Director Richard Jefferies penned this silly late grindhouse flick with Nico Mastorakis, and the latter's usual monsters and human sacrifice are prominent here. What's amazing is that an impressive cast was assembled for a B-movie like this: James Earl Jones (awful as an obnoxious treasure hunter) just prior to his universally overrated prime, a wizened and weathered José Ferrer, Mary Louise Weller in her last feature film (fresh from the successes of Animal House and Q: The Winged Serpent) and a perpetually shirtless Martin Kove, who performs capably without any of the delightfully silly menace that he cultivated in The Karate Kid. Of the lot, only Ferrer and Weller manage to salvage their dignity with convincing performances.
The plot? Eh, something about pushy Americans who encounter an ancient, virgin-gobbling sea monster off the coast of a rural Greek island. Who cares? What's worth seeing here are the scenic locations, and especially a lovely old Catholic monastery. Jefferies actually does exhibit some competence by generating some atmosphere with the aid of the locale; unfortunately, the movie's story is too boring and stupid to amount to much.
