There was a glut of undersea action film in 1989. The only one that really had any credibility was James Cameron’s The Abyss. Although it was not a box office success, the film gained a following over time and was substantially improved by the release of the special edition in 1993. Leviathan conversely, is one of the forgotten titles from that aquatic sub-genre. The plot follows a team of undersea miners that find a sunken Russian vessel. A case of recovered vodka turns out to be a genetic mutagen, resulting in crew members mutating into an aquatic human hybrid. It’s all conspicuously derivative and the embodiment of the term formulaic. Yet despite these flaws it does have a few virtues that merit a viewing, if you’re feeling undemanding.
