'American Horror Story' Season 12: Everything to Know

American Horror Story season 12 is quickly coming together.

The upcoming season was first confirmed in January 2020, when FX renewed the Ryan Murphy series for three additional seasons.

"Ryan and Brad are the undisputed masters of horror TV, having created the anthological limited series with American Horror Story and sustaining its success for nearly a decade as FX's highest-rated series," FX chairman John Landgraf said in a statement. "We are grateful to them and Dana Walden and our studio partners for committing to another three years."

Since then, casting announcements have been trickling in, with AHS alum Emma Roberts slated to return.

Kim Kardashian joined the cast in April, marking one of her biggest acting roles yet. (Though best known for her reality shows, Keeping Up with the Kardashians and The Kardashians, she has previously acted in Disaster Movie, CSI: NY and Drop Dead Diva and made cameos as herself in Ocean's Eight, 2 Broke Girls and 30 Rock.)

From the confirmed cast members to the theme, here's everything to know about AHS season 12.

Who is in the cast of American Horror Story season 12?

Matt Czuchry was one of the first cast members reported to star in AHS season 12, with The Hollywood Reporter noting that he was joining the franchise following the cancellation of his FX series The Resident in April 2023.

Later that month, Murphy confirmed Emma Roberts and Kim Kardashian's roles on the show with a cryptic teaser on Instagram.

"Kim is among the biggest and brightest television stars in the world and we are thrilled to welcome her to the AHS family," said Murphy in a statement to THR. "Emma and I are excited about collaborating with this true force in the culture. Halley Feiffer has written a fun, stylish and ultimately terrifying role especially for Kim, and this season is ambitious and unlike anything we have ever done."

THR also noted that Murphy was impressed with Kardashian's "well-received 2021 hosting gig on Saturday Night Live" and began speaking with the reality star "last summer about crafting a unique role for her scripted TV debut."

In April 2023, Cara Delevingne joined the cast, though details of her character were not revealed.

The trailer released on Sept. 6 also confirmed Michaela Jaé Rodriguez, Billie Lourd, Leslie Grossman and Denis O’Hare are set to appear in the new season.

What is the theme of American Horror Story season 12?

This season will be titled American Horror Story: Delicate. Unlike previous seasons, which were original stories based on various themes, this season will be based in part on Danielle Valentine's upcoming novel Delicate Condition.

The novel, which will be released in August 2023, is "described as a gripping thriller about a woman who becomes convinced that a sinister figure is going to great lengths to make sure her pregnancy never happens," per THR. It's also been described as "the feminist update to Rosemary's Baby we all needed," per author Andrea Bartz.

Is there a trailer for American Horror Story season 12?

In July 2023, FX dropped the first official teaser for season 12 — giving fans a quick look at Kim Kardashian, Emma Roberts and Cara Delevingne in costume. All three women donned white hair, lengthy eyelashes and a red lip. At the end of the 30-second clip, Kardashian can be seen cradling a baby while a creepy rendition of “Rock-A-Bye Baby" plays in the background.

A month later, the second official teaser was released. The clip shows Roberts running from human-spider hybrids after Delevingne, who plays a sinister-looking doctor, appears to have impregnated her with a spider baby.

The official trailer was released on Sept. 6, giving a frightening look at the journey Roberts' character takes as she becomes pregnant and has disturbing visions involving spiders.

Who is writing American Horror Story season 12?

For the first time in the show's history, the upcoming season will be written and showrun by one person, Halley Feiffer, who previously wrote for Murphy's series Impeachment: American Crime Story.

Additionally, the new season will be executive produced by Murphy, co-creator Brad Falchuk, Feiffer, Alexis Martin Woodall and Scott Robertson.

When will American Horror Story season 12 be released?

The new season will premiere on Sept. 20. According to Deadline, the upcoming season will premiere in two parts, however, it's clear how the episodes will be split. 

Will there be an American Horror Story season 13?

In January 2020, FX announced at the 2020 TCA's press tour that the long-running hit anthology horror series has been renewed for three more seasons, securing its presence on the network until at least season 13. However, cast and plot details for season 13 haven't yet been released.
