This movie was made by an Italian horror master named Lucio Fulci, a.k.a. Godfather of Gore. It was given different names in different countries. In the UK, it is named Zombie Flesh Eaters, whereas in Italy it is named Zombi 2 because Dawn of the Dead (1978) of George Romero had been released as Zombi. So this one remained an in-name-only sequel to that. It has an original script and cinematography. Scenes of blood and gore are vastly used. Although it has numerous plot holes and continuity errors, it has become a classic due to some crazy scenes like a zombie fighting a shark and a horrible eyeball scene.
