I Know What You Did Last Summer

I Know What You Did Last Summer is a horror movie in which a group of teenagers go on a road trip and accidentally run over a fisherman in their car. They dispose of the body, thinking he is dead, only to receive a letter the next year stating the film's title. They are then predictably killed off one by one by a man who looks creepily like the one they mowed down. The film was very popular mainly because of it's characters and their subversive attitudes towards what was going on; plot wise it was considered fairly a-typical of teen-slasher films. The film was followed by a sequel, "I Still Know What You Did Last Summer[?]". I starred Jennifer Love Hewitt[?], Sarah Michelle Gellar, Ryan Phillippe, Freddie Prinze, Jr.[?], and Anne Heche[?]. It was written by Kevin Willimson[?] and released in 1997.
