Blood Tide (1982, GBR/GRE) C-83m. *½ D: Richard Jefferies. Starring James Earl Jones, José Ferrer, Lila Kedrova, Mary Louise Weller, Martin Cove, Deborah Shelton. Boring horror film set on a Greek island, where young couple come in search of a missing sister, only to find under the thrall of sect-like community led by Ferrer. Will they sacrifice her to some kind of monster? Hardly any action or suspense, a downer. Only the cast is remotely interesting. Coproduced by Nico Mastorakis (also cowriter), Brian Trenchard-Smith. Original British version runs longer. Also known as DEMON ISLAND, THE RED TIDE.
