Who is in the I Know What You Did Last Summer 2025 Cast?

The film blends fresh faces with legacy stars. Chase Sui Wonders leads the ensemble as Ava, the central new character returning to her hometown for a bridal shower. Madelyn Cline has been singled out for an outstanding performance, praised by critics as a key strength of the movie. Other newcomers include Jonah Hauer-King, Tyriq Withers (who plays Milo, a victim strangled by the killer), and Sarah Pidgeon as Stevie.

The supporting cast features Danica (the bride-to-be), Wyatt (her fiancé and first victim), Teddy, Grant, Tyler Trevino (a true crime podcaster), Judah Gillespie (town pastor), and Sam (the pedestrian killed in the crash).

Legacy Cast Returns

Freddie Prinze Jr. returns as Ray Bronson, Julie’s ex-husband and Stevie’s boss. He publicly accuses others of covering up the 1997 events during a town hall scene. Reviewers have described his return as a “mixed bag.” Jennifer Love Hewitt reprises her role (her character is implied to be among the 1997 survivors helping the new group). Brandy’s return was teased by the director on April 8, 2025, though her specific role has not been confirmed.

What is the Plot of I Know What You Did Last Summer 2025?

Set in Southport, North Carolina, the story opens on the Fourth of July. Five friends—Ava, Danica, Milo, Stevie, and others—accidentally hit and kill a pedestrian named Sam. They cover up the accident with a pact of silence.

One year later, Ava returns for Danica’s bridal shower, where she meets true crime podcaster Tyler Trevino, who is researching the original Ben Willis killings. Danica receives a chilling note: “I know what you did last summer.” Then the killings begin. Wyatt, the groom, is hacked to death by a hook-wielding figure in a fisherman’s slicker—the same appearance as the deceased Ben Willis.

Who is the Killer in I Know What You Did Last Summer 2025?

The killer is a new Fisherman. Unlike the original, this version is less secretive and more theatrical, described as “hell-bent on revenge” over the friends’ cover-up. The identity is tied to plot elements involving Judah Gillespie and the 1997 legacy. Reviews note “wicked,” “nuts,” and “blood-soaked” kills that are “headline-grabbing.” The killer uses a hook and stalks victims with brutal efficiency—hacking, strangling, and taking bodies. While the exact identity is a mystery, the film deliberately echoes the pattern of the “legendary Southport Massacre of 1997.”

Key plot points include Ray Bronson accusing Grant of covering up 1997 events, the link between Sam’s truck and Pastor Judah Gillespie, and a final confrontation where Ava and Danica are locked up by police after accusing Judah.

Is the 2025 Film a Sequel or a Reboot?

I Know What You Did Last Summer (2025) is a direct legacy sequel. It continues the story from I Still Know What You Did Last Summer (1998), ignoring the 2006 straight-to-DVD entry I’ll Always Know What You Did Last Summer (which turned the Fisherman into a zombie ghost). The 2025 film respects the original timeline by revisiting the 1997 Southport Massacre through returning survivors.

The franchise capitalizes on the legacy-sequel trend seen in Scream (2022) and Halloween (2018), bringing back original stars while introducing a new generation. The film was announced in July 2024 as continuing from the second film.
