Production
= Development
=Director Jennifer Kaytin Robinson and screenwriter Leah McKendrick came up with an idea for a new installment to the I Know What You Did Last Summer franchise and pitched it to Sony Pictures in the fourth quarter of 2022. The pitch successfully led to the film being put into early development in February 2023, with plans to have producer Neal H. Moritz and stars Jennifer Love Hewitt and Freddie Prinze Jr. return in their respective roles as Julie James and Ray Bronson from the original films. Some days later, Sarah Michelle Gellar told Entertainment Weekly that she had been approached to reprise her role as Helen Shivers from the first I Know What You Did Last Summer (1997) film, owing to her friendship with Robinson, but declined because her character had died in the original film and it would be impossible to retcon her death. The screenplay was written by Robinson and Sam Lansky after McKendrick wrote the initial script. In March 2024, McKendrick revealed that the influence of social media would factor into the film's plot. In July, it was confirmed that the film would continue the story from the second film.
= Casting
=In March 2023, Prinze Jr. said in an interview that he had not received an offer to join the film, explaining "They just said that to get people excited. I haven't spoken to anyone at their company, my agents haven't received an offer from them whatsoever." He later stated that Original Film announced the sequel without him and Love signed on yet just to excite the fans and that he had met with Kaytin Robinson after the announcement to discuss his possible involvement. He said that the meeting left him impressed with her idea for the film but noted that he had not signed on to appear as there was no script and he had received no concrete offer. In December, Hewitt stated that she would definitely reprise her lead role.
In May 2024, it was reported that Prinze Jr. and Hewitt were expected to return. Additional cast members Camila Mendes, Madelyn Cline, Sarah Pidgeon, Tyriq Withers, and Jonah Hauer-King were negotiating roles in the film in July 2024. By September, Mendes had exited the project due to her starring in Amazon MGM Studios' Masters of the Universe (2026), while Cline, Pidgeon, Withers, and King were confirmed to star. Later that month, Chase Sui Wonders joined the cast, and Prinze Jr. was confirmed as having been cast, with Hewitt still in negotiations to return. In October, Billy Campbell was added to the cast. The next month, Lola Tung, Nicholas Alexander Chavez, Austin Nichols and Gabbriette had joined the cast as well.
On December 13, 2024, it was reported that Jennifer Love Hewitt was officially set to return as Julie James.
