Not a direct sequel to Brides of Blood (1968) but in today’s vernacular this would be taking place in a “Bloodverse”. Swap human sacrifice for erotic ritual, eliminate the man-eating trees and giant insects, throw in buckets of green blood and women who can’t pass a waterfall without diving in naked, a voyeur, add a touch of estrangement, remove any mention of radiation, and while there’s clearly a monster on the loose a strange doctor appears as much of a liability. To keep the exploitation audience onside, there’s more nudity, plus sex. To keep the arthouse fans happy there’s innovative camera use, a kind of shuddering disorienting effect as the camera jumps back and forward.
This time round our visiting scientist, pathologist Dr Bill Foster (John Ashley), is investigating a strange disease that’s broken out on the island. Accompanying him are non-scientists Sheila Willard (Angelique Pettyjohn) looking for her father (Tony Edmunds) and Carlos (Ronaldo Valdez) who’s planning to persuade his widowed mother (Tita Munoz) to leave. Dr Lorca, the local authority, welcomes the visitors.

None of the new arrivals have much luck. Sheila’s father is a hopeless alcoholic and doesn’t view with any interest reuniting with his daughter while Carlos’s mother refuses point blank to leave. Worse, his father, it transpires died in mysterious circumstances several years before. Dr Lorca is generally obstructive.
It takes a good few sightings of the monster, not a giant as such beings often are, but the size of a normal human with skin a funny color and extremely mottled, to keep things going. Generally speaking, said monster, as in the previous film, has a predilection for naked women, though their nudity doesn’t always seem linked to skinny-dipping under a waterfall.
Finally, the monster becomes more inquisitive and invades the house where the guests are staying. Sheila, who makes the mistake of wandering out into the jungle alone, is attacked by the monster but escapes.

Carlos discovers his father’s coffin is empty. Sheila and Bill hit it off, sufficiently enamored of each other that they make love in a cave. About the only contribution Bill makes, apart from being one-half of the love interest, is to track the monster to a cave where people are being kept prisoner.
The warder is Dr Lorca who has been carrying out experiments on the natives, one of his earliest victims being Carlos’ father Don Ramon who is the current monster. For no apparent reason, except he’s a monster, Don Ramon kills his wife and then because he’s not completely a monster but still has human feelings lets his son go free, instead turning his vengeance onto Dr Lorca and in the carnage that follows apparently killing himself.
But not so fast. As had already been demonstrated in the 1960s, success could breed instant further success, franchises now abounding, not just James Bond, Matt Helm, Harry Palmer and Derek Flint but The Magnificent Seven and The Pink Panther, so nobody was going to pass up the opportunity to make a few more bucks. The door is opened for a sequel when the final shot picks out the hand of the monster hiding in a lifeboat on the ship ferrying away the survivors.
This is more of a cliché than Brides of Blood and some scenes such as the erotic ritual and dalliance at waterfalls and in caves seemed intent on hooking an audience other than horror. Once again, it’s the female lead who steals the picture – though it’s not much of a fight. Angelique Pettyjohn (Heaven with a Gun, 1969) has not just the heaving bosom of her predecessor and her sassiness but a more solid emotional journey.
You’re not going to expect much genuine emotion in a horror picture of the period but in that respect Pettyjohn and, surprisingly, the monster come off best.
Again directed by Eddie Romero and Gerardo De Leon from a script this time round by Reuben Canoy (The Passionate Strangers, 1966).
Passable.
