Charlize Theron, Andy & Barbara Muschietti To Develop ‘The Final Girl Support Group’ Series Adaptation At HBO Max

EXCLUSIVE: HBO Max is developing The Final Girl Support Group, a TV series based on New York Times bestselling author Grady Hendrix’s horror novel of the same name. The project hails from Oscar winner Charlize Theron and her Denver & Delilah Films, It duo Barbara and Andy Muschietti’s Double Dream as well as Aperture Entertainment.

The novel’s title refers to a Los Angeles–based therapeutic support group for six “final girls”— survivors of mass-murderer rampages whose experiences inspired the slasher franchises that saturated horror cinema in the 1980s and ’90s, earning them minor celebrity. The book was released Tuesday, July 13 by Random House/Berkley.

Theron’s Denver & Delilah also has teamed with director Niki Caro to develop a feature film inspired by some of the top female surfers who are fighting for the right to compete in big-wave contests. It’s based on Daniel Duane’s New York Times Magazine article “The Fight For Gender Equality In One of the Most Dangerous Sports on Earth.”

Hendrix is currently adapting his novel Horrorstör for New Republic and Aperture. A feature adaptation of his novel My Best Friend’s Exorcism is in post at Amazon starring Elsie Fisher and Amiah Miller with Damon Thomas directing and Chris Landon (Happy Death Day) producing.
