Our Favourite Trivia:
In September 2014, Sony Pictures revealed plans to remake I Know What You Did Last Summer (1997), with Mike Flanagan and Jeff Howard writing the script. The film was a high priority and was initially set for release in 2016. The project required an estimated budget of $15 to 20 million. Flanagan confirmed that his new iteration of the franchise would be a reboot and not include elements of Lois Duncan's 1973 novel nor of the 1997 feature film. The project was ultimately never made and was subsequently canceled.
In 2019 it was announced that Amazon Studios would develop a television series based on the 1973 novel I Know What You Did Last Summer by Lois Duncan. The series filmed in Oahu, Hawaii in January 2021 and premiered in October 2021. The series cancellation came by January 2022.
This is the first I Know What You Did Last Summer film to actually be released in July. It is also the longest installment in the franchise at 111 minutes.
On an $18 million budget this film made $64.8 million. The domestic opening weekend of $12 million was the weakest performance at the box office in the series, as the first film opened at $15 million and the sequel opened at $16 million. This was also the lowest grossing film in the franchise, compared to the $125 million and $84 million gross of the first and second films respectively.
It took a lot of negotiation between Jennifer Love Hewitt and the studio to get her to return, largely due to a scheduling conflict between the upcoming film and her commitment to the television series 9-1-1.
This is Jennifer Love Hewitt’s third horror movie, the previous 2 being the first 2 installments in the franchise.
Freddie Prinze Jr. says he's "really proud" of his performance and happy with the direction for the character. But he acknowledges the twist is a "big swing" that may prove divisive. At 49 years old, he is also the same age as Muse Watson when he played Ben Willis in the original film.
Sarah Michelle Gellar reprises her role of Helen Shivers from the original film, appearing in Danica's nightmare, in her Croaker Queen attire with her crown. Gellar is digitally de-aged for the cameo, so as to look exactly how she did in 1997. Gellar's involvement in the film had been kept hidden before the film's release.
Brandy Norwood, who was similarly kept hidden before release, reprises her role of Karla Wilson in the mid-credits scene teasing a fifth film.
This is the first film in the franchise where Ben Willis is not the killer, and the first to have a female accomplice.
The film was primarily shot in Australia in October 2024, with locations including Newport Beach, White Bay and Paddington in Sydney. The Eleanor Hotel is really the Oatley Hotel in Oatley, New South Wales, a suburb just outside of Sydney, and the Southport Country Store next door is the neighbouring IGA. Filming continued in Los Angeles in February and March 2025. Last minute shooting took place in June to add a new ending where Madelyn Cline’s character survives (she originally died) and for a short scene in which Cline looked at a framed photo of Sarah Michelle Gellar's legacy character at a grave site.
