Zombie Holocaust, (Original title: Zombi Holocaust) also known as Zombie 3 and Doctor Butcher, M.D., is a 1979 Italian zombie movie, directed by Marino Girolami.

Zombie Holocaust (also known as Island of the Last Zombies, Medical Deviate and Dr. Butcher, M.D.) goes for the jugular and rips it out gushing in a full-on shock to the system.  In an effort to expose a flesh-eating cult in New York City, Dr Peter Chandler (Ian McCulloch from Zombie Flesh Eaters ) and Lori Ridgeway (Alexandro Delli Colli) set out on an expedition to the primitive island of Keto – determined to uncover the origins of this mad zombie cult. Here they encounter a tribe of cannibals and a mad scientist who is experimenting and delving into the dark arts –  reanimating dead corpses. Four of his walking-dead experiments roam the island with an insatiable hunger for human flesh.Uncut and now in grisly high-definition, abounding with bloodshed and hardcore gore, this Italian horror classic is a cult assault on the senses and a must for any zombie film fan.
