This audaciously disgusting spectacle from the late master of gruesome horror, Lucio Fulci, was posited as a semi-sequel to George Romero's Dawn of the Dead, which was released in Italy as Zombi. Tisa Farrow and a group of vacationing tourists travel to an island where they find a doctor (Richard Johnson) who is attempting to cure a condition that reanimates the dead. Things quickly get out of control as undead Spanish conquistadors crawl from their graves hungry for human flesh. The nauseatingly graphic set-pieces by Gianetto de Rossi include a close-up of a woman's eye being pierced by a large shard of wood and a zombie fighting a Great White shark underwater. This relatively well-made shocker was enormously popular worldwide and led to the zombie-gore film becoming the dominant motif of 1980s Italian horror.
