In short: Cobweb is a 2023 American horror-thriller directed by Samuel Bodin, starring Lizzy Caplan and Antony Starr as the overprotective parents of a bullied eight-year-old boy who hears mysterious tapping from inside his bedroom wall. The film blends creepy, Halloween-set atmosphere with a dark family-secret twist, and it’s worth knowing there’s a completely unrelated South Korean film sharing the exact same title.
What Is the Cobweb Movie About?
The story follows Peter, a shy, bullied eight-year-old living with his emotionally distant parents, Carol and Mark. He begins hearing a constant, unsettling tapping sound coming from inside his bedroom wall, but his parents insist it’s nothing but his imagination.
As Peter’s fear grows, he starts to suspect his parents are hiding something far more sinister than a simple noise complaint. The film leans into a slow-building sense of dread rather than jump scares, with a pumpkin-filled, Halloween-week setting giving it a distinctly autumnal horror atmosphere.
Cobweb Movie Cast
Lizzy Caplan plays Carol, Peter’s mother, delivering a performance that shifts between warmth and something noticeably unsettling as the film progresses. Antony Starr, known for his role in The Boys, plays Mark, Peter’s father, rounding out a household that feels increasingly claustrophobic as the story unfolds.
Woody Norman stars as Peter, carrying much of the film’s emotional weight as a child caught between fear and disbelief. Cleopatra Coleman plays Miss Devine, Peter’s substitute teacher, who becomes one of the few adults in his life who takes his fears seriously.
Cobweb Movie Plot Summary (Spoiler-Free)
Peter’s isolation at school and at home sets the stage early, establishing him as a boy nobody quite believes. The tapping in his wall escalates alongside his parents’ increasingly strange, overprotective behavior, and small details throughout the house hint that something is being deliberately hidden from him.
Miss Devine’s growing concern for Peter’s wellbeing introduces an outside perspective that starts pulling at the threads of his parents’ secrecy. Without spoiling the specifics, the film’s back half shifts from psychological unease into something considerably more physical and dangerous.
Cobweb Movie Ending Explained (Spoilers Ahead)
This section discusses the film’s ending directly, so stop here if you haven’t watched it yet. The voice Peter hears turns out to belong to Sarah, an older sister he never knew existed, who his parents have kept locked away inside the walls and basement for years.
Sarah explains that she was born with severe physical differences that terrified her parents, who chose to hide her away rather than raise her openly. She convinces Peter that his parents are dangerous and manipulates him into poisoning them on Halloween night, framing her captivity as an injustice he can help correct.
Once freed, Sarah reveals her true intentions aren’t reconciliation but revenge, turning on Peter and locking him inside the same wall she’d been trapped in. Miss Devine arrives in time to help free him, and together they manage to recapture Sarah and trap her back in the house’s hidden spaces before escaping. The film closes with Peter living under Miss Devine’s guardianship, while a final, lingering sound design detail suggests Sarah may still be alive and waiting inside the walls.
Is Cobweb Based on a True Story?
No, Cobweb is an entirely fictional story written by Chris Thomas Devlin. The screenplay was notable enough to appear on the 2018 Black List, a well-regarded annual survey highlighting some of the best unproduced screenplays circulating in Hollywood at the time.
Cobweb vs. the Korean Film of the Same Name
Anyone searching for this title should know there are two entirely unrelated 2023 films called Cobweb. The American horror-thriller covered in this guide stars Lizzy Caplan and focuses on a child’s discovery of a dark family secret.
The other film, directed by Kim Jee-woon and starring Song Kang-ho, is a South Korean comedy-drama about a film director obsessed with reshooting his movie’s ending. The two share nothing beyond a title, so double-checking which one a recommendation or review refers to avoids confusion.

Cobweb had a limited theatrical release through Lionsgate Films in the summer of 2023, before moving to digital and Blu-ray formats.

Critical Reception and Reviews
Cobweb received a generally positive critical response, with Rotten Tomatoes’ consensus describing it as an “itsy bitsy horror film” that “creeps and crawls” effectively despite its modest scale. Reviewers frequently praised Woody Norman’s performance as Peter, along with the film’s cozy, autumnal atmosphere.
The film’s box office performance was modest, earning around $10.1 million against a release that landed the same weekend as several much larger summer blockbusters. Its quieter theatrical run has since been offset by a stronger reception among horror fans discovering it through streaming and home video.
