Neptune Factor, The (1973, CDN) C-98m. SCOPE **½ D: Daniel Petrie. Starring Ben Gazzara, Walter Pidgeon, Ernest Borgnine, Yvette Mimieux, Donnelly Rhodes, Chris Wiggins, Michael J. Reynolds. Canadian addition to the disaster film canon of the 1970s, this is little-known because its budget and cast weren't quite as big as that of the other pictures. An ocean lab falls into an abyss after an earthquake, and Gazzara's submarine is the only chance to rescue them. Some unconvincing effects spoil the movie that was not exciting to begin with. If it wasn't for that Lalo Schifrin score, they'd find themselves in even deeper water. Okay for kids. Also known as AN UNDERWATER ODYSSEY, THE NEPTUNE DISASTER.
