Movie Info

Kevin Williamson scripted this thriller, an adaptation of Lois Duncan's novel about four teens involved in a hit-and-run incident. High school senior Julie is driving with friends when their car hits a fisherman. Assuming he's dead, they throw him in the water. Later they panic after an anonymous note arrives. It simply says, "I know what you did last summer." (In Duncan's book, the teens hit a small boy on a bicycle instead of a fisherman.)

    Typical teenage slasher/horror film nothing new and just about watchable.

    I Know What You Did Last Summer is a smart and well-crafted film that helped to revive the teen slasher genre in the late '90s. Based on a novel, the story follows a group of 4 high school graduates who accidentally get into a hit-and-run, and then take a vow of secrecy after dumping the body. The cast is quite good, and includes Jennifer Love Hewitt, Sarah Michelle Gellar, Ryan Phillippe, and Freddie Prinze Jr. Though some of the acting is a bit weak, the storytelling is well done and keeps an air of mystery and suspect throughout the film. Though I Know What You Did Last Summer sticks to the same old tropes of the slasher genre, it does so in a clever and inventive way that's a lot of fun.

    overrated, a lot of elements in the plot did not make sense, was not good enough to be a scare feast. Interesting idea, failed attempt of making it a good piece

    Yawn. So there's a group of teenagers, they kill someone, that someone comes back ... are you bored yet? Yeah me to. The classic mix of screaming beauties, testosterone riddled jocks and slightly outcast plain people running around convincing themselves that anything they do for the 90 minutes this movie lasts matters in the slightest to anyone. One of my least favorite movies ever, and certainly not what one would deem "horror".
