October is the peak of spooky season, and HBO Max is certainly bringing its share of scares this month. The streamer is set to debut one of the year's most high-profile shows, IT: Welcome to Derry, just before Halloween, and Watch With Us can't wait to dive into the backstory of one of Stephen King's most famous stories. Other notable new fright flicks include the 2025 chiller Bring Her Back and the Oscar-nominated 2024 body horror The Substance, with Demi Moore and Margaret Qualley.
