After the success of Scream in the mid-90s, a massive wave of imitators came out that all tried to capitalize on the "teenage slasher" craze in horror movies. The best-known of these was almost definitely I Know What You Did Last Summer, which featured an all-star cast of 90s mainstays, including Jennifer Love Hewitt, Sarah Michelle Gellar, Ryan Phillippe, Freddie Prinze Jr., and Anne Heche.
While the movie feels kind of dated now, we still love it for reasons we can't explain. However, turns out there's a lot of interesting facts behind the making of it, and we're pretty sure even big fans of the movie might not know these 10 things!
It's actually based on a book from the 70s
It's pretty different; the teens actually hit a small child with their car, who (thankfully) doesn't die.
The author of the book absolutely hated the movie
Lois Duncan has been open about her hate of it, complaining that they turned a suspense thriller into a slasher movie. This especially sat poorly with her since her daughter was murdered in 1989.
The script was by the guy who wrote Scream
Kevin Williamson actually wrote the script for I Know What You Did Last Summer before he wrote Scream, but it wasn't picked up for production until after Scream became a huge hit.
The movie is how Sarah Michelle Gellar and Freddie Prinze Jr. met
They hit it off and have been married since 2002! They have two children together.
