My review was written in November 1986 after a screening at Liberty theater on Manhattan's 42nd Street.
"Monster Shark", previously titled "Red Ocean", is a poor science fiction/horror film from Europe. Since Universal is planning a fourth "Jaws" epic, there's apparently some life left in this lame material.
Yank actor Michael Sopkiw gets involved in a hunt for a giant underwater killer off the Florida oast when he's hired to rig up some electronic equipment for scientists studying the series of gory attacks on humans. Eventually they discover that the culprit is a 15,000,000-year-old ancestor of the shark, 40-feet long and hungry. Worse yet, the critter's individual cells are capable of reproduction, meaning that if it isn't found and destroyed soon the ocean will be filled with the beasties.
Cornball film relies once again for the usual conflict between gung ho scientists (led by William Berger) who want to save the creature for study, and practical types like the local sheriff (Gianni Garko) who want to kill it. Monster itself is a very fake-looking cross between shark and octopus, wisely shown in its entirety only briefly on screen. Cast is peppered with pretty women, but the acting is miserable, becoming downright funny during some exaggerate death scenes or shrieking bouts.
Surprisingly for such a routine picture, five well-known Continental helmers are credited in various capacities, wit the Italian contingent (Lamberto Bava, the film's director, as well as Luigi Cozzi and Sergio Martino) hiding behind pseudonyms, while their French confreres, Max Pecas and Gilbert Roussel, are less shy.
