Directed by Lamberto Bava.

Starring Michael Sopkiw.

IMDB

One of a few legendary Jaws-rip offs from the Italians. Movies such as Enzo G. Castellari's "The Last Shark" and Bruno Mattei's "Cruel Jaws" were so slavish to the original that they actually used footage directly ripped from the blockbuster Spielberg film (and were sued because of it).

This one tries to be more coherent but it ends up being less entertaining because of it. This is a true stink bomb from the wildly uneven Lamberto Bava who was sometimes capable of great films like "Macabre" (1980) and "Demons" (1985).

This is also one of Michael Sopkiw's last films, though he has only done 5 in his whole career. Still, he's a memorable leading man, especially in Italian jungle fare like "Massacre In Dinosaur Valley" (1985) and as a Mad Max-like warrior in "2019: After The Fall Of New York" (1983).
