By 1971, drive-ins across America were clamoring for a new BLOOD ISLAND movie. But with de Leon/Romero busy creating the ‘machete maidens’ genre, Hemisphere instead turned to writer/producer/distributor Sam Sherman (SATAN’S SADISTS) and director Al Adamson (BLOOD OF DRACULA’S CASTLE) to deliver a comparable saga of gruesome shocks and mad doctor mayhem. The result – the only Hemisphere production to be shot outside the Philippines – remains the insane epitome of low-budget ‘70s horror and one of Adamson’s most infamous epics. Kent Taylor (BRIDES OF BLOOD), Grant Williams (THE INCREDIBLE SHRINKING MAN), Regina Carrol (ANGELS’ WILD WOMEN), John Bloom (THE INCREDIBLE 2 HEADED TRANSPLANT), Angelo Rossitto (FREAKS) and Zandor Vorkov (DRACULA VS. FRANKENSTEIN) star in this “great bloody film” (Grindhouse Database) – also known as THE CREATURE’S REVENGE and THE OOZING SKULL – now featuring a new 2k CRI scan.
