How many I Know What You Did Last Summer movies are there?
It all started with a note—a novel, actually—all the way back in 1973 with Lois Duncan’s book I Know What You Did Last Summer (Little, Brown) about four North Carolina teens who accidentally hit and kill a young boy, covering up the crime, only to get mysterious, anonymous notes from someone with knowledge of their misdeed.
Nearly a quarter-century later, the film adaptation popped up, with a cast led by ‘90s stars Jennifer Love Hewitt, Sarah Michelle Gellar, Freddie Prinze Jr., and Ryan Phillippe, and a retooled script by Kevin Williamson (Scream) that reimagined the story as a slasher film. Three sequels—including this year’s legacy sequel with the same title—and a one-season-and-done TV series followed the original movie.

List of I Know What You Did Last Summer movies in order
Where to watch I Know What You Did Last Summer (1997)
Kevin Williamson’s script took Duncan’s idea and cranked it up to peak ’90s slasher mode. It had everything: teen idols fresh off TV hits, a seaside town dripping with atmosphere, and The Fisherman, a killer in a rain slicker who haunted an entire generation’s nightmares. Oh, and who could forget Jennifer Love Hewitt screaming at the sky—an image that’s been GIF’d a million times since. It’s glossy, campy, and exactly what horror fans wanted at the time (something Scream-y).

Where to watch I Still Know What You Did Last Summer (1998)
Sequels rarely wasted time in the ’90s, and this one came out barely a year after the original. Julie and Ray (Hewitt and Prinze, Jr.) win a vacation to the Bahamas (via a radio contest twist that fans still joke about), and of course, The Fisherman crashes the trip. Between tropical storms, creepy karaoke, and pop star Brandy holding her own against the killer, it’s pure late-’90s horror excess. Critics rolled their eyes, but horror fans still revisit it as a fun, guilty pleasure watch (that earned roughly $84 million globally).

Where to watch I’ll Always Know What You Did Last Summer (2006)
Straight-to-DVD slashers usually mean one thing: new cast, new town, and a much smaller budget. This time, the story shifts to Colorado, where a prank with a fake Fisherman turns deadly. A year later, the “legend” bites back—or maybe it’s something else entirely. It’s not polished like the originals, but for franchise completists, it’s a weird little relic of mid-2000s horror.

Where to watch I Know What You Did Last Summer TV Series (2021)
Amazon’s streaming-era reboot gave the franchise a glossy Gen Z makeover. Set in Hawaii, the series leaned into a darker, bloodier version of the familiar story—graduation night ends in tragedy, secrets pile up, and the killings begin. It only lasted a single eight-episode season, but it kept fans talking with shocking twists, brutal deaths, and wild theories about the Fisherman’s identity.

Where to watch I Know What You Did Last Summer (2025)
Nearly three decades (27 years to be precise) after the first movie, the Fisherman is back—and so are Jennifer Love Hewitt and Freddie Prinze Jr. This legacy sequel mixes fresh blood with familiar faces, leaning into nostalgia while setting up a new round of deadly secrets. Fans of the originals get callbacks, newcomers get jump scares, and everyone gets another reminder that you can’t hide a cover-up forever. Critics hated it, but it still made four times its budget at the box office.
