To celebrate Halloween, we bring you a triple-bill of impossibly rare 70’s exploitation trash. First, Blood Freak (1972), a sleaze classic with heavy Christian overtones in which ugly biker hippies smoke pot and turn into giant turkeys! Then, Boarding House (1979), a 42nd Street favorite: a boarding house turns into a blood-drenched inferno of death, and minds and faces are slashed open. And last but not least, it’s the inimitable Andy Milligan’s Bloodthirsty Butchers (1976), a loose version of the “Sweeney Todd” story, set in ye olde Victorian England (actually, Staten Island). Incomprehensible stretches of dialogue are mixed with decapitations, breast pies, and grotesque sex scenes. Stupefying! Be there or hate yourself in the morning. (Programmed by Joel Shepard)
