7 new horror movies on Netflix, HBO Max, Shudder, and more in September 2026

September is upon us, and in many countries we'll be preparing for cold weather and cozy nights in front of the TV.

If you're looking for a good horror movie for a night in, there's plenty across the best streaming services this month.

Indeed, the streaming giants have added more new movies to their libraries, whether you're in the mood for big new releases, indie horror gems, or classics you haven't watched in ages.

Here's seven horror titles that caught my eye in September 2026.

Carrie (1976) When: September 1 Where: HBO Max (US); MGM+ (UK); 7Plus (AU) Ahead of Mike Flanagan's Carrie series on Prime Video, why not watch the original Brian De Palma movie? I love revisiting this horror classic, based on Stephen King's first novel.

Here, Sissy Spacek plays the titular role opposite Piper Laurie's terrifying performance as Carrie's overbearing mother, Margaret.

After suffering bullying from her classmates and abuse from her mother, Carrie finally snaps on prom night, resulting in one of horror's most iconic scenes.

Sinister When: September 1 Where: Hulu (US); Lionsgate+ (UK); Stan (AU) Before he became The Grabber in The Black Phone , Ethan Hawke was being terrorized by a demonic presence.

In Sinister , he plays a true crime writer who discovers snuff films and attempts to piece together what happened to the victims.

This is a very scary watch with some great jump scares, one of which is widely regarded as one of the best jump scares in modern horror.

So if you want to be sleeping with the lights on, Sinister is a great movie to stream this month.

Ready or Not When: September 1 Where: Netflix , Hulu (US); Disney+ (UK, AU) Sequel Ready or Not 2: Here I Come recently landed on Disney+, so you could have yourself a double bill and check out the first movie now it's streaming across some of the best streaming services.

In Ready or Not , Grace (Samara Weaving) marries into a wealthy family who made their fortune making puzzles and games.

On her wedding night, she is invited to play hide and seek as part of a tradition, but it soon turns out to be much more deadly than she'd expected and she ends up fighting to stay alive.
