There’s Someone Inside Your House is a 2021 American slasher horror film directed by Patrick Brice (Creep and Creep 2) from a screenplay written by Henry Gayden (Zombie Roadkill), based on Stephanie Perkins’ 2017 novel of the same name. James Wan’s Atomic Monster and Shawn Levy’s 21 Laps co-produced the movie for Netflix.
The adaptation is apparently “a combination of two different beloved teenage genres: the slashers that came to prominence in the ’80s and ’90s and the character-driven coming of age classics a la John Hughes’ films and American Graffiti.”
The movie stars Sydney Park, Théodore Pellerin, Asjha Cooper, Dale Whibley, Jesse LaTourette, Diego Josef, Burkely Duffield, Sarah Dugdale, William MacDonald, Andrew Dunbar and Markian Tarasiuk.
It’s been almost a year since Makani Young came to live with her grandmother in landlocked Nebraska, and she’s still adjusting to her new life. And still haunted by her past in Hawaii.
Then, one by one, the students of her small-town high school begin to die in a series of gruesome murders, each with increasing and grotesque flair. As the terror grows closer and the hunt intensifies for the killer, Makani will be forced to confront her own dark secrets…
There’s Someone Inside Your House premieres on Netflix on October 6, 2021.
Reviews of the book:
“The best new horror of the season… Fans of the genre will feel at home with this book, which mixes the wit of modern slasher films like Scream and I Know What You Did Last Summer with the grounded characters and emotions of contemporary YA.” Mashable
“Perkins lulls readers into a false sense of security before twisting the knife. . . . the body count keeps rising, leaving readers with questions of motive and where it will all end.” Publishers Weekly
“There’s Someone Inside Your House is a heart-pounding page-turner with an outstanding cast of characters, a deliciously creepy setting, and an absolutely merciless body count. Best read at night with big bowl of popcorn, this is a killer addition to the slasher genre written by one of the best contemporary YA writers around.” —Courtney Summers, author of All the Rage and Cracked Up to Be
