group of friends are being asked the daunting question: What the heck should we do now that we accidentally killed someone? Of course, the answer isn't "Call the police! What is wrong with you?!" This is a slasher movie we're talking about! The friends have to keep it a secret and attempt to move on with their lives, only to receive mysterious messages from a serial killer a year later. A serial killer who knows what they did last summer.

The new sequel has a similar premise to the first movie from 1997, but it isn't a reboot. Instead, the new group of friends are able to get in touch with two characters who survived the original massacre from the "Fisherman" killer, Julie James and Ray Bronson, with Jennifer Love Hewitt and Freddie Prinze Jr. reprising their roles. (The actors also played the characters in the 1998 sequel, I Still Know What You Did Last Summer, which saw the killer stalk them in the Bahamas.)

But while fans of the original are very familiar with Hewitt and Prinze Jr., there's a bunch of new stars joining in for the new movie. Read on to learn more about them and the characters they're bringing to the big screen.

Madelyn Cline as Danica Richards


Madelyn Cline plays Danica, a member of the friend group who makes a promise not to reveal what happened with the car accident. Fans of Outer Banks will know her for starring as Sarah. She also appears in a couple episodes of Stranger Things and in the movie Glass Onion: A Knives Out Mystery.
