Thrillers flood theaters this fall, from whale-gut claustrophobia to AI grief and body horror

A diver swallowed alive by a whale. A streamer who goes to an abandoned hospital to film a prank video and stumbles into a real killing. A mother torn between an AI recreation of her 10-year-old son and the real son who returns after nine years. A ghostwriter who uncovers a hidden manuscript inside a mute author's mansion. A group of job applicants who begin to suspect one another after envelopes containing each other's secrets come to light. A Hollywood actor who regains his face — only to become a monster.

Thrillers are descending on Korean theaters this fall — six films in three weeks. In place of sentimental romance comes what might be called modern suffocation: extreme confinement, the brutality of platform capitalism, and the abyss of humanity eroded by generative AI. Together, the six films translate the fractures of contemporary life into genre tension.

"There's a person inside the whale! Help!"

That cry opens "Whalefall: Swallowed by a Whale," which opens Wednesday. The film wears the skin of a disaster movie but is, at its core, a claustrophobia thriller that squeezes the audience's every physical sense.

The story begins when diver Jay (Austin Abrams) dives into the ocean to recover his father's remains and is sucked inside a sperm whale 24 meters long and weighing 60 tons. Based on Daniel Kraus's source novel, the film's horror does not spring from the unknown deep — it springs from anatomy: the digestive tract itself.

Stomach acid dissolving flesh, water pressure crushing the ribcage as the whale dives deeper, an oxygen gauge needle racing toward zero with 60 minutes on the clock — the film fills its frame with pitch-black darkness to show just how fragile a human being is inside nature's predatory machinery.

Abrams carried that ordeal largely alone. He earned a scuba diving certification and spent 35 days on a set built to replicate the whale's stomach and esophagus. "I wanted to do as much as I could myself to convey the reality of being swallowed by a whale," he said. The whale, however, is not the villain. Director Brian Duffield told the London premiere audience that "Whalefall" is "the opposite of 'Jaws'" and that "in many ways the whale is the main character."

Another countdown — also 60 minutes — ticks on the monitors of an abandoned hospital in "Killing Time," opening Oct. 21. The film fuses a smartphone screen and a live-streaming interface with the classic locked-room setting of a derelict hospital.

The story kicks off when a group of hidden-camera creators, whose careers collapsed after a past on-air incident, switch on a 60-minute live broadcast inside the abandoned hospital in a bid to win back their viewership. The moment masked, unidentified figures appear before the cameras they have set up, the story flips instantly into a survival thriller.

Director Jang Jun-yeop met with reporters Tuesday and said the film is "a work where the tension shines in the moment that manufactured fear becomes a real threat," adding that the title expands from the casual sense of killing time into the idea of a time that kills. The film holds up a mirror to a reality in which internet broadcasts consumed as snack content can, when fused with capitalism's algorithms, become a brutal spectacle that puts human lives on the line.

Actor Ryu Hye-young, who plays streamer Yeon-woo returning to the camera burdened by guilt, said the script "read in one breath from start to finish without a single pause" and expressed an intense desire to work in the genre.

A different clock is ticking for job applicants — set for two hours, the length of the interview. "Final Interview," opening Nov. 4, follows six candidates who have beaten 5,000-to-1 odds for a single position.

Director Kim Jeong-hun explained that "the final candidate is determined through a two-hour group discussion and five rounds of voting." When envelopes containing each applicant's secrets are discovered, the game turns upside down. In the trailer, Hye-in (Jo Yi-hyun) warns the other candidates: "You're next." The film also stars Kim Jae-won, Shin Seung-ho, Kang Yu-seok, Kwak Dong-yeon and Bae Gang-hee.

So-young (Kim Hyun-joo) lost her son in a bus disappearance nine years ago. An AI program offers grieving parents a virtual recreation of their missing children — and her son still speaks to her as a 10-year-old. Then one day, her son Seon-woo (Bae Hyeon-seong), whom she had believed dead, comes home alive. His body is covered in scars and his eyes feel like a stranger's. With her grown son in the next room, So-young puts on special glasses and meets the AI's 10-year-old version of him again. That is the premise of director Yeon Sang-ho's "Paradise Lost," opening Oct. 21 — a film that stares into the grotesque psychological collapse that technology can produce.

"Paradise Lost" began with three pages his mother had written in a notebook. At a recent press conference, Yeon said he wrote the screenplay "out of curiosity about the psychology of a wicked son and a mother who loves that son unconditionally, and a desire to explore it."

He went on to say: "Contemplation is a world that does not exist for artificial intelligence. It is through human contemplation that suffering, joy and everything else arise — that, I believe, is what makes us human. I think the unsolvable space of contemplation in the universe is the human abyss, and I tried to tell the story in that spirit."

The film was made on a production budget of about 500 million won ($375,000), shot over 14 days. It is Yeon's follow-up to "Face," which he made last year for about 200 million won, and had its world premiere at the Toronto International Film Festival last month. Yeon also used generative AI to expand the "Paradise Lost" universe, producing four short films in just two weeks.

"Verity," starring Anne Hathaway and opening Oct. 22, topped the North American box office in its opening weekend. Its secrets lie buried in a manuscript. Bestselling author Verity (Hathaway) has been left unable to walk or speak after an accident. Ghostwriter Lowen (Dakota Johnson) moves into Verity's sprawling mansion to finish the novel she could not complete — and there discovers an autobiography Verity wrote herself. With each page, the secrets of Verity and her husband Jeremy (Josh Hartnett) surface one by one. The film is based on Colleen Hoover's novel of the same name. In North America, it earned $32.6 million over its opening weekend of Oct. 2–4.

Rising Hollywood actor Matt Hagen (Tom Rhys Harries) has his face destroyed in an attack by a crime boss, then regains it through experimental treatment — at a steep price. His body twists like clay, turning him into a monster, and his revenge begins. That is "Clayface," opening Oct. 21.

The film is DC Studios' first horror movie, built around a villain from the "Batman" franchise, and the first in the new DC Universe to receive a US R rating (requiring parental accompaniment for viewers under 17). It is directed by James Watkins of "Speak No Evil" and written in part by Mike Flanagan of "Doctor Sleep." Producer Peter Safran described the film as "David Cronenberg-style body horror" — a genre in which fear is generated by a body transforming or falling apart.
