Trivia, insights & behind the scenes
Loosely based on Val Lewton's 1943 I Walked With a Zombie, though this version dumps the poetry for exploitation. The original was a meditation on colonialism; this is Jennifer Grey running from guys in masks.
This was originally shot as a Tales from the Crypt feature in 2001, got shelved, then had all Crypt elements removed and became standalone 'Ritual.' The Cryptkeeper's scenes were literally burned. Yes, really.
