Island of the Fishmen ( ) is a 1979 action horror film directed by Sergio Martino, starring Barbara Bach, Joseph Cotten and Richard Johnson.

In 1981, about 30 minutes of footage was removed from the original film and replaced with new material for international release. This version was given the title Screamers.

It is the year 1891 and a military doctor, Lieutenant Claude de Ross (Claudio Cassinelli) a survivor of not one, but two shipwrecks, washes ashore on a mysterious, uncharted Caribbean island along with a handful of convicts. When several of these convicts meet unfortunate ends at the hands of the titular fishmen, Claude and the other survivors flee into the jungle, only to encounter the sadistic Edmond Rackham (Richard Johnson) and his beautiful captive Amanda Marvin (Barbara Bach).

Amanda's father, Professor Ernest Marvin (Joseph Cotten), a once-famed biologist, has discovered a way to transform humans into amphibious creatures and controls their every move. Rackham manipulates Marvin into performing the procedure upon both willing and unwilling participants by assuring him that his work is undertaken for purely scientific and humanitarian motives (Marvin hopes to reduce strain on the world food supply by creating a race of people who can live in the resource-untapped ocean). Having discovered the lost city of Atlantis beneath the waters surrounding the island however, Rackham is in actuality using the half-human monsters to plunder the lost city of its treasures.
