Peacock is getting a lot of horror movies in October, just in time for Halloween. But one of the most unsettling monsters is a real-life serial killer.

On October 16, Peacock is debuting its new true crime thriller, Devil in Disguise: John Wayne Gacy, which features Severance‘s Michael Chernus in the title role.

If you’re looking for something lighter, the live-action How to Train Your Dragon movie is coming out on October 10.

You can find those projects and more among Peacock’s new movies and TV shows in October 2025.
