I Know What You Did Last Summer (2025) is the highly anticipated sequel to the acclaimed horror film series, set to hit theaters in the United States on July 18, 2025. The film is directed by Jennifer Kaytin Robinson and co-written with Sam Lansky, based on a story by Leah McKendrick. It is the fourth installment in the I Know What You Did Last Summer series and a direct sequel to I Still Know What You Did Last Summer (1998).
The film follows five friends who accidentally cause a fatal car accident and decide to cover it up. A year later, a stranger learns their secret and begins hunting them down one by one in an attempt to get revenge. In their quest to survive, they seek help from two survivors of the 1997 Southport massacre.
In March 2023, Prinze Jr. stated in an interview that he had not been offered the film, explaining, “They just said that to get people excited. I haven’t talked to anyone at their company, my agents haven’t heard from them.” He later claimed that Original Film had announced the sequel without him and that Love had still signed on just to get fans excited, and that he met with Kaytin Robinson after the announcement to discuss his possible involvement. He said that the meeting left him impressed with her ideas for the film but noted that he had not signed on to appear because there was no script yet and he had not received any specific offers. In December, Hewitt stated that she would definitely reprise her leading role.
In May 2024, it was reported that Prinze Jr. and Hewitt were expected to return. In July, Camila Mendes, Madelyn Cline, Sarah Pidgeon, Tyriq Withers, and Jonah Hauer-King were in talks for roles in the film. In August, after previously expressing interest in reprising her role as Karla Wilson from the second film, Brandy Norwood confirmed that she was in talks to do so after the studio contacted her, although she was uncertain about exactly how her character might return. By September, Mendes had left the project due to her starring role 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, Prinze Jr. was confirmed to have been cast, with Hewitt still in talks to return. In October, Billy Campbell was added to the cast. The following month, Lola Tung, Nicholas Alexander Chavez, Austin Nichols, and Gabbriette joined the cast.
In addition, Brandy, who played Karla Wilson in the 1998 film, expressed interest in reprising her role.
