Dr. Obrero (Dan O' Brien) is experimenting on corpses on a remote Island. Well, an expedition team (which includes Zombi 2's Ian McCulloch) ends up on the island-and runs into the Docotor, who has some plans-as well as cannibals and zombies-in store for them.
Titled "Dr Butcher M.D." when it came to video in the 80's, "Zombie Holocaust" is an interesting-and fun-blend of two different kinds of Italian Gore flicks: The Italian Zombie movie, and the Italian Cannibal movie-only without any of the animal torture and mutilation of the later.
The movie has some nice gore (surgical and otherwise-including an awesome motorboat engine to the head death) and nudity to liven things up, as well as a fun score and tons of camp. Also, unlike other Italian gore flicks of the time, the movie features a little intentional humor to go with it ("The patients screaming disturbed me, performed removal of vocal chords"-that line always gets me), which after the downbeat feeling of Fulci's zombie movies, is something of a breath of undead air. It's nice to see an Italian gore flick that doesn't take itself too seriously for a change.
If there is any problem, it's that the zombie aspect feels rather underplayed, as they aren't used for much. Sure, there's that aforementioned death by boat motor, but they don't do a whole lot to threaten the team, as the cannibals are more of a threat. Still, "Zombie Holocaust" is a blast of exploitation that fans of over the top Italian Horror might enjoy. I know I did.
