'Burial Ground' aka 'Nights of Terror' (1981) – Andrea Bianchi.

No stranger to celluloid controversy, the bravura exploitation maestro Andrea Bianchi's salaciously sleazy Giallo classic 'Strip Nude for your Killer' wholly successfully turned his luridly crimson eye onto the then hugely popular cycle of exhilaratingly exsanguinating Euro-zombie splatter excess, gorily unleashing his very own uninhibitedly gruesome, morbidly maggot-ridden horde of pus-slathered, disgustingly decayed, gruesomely gormandizing, gut-munching ghouls upon the woefully ill-prepared inhabitants of a no less decayed, and grimly dilapidated country estate, fatefully built upon the increasingly restless remains of an ancient Etruscan burial ground! The continued notoriety of Italian B-Movie master Bianchi's corpse-clotted, Tomb-trashingly salacious splatter disasterpiece relies not only upon the plentiful grisly practical effects by make-up maestro Gianetto Di Rossi, but the manifestly bizarre presence, and singularly odd acting stylings of pint-sized simp Peter Bark, awkwardly playing mewling mummy's boy Michael whose decidedly titty-twisted Oedipal complexity leads to horror cinema's most memorably disturbing mammary mutilation that remains the very breast of its unkind! With a suitably schizo score by Elisio Mancuso and Berto Pisano, Andrea Bianchi's hell-spawned zombie holocaust is one long screaming night of terror that will wake the dead!!!!
