October continues its tradition as a prime month for horror releases, with a diverse slate of films hitting theaters and streaming platforms. This year's lineup includes everything from creature features and psychological thrillers to a significant re-release of a controversial 1970s classic.

Kicking off the month on October 2 is "Beware Boiúna," a monster movie centered on a team of young doctors in the Amazon rainforest who encounter a mythological serpent. Also arriving on October 2 is "Verity," an erotic thriller based on a Colleen Hoover novel, directed by Michael Showalter. The film stars Dakota Johnson as a struggling ghostwriter hired to complete the work of a reclusive and ailing author, played by Anne Hathaway. "The Influencer Project," produced by "The Blair Witch Project" filmmakers Eduardo Sanchez and Gregg Hale, uses a found-footage approach to explore the darker side of influencer culture as a social media personality encounters a dangerous stalker in Copenhagen. Another October 2 release, "Appofeniacs," directed by Chris Marrs Piliero, delves into the chaotic potential of generative AI through a series of interconnected vignettes, featuring an ensemble cast including Sean Gunn.

Rounding out the early October releases is "Other Mommy," which gained viral attention for a disturbing trailer. Starring Jessica Chastain and directed by Rob Savage, the film is based on the book "Incidents Around the House" and follows a little girl haunted by a supernatural entity resembling her mother.

The latter half of October brings a mix of the familiar and the unsettling. On October 16, audiences can experience a 4K director's cut of Ken Russell's 1971 film "The Devils." Based on Aldous Huxley's novel, the controversial film depicts a 17th-century priest accused of seducing a convent and features performances from Oliver Reed and Vanessa Redgrave.
