You can tell Screamers is pure Italian schlock because the monsters are dripping with olive oil.

Originally titled Island Of The Fishmen, it’s a bit of an H.G. Wells mashup of Mysterious Island and The Island of Dr. Moreau, as Claude, a young naval doctor (Claudio Cassinelli) washes ashore in the Caribbean after the sinking of the prison ship to which he was assigned.

He and two surviving prisoners are taken to the wicker plantation home of wealthy misanthrope Edmond Rackham (Richard Johnson) and his stunning lady friend Amanda Marvin (Barbara Bach, aka Mrs. Ringo Starr). Together they preside over a household of voodoo enthusiasts, led by high priestess Shakira (Beryl Cunningham).

A tired-looking Joseph Cotten shows up long enough to play Amanda’s mad (but seemingly decent) scientist pappy, who is determined to create a new race of oily gill men to populate the oceans of the world. His experiments are then employed by Rackham as cheap labor to loot the treasure vault of a nearby submerged temple.

Oh yeah, and it’s a volcanic island that’s gonna blow any second.

Directed by giallo veteran Sergio Martino (Slave Of The Cannibal God, Torso, Blade Of The Ripper), Screamers isn’t nearly good enough to be lost treasure, but it’s brisk, watchable trash with a decent budget, and Barbara Bach is radiant.

I already checked, you don’t have anything better to do.
