I Know What You Did Last Summer

Hot on the heels of 1996’s genre-redefining Scream, screenwriter Kevin Williamson kept banging out hits, following up with this teen slasher in 1997 before rolling out Dawson’s Creek in 1998. For I Know, he adapted the 1973 novel of the same name by YA author Lois Duncan, and they cast Y2K’s most likable stars for a Fourth of July-set story blending elements of Eighties slashers and the urban legend of the hook man. Fun fact: Co-stars Sarah Michelle Gellar and Freddie Prinze Jr. met on set and later married, and are still adorably together to this day. – Kat McNevins Read a full review of I Know What You Did Last Summer.
