Hallowarrior stars Milly Shapiro as Pumpkin, a post-plague survivor facing raiders on Halloween; Ben Sottak directs. The Cycle, directed by Jordan Downey, gives Deborah Ann Woll a different problem: her estranged father’s body reappears after 36 years at a horrific crime scene, turning a forensic mystery into supernatural horror.
The second premise has more dramatic leverage. The 36-year absence creates a family history before the supernatural mechanism begins. AMC announced both as Shudder originals, and October reporting describes both as streaming there, but authenticated current US playback was not tested.
