Best Horror of October 2026: Other Mommy, Carrie, Whalefall, Clayface and More

October is here, and the horror genre is delivering one of its strongest months in years. From prestige streaming series to theatrical creature features, October 2026 has something for every kind of horror fan. Whether you are into slow-burn folk horror, slasher nostalgia, or claustrophobic thrillers, this month’s lineup is stacked. Here is your guide to the best horror movies and series to watch this October.

Other Mommy — Jessica Chastain Goes Full Horror

Leading the charge is Other Mommy, a theatrical release from Universal Pictures on October 9. Jessica Chastain returns to horror, playing both a family matriarch and a supernatural beast that takes her form. Jay Duplass and Arabella Olivia Clark play the husband and daughter in peril in Rob Savage’s film. The premise alone is enough to give you chills: a creature that looks like your mother but is anything but. Chastain has proven her genre chops before, and this looks like a career-best performance. If you are a fan of body horror with emotional weight, this is your must-watch of the month.

Carrie — Mike Flanagan Reimagines a Classic

Mike Flanagan is no stranger to horror. The director behind The Haunting of Hill House and Midnight Mass is taking on Stephen King’s Carrie for Amazon Prime Video, debuting October 7. Summer H. Howell stars in the title role, with Flanagan regulars like Samantha Sloyan, Matthew Lillard, Kate Siegel, and Rahul Kohli rounding out the cast. This is a modern telling of the telekinetic girl mercilessly bullied by her peers and overbearing mother. Flanagan’s track record with King adaptations is impeccable, and this cast is stacked. If you love character-driven horror that earns its scares, Carrie should be at the top of your watchlist.

Whalefall — A Claustrophobic Nightmare

From 20th Century Studios comes Whalefall, in theaters October 16. Austin Abrams plays a scuba diver who gets swallowed by a whale and must escape before his oxygen runs out. Director Brian Duffield’s last film, the nearly dialogue-free alien invasion movie No One Will Save You, was fantastic, so expectations are high. The trailer alone is a nail-biter. This is survival horror at its most primal: one man, one creature, and a ticking clock. If you like your horror tight, tense, and relentless, Whalefall is for you.

Clayface — DC’s Body Horror Villain

Warner Bros. is betting on body horror with Clayface, in theaters October 23. Mike Flanagan wrote the story and co-wrote the script for this Batman villain standalone. The trailer promises a frightening and squeamish body horror tale. “Speak No Evil” director James Watkins helms this ambitious DC Universe film. Clayface is one of Batman’s most visually striking villains, and leaning into body horror is the right call. If you are a DC fan or just love grotesque practical effects, this is one to watch.

Below — Josh Hartnett Hunts Sea Monsters

Netflix is getting in on the October horror action with Below, debuting October 8. Josh Hartnett plays a fisherman in a Newfoundland town who must battle a sea creature. Mackenzie Davis, Charlie Heaton, and Natasha Henstridge also star. Early footage looks stylish and spooky. This is creature-feature horror with a maritime twist, and Hartnett’s return to genre work is welcome. If you like your horror with a side of ocean dread, Below is worth your time.

Crystal Lake — The Friday the 13th Prequel

Peacock is diving into slasher lore with Crystal Lake, debuting October 15. This Friday the 13th prequel series is a deep dive into the psyche of slasher icon Jason Voorhees’ mother, Pamela. The production comes from A24, stars Linda Cardellini, and was created by It: Welcome to Derry co-showrunner Brad Caleb Kane. That is a tremendous amount of talent that could elevate the show beyond typical slasher fare. If you have ever wondered what made Jason who he is, Crystal Lake promises to answer that question.

V/H/S/Mixtape — The Anthology Returns

The long-running Shudder anthology series continues with V/H/S/Mixtape, debuting on Shudder October 9. The ninth installment has a music-driven focus, with contributions from Ernest Dickerson, Flying Lotus, RZA, David Moreau, and Renee Zhan. The initial press release promised “outrageous splatter and groundbreaking practical effects.” If you are a fan of the franchise’s found-footage chaos, this is your Halloween treat.

More Horror to Watch This October

The October horror slate does not stop there. Beware Boiúna (Lionsgate, October 2) is a giant killer snake story from director Mike P. Nelson, who delivered strong horror reboots with Wrong Turn and Silent Night, Deadly Night. Crawlers (RoadsideFlix, October 16) is a creature feature about deadly spiders loose in an apartment building.

Books and Festivals for the Full Horror Experience

October is not just about screens. Jane Schoenbrun, the filmmaker behind I Saw the TV Glow, releases their debut novel Public Access Afterworld on October 27 via Hogarth. The book involves a group of people through the decades whose lives are changed by an unexplainable TV network called Public Access Afterworld. A web of conspiracy and horror follows. If you are a fan of Schoenbrun’s work, this is a must-read.

And for those who want to experience horror in a community setting, FilmQuest runs from October 22-31 in Provo, Utah. The genre film festival is filled with creatives eager to celebrate wild movies and network with like-minded fans.

If you are looking for the next big horror discovery, festivals like this are where it happens.
