In the late 1960s after a long and productive career, Boris Karloff, who was then in his late 70s and in poor health, was asked if he planned to retire. His reply was "He who rests...rusts! Not me. I plan to die in harness." And that's just what he did...almost. He died at 81 just two months after completing a series of four Mexican pictures. While his persistence was admirable, his final cinematic efforts were not. In fact they were pretty awful rivaling the movies that Bela Lugosi made at the end of his career for Ed Wood. This wasn't Karloff's fault. In fact he seemed more energetic in these last four films then he had been in the previous four bigger budget movies where he had been primarily seated in a wheelchair. The problem was in the way these Mexican titles were put together.
His health and the high altitude kept Karloff from going to Mexico City to shoot the films and so his scenes were all shot in Hollywood with an American director (Jack Hill) and an American script. Once his scenes were in the can, the Mexican portions using Mexican actors were filmed and then Boris' scenes were edited in. Director Hill, who had made the cult favorite SPIDER BABY with Lon Chaney Jr, was an old hand at creating composite films. Usually foreign films were purchased and then American scenes were shot and fitted into them. For these Mexican movies the process was reversed. Once back in Mexico, the producers rewrote the original scripts and did pretty much what they wanted including the addition of unsavory and rather violent material.
Fortunately Boris died before he had a chance to see these hybrid curiosities and so it is left for fans of BK to make of them what they will. Unquestionably the best of the lot was the first screenplay, HOUSE OF EVIL, which recycles the story of the dying patriarch and the greedy relatives gathered for the reading of his will. The twist here is that they are bumped off by his collection of mechanical toys. Next came ISLE OF THE SNAKE PEOPLE, a tale of zombies with Karloff as the head of a voodoo cult. The third to be filmed was THE INCREDIBLE INVASION which borrows from Karloff's THE INVISIBLE RAY (1936) and adds outer space aliens. Finally there was THE FEAR CHAMBER which is the weakest so you could say that each movie got progressively worse.
The first two were released a year after being completed. The last two had to wait until 1971 which was two years after Karloff died. All four played the drive-in circuit as double features and were quickly forgotten. In 1987, twenty years after the films were made, a company called Parasol Group Ltd released them on VHS in an edited form and gave them new titles. They became, in order, DANCE OF DEATH, CULT OF THE DEAD, ALIEN TERROR, and TORTURE ZONE. All four are characterized by cheap sets, unimaginative photography, and are badly dubbed. CULT and ZONE have brief nudity and some graphic violence. It is these rather flat looking VHS copies that VCI has issued on DVD as part of their Sprocket Vault series.
