THE NORTH AMERICAN UHD PREMIERES. FULLY RESTORED. TOTALLY UNCUT. MORE DEPRAVED THAN EVER BEFORE! It sparked riots on 42nd Street, spawned a generation of gorehounds on VHS, forever set an insane standard for Italian zombie/cannibal carnage worldwide, and is now presented in UHD: Ian McCulloch (ZOMBIE), Alexandra Delli Colli (THE NEW YORK RIPPER), Sherry Buchanan (TENTACLES) and Donald O'Brien (EMANUELLE AND THE LAST CANNIBALS) star in this unabashed EuroTrash orgy of gut-munching, eyeball-gouging and face-chopping originally known as ZOMBIE HOLOCAUST, which a notorious American distributor would then re-edit, re-title as DOCTOR BUTCHER M.D. and re-release as a certified grindhouse masterpiece. Severin Films now presents both films scanned in 4K from original vault elements discovered in Manhattan and Rome with 4 hours of archival and all-new Special Features that reveal the unbelievable truth behind it's bizarre history, infamous marketing and still-deviant legacy.
