The Toronto International Film Festival (TIFF), one of the world's most prestigious film events, offered a sneak peek this year at several horror-themed and horror-inspired series set to launch in October. Four major streaming platforms — Peacock, Netflix, Amazon Prime Video, and AMC — used the festival to showcase early looks at their upcoming projects, highlighting the growing importance of the Halloween season in the streaming industry. As horror content continues to attract large audiences, platforms are increasingly investing in the genre to capture viewer attention during this popular time of year. One of the most anticipated projects is Carrie, an adaptation of Stephen King’s classic novel. Set to debut on Amazon Prime Video on October 7th, the series is directed by Mike Flanagan, known for his work on Netflix’s The Haunting of Hill House and Midnight Mass. Flanagan has brought a modern twist to the story, incorporating themes like cyberbullying and expanding the narrative into a series format. This is his first project since joining Amazon in 2022. Netflix is also set to release Below on October 8th, a six-episode series that follows a small fishing village in Newfoundland terrorized by an ancient sea creature. The show stars Josh Hartnett as a fisher struggling with personal and family issues while trying to survive the creature’s attacks. The series blends supernatural horror with elements of drama and suspense. Peacock will premiere Crystal Lake on October 15th, a prequel to the Friday the 13th franchise. The show explores the backstory of Pamela Voorhees, the mother of Jason Voorhees, and is described as both tense and dramatic. Linda Cardellini stars as Pamela, and the series is expected to include classic slasher-movie elements, including gore and dark humor. AMC Plus will release Yaga on October 23rd, a supernatural detective series with a cast that includes Matrix star Carrie-Anne Moss and Hudson Williams. While details about the plot were limited, the trailer has been described as intriguing and mysterious. The release of these series comes as horror content continues to thrive, with recent successes like Backrooms, Obsession, and Widow’s Bay boosting the genre’s popularity. Streaming platforms are capitalizing on this trend by showcasing new projects at events like TIFF to build anticipation and attract viewers.
