What Santa and the Ice Cream Bunny is to Christmas, director Brad Grinter’s infamous 1972 opus is to Thanksgiving: namely, a rancid spoonful of cinematic castor oil guaranteed to cure you of holiday spirit. In this Florida-shot Christian scare film, a dude takes LSD and faces the inevitable consequences. Which is to say, he morphs into a giant turkey monster with a head that looks like the ham costume the kid wore in To Kill a Mockingbird, then menaces victims with a terrifying “Gobble!” (I am not making this up.) In between shocks, director Grinter chain-smokes and hack-coughs his way through the story’s moral lessons in front of the grubbiest plywood-paneling set this side of an amateur porn festival. Thank the folks at Logue’s basement Cult Fiction Underground grindhouse for serving up this casserole dish of maggot-ridden stuffing.
