There's Someone Inside Your House: Release Date, Cast, And More

(Welcome to ...And More, our no-frills, zero B.S. guide to when and where you can watch upcoming movies and shows, and everything else you could possibly stand to know.)

I don't want to alarm you, but..."There's Someone Inside Your House," at least according to the upcoming Netflix horror flick. The film is based on the novel of the same name by Stephanie Perkins and hails from "Creep" director Patrick Brice. Even though the film comes out relatively soon, there's not much info out there about "There's Someone Inside Your House," which is why I'm here to help. 

"There's Someone Inside Your House" is currently set to arrive on October 6, 2021, and the film is going straight to Netflix. While the streaming service has a few fall titles that will have limited theatrical runs first, this isn't one of them. So you won't have to weigh your options between theater and home — it'll just show up on your TV and/or phone.

"There's Someone Inside Your House" is a new teen-centric horror movie headed to Netflix, who just had themselves a teen-horror hit with the "Fear Street" trilogy, so here's hoping this is just as good. The film is adapted from the novel by Stephanie Perkins. 

Here's the film's official synopsis: 

Makani Young has moved from Hawaii to quiet, small-town Nebraska to live with her grandmother and finish high school, but as the countdown to graduation begins, her classmates are stalked by a killer intent on exposing their darkest secrets to the entire town, terrorizing victims while wearing a life-like mask of their own face. With a mysterious past of her own, Makani and her friends must discover the killer's identity before they become victims themselves.

And, just for fun, here's the book synopsis, too. 

It's been almost a year since Makani Young came to live with her grandmother and she's still adjusting to her new life in rural Nebraska. Then, one by one, students at her high school begin to die in a series of gruesome murders, each with increasing and grotesque flair. As the body count rises and the terror grows closer, can Makani survive the killer's twisted plan?

"There's Someone Inside Your House" comes from director Patrick Brice, who is also responsible for "Creep" and "Creep 2." Henry Gayden ("Shazam!") wrote the script. Producers include Shawn Levy, James Wan, Dan Cohen, and Michael Clear. Jeff Cutter is the cinematographer. Michel Aller is the film's editor. The music comes from Zachary Dawes. 

The cast for "There's Someone Inside Your House" includes Sydney Park, Théodore Pellerin, Asjha Cooper, Dale Whibley, Jesse LaTourette, Diego Josef, Burkely Duffield, Sarah Dugdale, William MacDonald, Andrew Dunbar, and Markian Tarasuik.
