Welcome to the July round of new mystery and thriller adaptations to watch! ‘90s kids are getting a sequel (threequel?) to the horror films I Know What You Did Last Summer and I Still Know What You Did Last Summer. There’s also a generational gap detective duo team and a women-behaving-badly whodunnit! Two are streaming and one is a trip to the theaters with a big bucket of popcorn.

I Know What You Did Last Summer by Lois Duncan

In 1997 and 1998 the slasher thrillers I Know What You Did Last Summer and I Still Know What You Did Last Summer released, starring Jennifer Love Hewitt, Freddie Prinze Jr. Sarah Michelle Gellar, Ryan Phillippe, Brandy, Mekhi Phifer, and Johnny Galecki. The franchise began as an adaptation of Lois Duncan’s same titled novel.

Now (in theaters July 18th), there is a new sequel to those first two films, also named I Know What You Did Last Summer. Once again, a group of teens is involved in a hit-and-run that they cover up, only to find someone coming after them one by one… Jennifer Love Hewitt and Freddie Prinze Jr. return, as the adult versions of their original characters, fully aware that these teens must have done something…
