Curse of Halloween (2006)

Not to be confused with the innumerable installments of the Halloween series featuring masked killer Michael Myers - or Rob Zombie's 2007 remake of the 1978 horror blockbuster - the low-budget, direct-to-video frightfest Curse of Halloween involves several unfortunates cursed to die on October 31st from waking The Great Queen Pumpkin via a sacrifice. She (or it) goes out on a killing spree, massacring everyone in her wake. The initiators must stop her before the entire town is annihilated.
