The series is a new take on Lois Duncan's 1973 novel and has nothing to do with the films. It is set in Wai Huna, a small town in Hawaii. Twins Lennon and…
Explore I Know What You Did Last SummerIt started with a book. Lois Duncan published I Know What You Did Last Summer with Little, Brown in October 1973. Four high school seniors in Silver Springs, New Mexico, near Cibola National Forest, hit and kill a boy on a bicycle while driving home from a party in the mountains. Ray calls an ambulance from a pay phone without giving his name, and the four swear never to tell. A year later Julie James gets a note that says "I know what you did last summer." The stalker turns out to be Collie Wilson, the dead boy's older brother, a war veteran who calls himself Bud. Nobody dies in the present-day story. Barry is shot, Helen is attacked in her apartment, and Ray saves Julie at the end.
The novel sold for decades as a teen thriller. The 1997 movie tie-in edition sold 517,000 copies by November 1998 and topped the Publishers Weekly children's fiction bestseller list for October, November and December 1997. A 1999 Dell paperback made the American Library Association's 2005 Popular Paperbacks for Young Adults list. In 2010 Duncan updated the book for a paperback reissue on October 5, 2010. She added cell phones and newer clothes, moved Collie's war service from Vietnam to Iraq, and renamed the victim from David to Daniel.
Duncan's own life gave the story a hard edge later on. Her youngest daughter, Kaitlyn Arquette, was shot to death in Albuquerque on July 16, 1989, at age 18. Duncan wrote about her own investigation in Who Killed My Daughter? (Delacorte, 1992) and moved away from suspense writing. That is a big part of why she hated the 1997 film. In a 2002 interview she said she was appalled her book had been turned into a slasher film, and that as the mother of a murdered child she did not find violent death something to squeal and giggle about. She did not promote the movie. Duncan won the Margaret A. Edwards Award in 1992 and was named a Mystery Writers of America Grand Master in 2014. She died in Bradenton, Florida, on June 15, 2016, at 82.
The film series came out of the mid 1990s slasher comeback. Producer Erik Feig pitched a film of the novel to Mandalay Entertainment, the company Peter Guber founded in 1994 with an exclusive deal at Sony. Feig brought in Kevin Williamson to rewrite it. Williamson's script sat on the shelf until Scream, his other script, became a hit in December 1996. Columbia then rushed I Know What You Did Last Summer into production. Williamson moved the story to a North Carolina fishing town and made the killer a fisherman with a hook. He has said the idea came from his father, who was a commercial fisherman. Where Scream joked about horror movies, this one played it straight, like an early 1980s slasher.
Scottish director Jim Gillespie shot the film in ten weeks starting March 31, 1997, mostly at night, in and around Southport, North Carolina, with the crash scene filmed on Highway 1 in Sonoma County, California. Jennifer Love Hewitt played Julie James, Freddie Prinze Jr. played Ray Bronson, Sarah Michelle Gellar played Helen Shivers and Ryan Phillippe played Barry Cox. Muse Watson played the killer, a grieving fisherman named Ben Willis. Columbia opened it October 17, 1997. It debuted at number one with $15,818,645, stayed on top for three weekends including Halloween, and finished with about $72.6 million in the United States and Canada and about $125.6 million worldwide on a $17 million budget.
Columbia wanted a sequel fast. Director Mike Mendez pitched a college-set follow-up in 1997 that went nowhere. Mandalay hired Trey Callaway, and separately hired Stephen Gaghan to write a New Orleans version. Callaway's script won. British director Danny Cannon made I Still Know What You Did Last Summer in Mexico and Los Angeles in the spring of 1998, and Columbia released it November 13, 1998, only 13 months after the first film. Hewitt, Prinze Jr. and Watson came back. Brandy, Mekhi Phifer, Matthew Settle, Jennifer Esposito, Bill Cobbs, Jeffrey Combs, John Hawkes and an uncredited Jack Black joined them at a Bahamas resort called Tower Bay. It opened second behind The Waterboy with $16.5 million and made about $40 million at home. Variety later put its worldwide total at $84 million. Critics were far harsher on it, and Gillespie later said it hurt the franchise.
A third film took eight years. In August 2000 Variety reported Columbia was developing one written by Simon Barry about a group on an Outward Bound style wilderness trip. That version was dropped. In July 2005 Sony moved ahead with a script by Michael D. Weiss under the working title I Know What You Did Last Summer 3. The first director was let go right before shooting, and Sylvain White took over with about two weeks to prepare. The film shot in Utah and went straight to DVD from Sony Pictures Home Entertainment on August 15, 2006, as I'll Always Know What You Did Last Summer. It had no returning actors. Stuntman Don Shanks played the Fisherman, and the film revealed him to be an undead Ben Willis. It has a 0 percent score on Rotten Tomatoes.
For years after that the series was quiet. In September 2014 Sony announced a remake written by Mike Flanagan and Jeff Howard, with Flanagan saying it would be a reboot that used nothing from the novel or the 1997 film. It was budgeted at $15 to $20 million and was never made. The first two films stayed in print on home video. Sony put the original on Blu-ray in 2008 and the sequel in 2009, Mill Creek licensed budget and SteelBook discs, and 88 Films in the United Kingdom released all three films as a limited Blu-ray trilogy set in December 2020.
Television came next. Amazon Studios announced a series on July 26, 2019, with Neal H. Moritz producing and Shay Hatten writing. Amazon ordered it straight to series on October 14, 2020, with Sara Goodman as showrunner and James Wan's Atomic Monster and Sony Pictures Television Studios on board. It shot on Oahu starting January 25, 2021, and premiered on Prime Video on October 15, 2021. The show was a new take on the book with no tie to the films. It moved the story to a fictional Hawaiian town called Wai Huna and built it around identical twins played by Madison Iseman. Reviews were mixed to negative, and Amazon canceled it on January 7, 2022. Goodman said people just did not watch it.
After the show ended, Jennifer Kaytin Robinson and Leah McKendrick pitched Sony a new sequel late in 2022. Deadline and Variety reported it in February 2023, tying it to the success of the Scream revival. Sony confirmed in July 2024 that it would follow the 1998 film. Freddie Prinze Jr. signed on in September 2024, and Hewitt announced her return in December 2024. The new film shot in Sydney, Australia, from October 2024 and in Los Angeles through March 13, 2025, with a new ending shot in June 2025 after test screenings. Sony released I Know What You Did Last Summer on July 18, 2025. Chase Sui Wonders, Madelyn Cline, Sarah Pidgeon, Tyriq Withers and Jonah Hauer-King played a new group of friends in Southport. Gellar appeared as Helen in a nightmare, and Brandy returned as Karla in a mid-credits scene.
The 2025 film made money but not much. It opened third with $12,755,359 and finished with $32,165,634 in the United States and Canada. Box Office Mojo now lists $64,808,120 worldwide, with $32,642,486 from other countries led by the United Kingdom, France and Mexico, and The Numbers lists $63,354,791, on an $18 million budget. Rotten Tomatoes scored it 36 percent and CinemaScore audiences gave it a C+. Fans split over the twist that Ray Bronson was one of the killers. It came out on digital August 26, 2025, on disc October 7, 2025, and streamed on Netflix from October 16, 2025, under Sony's first window deal.
Where the franchise stands in 2026: it is four films, one canceled season of television and one novel. Every film has been a Sony release, and Neal H. Moritz is the one producer who has worked on every film and the series. The 2025 film ends with Julie getting a note that says "it isn't over" and going to see Karla, which sets up another film. Stevie Ward's body was never found either. On February 24, 2026, Scream Horror Magazine reported, citing an unnamed source, that Sony was developing a direct sequel to the 2025 film. It said Sony wanted Hewitt back as Julie in a bigger part and that Brandy was in talks to co-lead as Karla, with the two hunting a killer who goes after their families and taunts them about what they survived in 1998. The report said Robinson was unlikely to return. Sony had not announced the film as of September 2026. The Fisherman also turned up in Call of Duty: Black Ops 6 and Warzone during Season 05 in August 2025.
The home video side stays busy. The original film has been on 4K since its 25th anniversary disc on September 27, 2022, the sequel since September 26, 2023, and the 2025 film since October 7, 2025. The 2006 film got its first United States Blu-ray on September 26, 2023. The 2021 series has never had a physical release and remains on Prime Video.
Real life caught up with the book's author too late for her to see it. Kaitlyn Arquette's killing went unsolved for more than 30 years. In July 2021 Paul Apodaca was picked up by University of New Mexico police on a probation violation and confessed to her murder and two others from 1988 and 1989. He pleaded guilty on January 25, 2024, to three counts of second degree murder plus attempted rape and kidnapping, and was sentenced to 45 years in prison. Duncan had died in 2016 without knowing who killed her daughter.
Every version starts the same way. A group of young people causes a death on the road, hides it, and swears never to talk. A year later someone sends the words "I know what you did last summer." The book, the films and the series all keep that setup. What changes is who the victim was and who is doing the knowing. In the novel it is a boy on a bike and his brother. In the films it is a fisherman who survived. In 2006 it is a friend killed in a prank. In the series it is one twin killed and the other taking her place. In 2025 it is a truck driver, and the avengers are his friend and a survivor of the first film.
The Fisherman is the films' icon. He wears a full length oilskin slicker with a deep hood and carries a steel hook. Kevin Williamson tied the hook to the campfire scene in 1997, where the friends tell the old Hook legend, so the film could say here is the old legend, now here is a new one. Later entries add weapons. Will Benson uses a harpoon in 1998, and the 2025 Fisherman uses a speargun. The series swaps the note for a severed goat head left with a message.
The Fourth of July is the franchise's clock. The 1997 accident happens on July 4, 1996, and the killings come during the next Fourth of July weekend, around the Croaker Queen pageant and parade. The 2006 prank happens on July 4, 2005. The 2025 crash happens on July 4, 2024. The series moves the night to graduation.
Ben Willis has the fullest backstory. His daughter Susie died in a crash while David Egan was driving. He killed Egan and made it look like suicide, and his fake suicide note is the handwriting clue Julie finds. The 1998 film adds a wife, Sarah, found murdered years before, and a son, Will Benson, who helps him. So Willis was already a killer before the friends ever hit him.
The films split into branches. The main line is the 1997 film, the 1998 film and the 2025 film. The 2025 film says the Bahamas murders happened, calls them the Tower Bay murders, and picks up 27 years later. Director Jennifer Kaytin Robinson told Entertainment Weekly that the last-minute scares at the end of the first two films are not canon. That means the shower attack in Boston and the under-the-bed attack are nightmares, which is how Julie and Ray are alive.
The 2006 film is its own branch. It follows the first two films, mentions the Southport murders eight years earlier, and brings Ben Willis back as an undead killer who can be hurt by a hook. The 2025 film ignores it. It is the only film set inland and the only one to make the killer supernatural.
The 2021 series is a third branch. It adapts the novel fresh, has no link to the films, and adds a cult, a twin switch and a Hawaiian setting. Sara Goodman's series bible set out the killer and the deaths from the start. The canceled second season would have explained more of the cult.
The canceled 2014 Flanagan and Howard remake would have been a fourth branch. Flanagan said it would use nothing from the 1973 novel or the 1997 film.
Inside the main line, the in-story dates run like this. July 4, 1996: the accident on the coast road. July 1997: the Southport murders, with Max, Barry, Helen, Elsa and Officer Caporizo killed. Summer 1998: the Tower Bay murders in the Bahamas, where Willis dies. July 4, 2024: the Reaper's Curve crash. Summer 2025: the new Southport murders, where Ray dies and Stevie's fate is left open. The 2025 film also shows that Southport buried the 1997 murders to protect its tourist trade, which is part of Ray's motive.
The novel runs on different rules from the films. Its town is Silver Springs, New Mexico, Helen's last name is Rivers, the victim is David Gregg, and the stalker is his brother Collie. Nobody dies in the present day story. The 2010 revision changed David's name to Daniel and made Collie an Iraq War veteran instead of a Vietnam veteran.
Karla Wilson is the franchise's other thread. She survives 1998, and the 2025 mid-credits scene has Julie bring her a note that says "it isn't over" with a photo from the Bahamas. Stevie Ward's body was never found. Those two loose ends are where the story was left.

The three theatrical films cost a combined $59 million. Using Box Office Mojo for the first and fourth films and Variety's $84 million for the second, they grossed about $274.4 million worldwide ($125,586,134 plus $84,000,000 plus $64,808,120), close to the $274.3 million Wikipedia gives for the franchise. Domestic totals come to $144,753,880 using Box Office Mojo's figures. The Numbers' franchise page lists $144,436,347 domestic and $228,625,504 worldwide, but it counts no foreign money for the 1998 film and lists the 2025 film with a wrong June 19, 2025 date. Combined opening weekends were $45,094,042 per The Numbers. In the United States and Canada the first film alone out-grossed the second and fourth films combined.
The films began at Mandalay. Peter Guber, a former head of Sony Pictures Entertainment, founded Mandalay Pictures on September 30, 1994, with an exclusive film and television deal at Sony, releasing through Columbia and TriStar. Producer Erik Feig pitched the Lois Duncan novel to Mandalay Entertainment, and Neal H. Moritz's Original Film came in as producer. Original Film was founded in 1990 by Moritz and Bruce Mellon and had a distribution partnership with Sony from 1997 to 2019. Columbia Pictures released both 1990s films through Sony Pictures Releasing.
Mandalay's film division moved from Sony to Paramount in 1998 and later to Universal in 2002, while Mandalay Television stayed with Columbia TriStar Television. The IKWYDLS films stayed at Sony. The 1998 sequel's copyright was registered to Global Entertainment Productions GmbH & Co. Medien KG, and the AFI Catalog lists it as a United States, Mexico and Germany co-production.
The first film's ad campaign led to a lawsuit. Columbia and Mandalay advertised it as "From the creator of Scream," meaning Williamson. Miramax, which released Scream through Dimension, sued and argued the line made people think Wes Craven was involved. Williamson had already asked for the line to come down. The week after release a federal judge granted Miramax an injunction ordering it removed. Miramax won again at a hearing in March 1998, and Bob Weinstein said the company would pursue damages against Columbia.
The 2006 film was a home video product. Sony moved the project ahead in July 2005, weighed a theatrical run and sent it straight to DVD through Sony Pictures Home Entertainment. It is credited to Destination Films, Original Film and Mandalay Pictures.
In September 2014 Sony announced a $15 to $20 million remake with Mike Flanagan and Jeff Howard writing. It was canceled.
Television went through Amazon. Amazon Studios announced the series on July 26, 2019, and ordered it on October 14, 2020. It was made by Amazon Studios and Sony Pictures Television Studios with Off Center, Original Film, Mandalay Television and James Wan's Atomic Monster. Original Film had signed a Sony Pictures Television deal in 2015 and hired Pavun Shetty to run its TV division. Amazon canceled the show on January 7, 2022. It remains a Prime Video exclusive with no disc release.
The 2025 film is a Columbia Pictures, Screen Gems and Original Film production released by Sony Pictures Releasing. Original Film's own feature deal had moved to Paramount starting in 2019 and was renewed through 2027 in April 2024, but Moritz still produced this Sony title. Sony put it on digital August 26, 2025, and on disc October 7, 2025, and it went to Netflix on October 16, 2025, under Sony's first window streaming deal.
Home video rights have been spread around. Columbia TriStar Home Video released the first VHS and DVD editions. Sony Pictures Home Entertainment made the Blu-rays and 4K discs. Mill Creek Entertainment licensed a 2014 budget Blu-ray and a 2024 Walmart SteelBook of the first film. 88 Films licensed all three films for a United Kingdom trilogy set in December 2020.
The Indian film Kucch To Hai (2003), directed by Anurag Basu and Anil V. Kumar, has been called an unofficial remake of the first film. Its star Tusshar Kapoor said the idea came from the American film but was adapted for India. No licensing deal has been reported.
The Fisherman has been licensed to video games. Activision added him as a playable operator in Call of Duty: Black Ops 6 and Call of Duty: Warzone during Season 05 in 2025.
The Kaitlyn Arquette case was finally closed in court. Paul Apodaca pleaded guilty on January 25, 2024, and got 45 years. It has no legal tie to the book or films, but it is part of why Lois Duncan turned against the 1997 adaptation, and it ended the long search she described in Who Killed My Daughter?.
The first film was a commercial hit and a critical shrug. It spent three weekends at number one. Rotten Tomatoes has it at 47 percent, Metacritic at 52, and CinemaScore audiences gave it a B minus. Roger Ebert gave it one star and wrote that the best shot in the film is the first one. Derek Elley in Variety called it a polished genre piece, and Richard Harrington in The Washington Post liked it better than Scream. Leonard Maltin gave it two stars but said it looked like a classic next to the sequel.
Lois Duncan was the film's harshest critic. She disliked seeing her book turned into a slasher and, as the mother of a murdered child, did not find violent death something to squeal and giggle about. The film still made the book a bestseller again, with the tie-in edition selling 517,000 copies.
The first film helped launch its cast. Kevin Williamson's Wikipedia entry credits it with launching the careers of Hewitt, Prinze Jr., Gellar and Phillippe. Gellar and Prinze Jr. met on it and married in 2002. Scholar Adam Rockoff called it a throwback to early 1980s slashers, and James Berardinelli credited it and Scream with starting a new slasher boom.
The sequel did worse on every count. Rotten Tomatoes has it at 10 percent with a consensus calling it the kind of rehash that gives horror sequels a bad name. Metacritic gives it 21. Audiences were a little kinder, with a CinemaScore of B. Jim Gillespie said it was not the right story and killed the franchise a little bit. Over time fans have held on to some of it, especially Jack Black's uncredited pool boy, the tanning bed scene and Brandy's Karla, who lives because the actor had it written into her contract.
The 2006 film is the franchise's low point with critics. It has 0 percent on Rotten Tomatoes from seven reviews. DVD Talk called it witless and scare-free. Fangoria's Michael Gingold praised its photography and the gondola attack but said the supernatural twist threw away the mystery. Later write-ups at Bloody Disgusting have given it a little credit for trying something new.
The 2021 series drew mixed to negative reviews. Rotten Tomatoes has it at 41 percent, calling it a bloodless slasher full of plot holes, and Metacritic gave it 45. Variety's LaToya Ferguson said it would have worked better as a movie, while Bloody Disgusting praised the kills and Screen Rant singled out Brianne Tju as a next generation scream queen. Showrunner Sara Goodman blamed early backlash over it not being the movie for keeping viewers away.
The 2025 film got mostly negative reviews. Rotten Tomatoes has it at 36 percent, with a consensus saying it serves up nostalgia without a hook of its own. Metacritic scored it 42 and CinemaScore audiences gave it a C+. IndieWire gave it a B+, Entertainment Weekly a B minus with praise for Madelyn Cline, and RogerEbert.com one star. The Ray Bronson twist split fans. Robinson called it a deliberate swing and said films people argue about on the ride home are a good thing.
The franchise became a parody target almost right away. Scary Movie in 2000 built its backstory on a hit and run after a beauty pageant, with Buffy Gilmore spoofing Helen, and grossed $278 million worldwide. Shriek If You Know What I Did Last Friday the 13th spoofed it the same year. Its title turned up in television episode names, and it reached other films as far away as India, where Kucch To Hai (2003) was called an unofficial remake.
Its influence runs into Scream too. SlashFilm pointed out that two scenes Gillespie cut from the first film, the killer fighting Helen inside the police car and Helen throwing things while running up the stairs, turned up in Scream 2. The dock set built for the first film shared space with Williamson's Dawson's Creek, which later spoofed the film in its episode "The Scare."
Home video keeps it alive. The first film has had a 25th anniversary 4K, several SteelBooks and a UK trilogy box set, and its 2025 4K SteelBook came out ahead of the new film. Muse Watson has recorded interviews for both 4K discs, and Gillespie, Danny Cannon and Sylvain White have all recorded commentaries.
Julie James has become a topic of her own. Wikipedia now has a page just for the character. For years critics such as Trace Thurman argued she was a weak final girl and that Helen should have lived. Others pushed back, and in 2025 writer Josh Korngut made the case that she belongs in the conversation with Laurie Strode and Sidney Prescott. The 2025 film made her a professor who teaches about trauma, and Hewitt said Julie had carried hers for decades.
The 2025 film ended up the lowest grossing theatrical entry. Its $12.8 million opening was below the first film's $15.8 million and the sequel's $16.5 million. Even so, its low budget kept sequel talk alive, and a February 2026 report said Sony was building the next film around Hewitt and Brandy. Sony has not confirmed it.
The best-known fan project is I Know What You Did Last Summer: The Unauthorized Musical. It premiered at El Cid in Los Angeles in 2018 with Greer Grammer as Helen and Bianca Gisselle as Julie. Organizers called that first run a sellout, and it returned to The Three Clubs in Hollywood from June 7 to July 13, 2019. Jordan Ross, who had already done the same for Cruel Intentions, adapted and directed it, and Matt Shively and Trent Mills alternated in the slicker. Tickets came with a two item minimum, and the VIP ticket came with a shot.
The fan argument that never ends is Helen against Julie. Trace Thurman at Bloody Disgusting wrote in 2017 that Julie is a terrible final girl and that Helen is the deeper, more likable character who should have carried the film. WhatCulture made the same case in 2020. Others defend Julie. SlashFilm called her resourceful and a realistic survivor, and Decider crowned Hewitt the true queen of scream. In the 2025 film, Gellar came back as Helen in a dream sequence, wearing a copy of the Croaker Queen dress.
The film lives on in podcasts. Horror and nostalgia shows keep going back to it: F This Movie!, The Terror Table, Debt to Cinema, Slaughter Film, Back in Time, Cherish or Perish (which gave the soundtrack its own segment), Cocktail Party Massacre (which invented a drink for it) and The Bechdel Cast. The Faculty of Horror recorded a fan commentary track for I Still Know, and The Hysteria Continues recorded official ones for 88 Films.
Fans were making things for these films from the start. Windows desktop themes for the first film (dated April 9, 1998) and the sequel (February 17, 2000) were passed around on theme sites and Tucows, and copies survive in the Internet Archive. Fan fiction continuations of I'll Always Know, fan-made DVD openings for the 2025 film, and even a 2017 Wings of Fire fan animatic titled I Know What You Did Last Summer have ended up in the same archive.
Parody is a fandom of its own here. Scary Movie (2000) took its central plot from this film and Scream, with Anna Faris's Cindy Campbell based on Julie and Sidney. Shriek If You Know What I Did Last Friday the Thirteenth came out the same year. The Simpsons did "I Know What You Diddily-Iddily-Did" in Treehouse of Horror X in 1999. Boy Meets World's "And Then There Was Shawn" put Hewitt herself in a parody of her street scream. Dawson's Creek spoofed it in "The Scare" (May 5, 1998), and Popular did "I Know What You Did Last Spring Break." Supernatural, The Vampire Diaries and MTV's Scream all named episodes after it. The new Scary Movie, which opened June 5, 2026, went after the franchise again.
Outside America the formula was copied, sometimes closely. In India, Kucch To Hai (January 24, 2003, directed by Anurag Basu and Anil V. Kumar, starring Tusshar Kapoor and Esha Deol) took its idea from the 1997 film. Kapoor said it was adapted to Indian traditions, and Taran Adarsh at Bollywood Hungama called it a poor copy anyway. South Korea's The Record (2000) has also been called a Korean take on it, and Bloody Disgusting covered both films in a July 2025 piece on international copycats.
