I Know What You Did Last Summer (1997) is a defining 1990s teen slasher, following four friends who cover up a hit-and-run accident—only to be stalked a year later by a mysterious hook-wielding killer. With its mix of urban legend horror, Final Girl survival, and glossy teen thriller style, the film became a post-Scream cult hit and launched a franchise.

I Still Know What You Did Last Summer (1998) continues the 90s slasher franchise, with survivor Julie (Jennifer Love Hewitt) lured to a Caribbean island resort where the hook-wielding killer returns. Isolated by storms and cut off from escape, the film amplifies its slasher tropes, Final Girl suspense, and vacation-gone-wrong horror in a tropical setting.

I’ll Always Know What You Did Last Summer (2006) is the direct-to-video continuation of the slasher franchise. After a group of teens accidentally cause a friend’s death during a prank, they swear to keep it secret—only to be hunted by the hook-wielding killer a year later. Leaning into urban legend horror, slasher clichés, and small-town paranoia, the film reimagines the fisherman’s curse for a new generation.
