I Know What You Did Last Summer Movies: Original Trilogy
This watch order follows the original I Know What You Did trilogy released between 1997 and 2006. The first two films center on Julie James (Jennifer Love Hewitt) and Ray Bronson (Freddie Prinze Jr.) as they survive encounters with Ben Willis, the vengeful Fisherman seeking retribution for a hit-and-run.
The 2006 movie I'll Always Know What You Did Last Summer shifts to an entirely new cast in Colorado, though it maintains the Fisherman legend established in the earlier films. While disconnected from Julie and Ray's story, this third entry technically exists within the same universe where the hook-wielding killer's legend continues to claim new victims.
