Island of The Fishmen

Taking its narrative cues from H.G. Wells' classic tale of mad science and jungle madness THE ISLAND OF DR. MOREAU and H.P. Lovecraft's THE SHADOW OVER INNSMOUTH, director Sergio (TORSO) Martino's delirious and bizarre ISLAND OF THE FISHMEN (aka L'isola degli uomini pesce) is an Italian genre film like no other.
After surviving two harrowing nautical disasters, Lieutenant Claude de Ross washes up on a remote, uncharted tropical island along with a gaggle of similarly stranded escaped convicts. Soon, the cursed castaways are attacked by gruesome, slimy, scaly monsters and, after many of them meet their grisly ends, the rest - including the fortunate de Ross - are rescued by the cruel Rackham who immediately whisks them away to the jungle lair of Professor Ernest Marvin. Marvin, a disgraced American biologist, has tampered with genetics to create an army of fishmen, the very same creatures that attacked de Ross. Professor Marvin controls the creatures and has been using them to plunder a submerged city of gold that he believes to be the lost city of Atlantis. But the natives are restless and the fishmen are slowly, surely beginning to hatch their own plans.
Will de Ross - along with the professor's comely daughter - find away to escape the island before its too late?
