Maneater of Hydra is a SpanishGerman coproduction released in 1967 directed by American expatriate Mel Welles. The alternate titles include La isla de la muerte, Island of the Doomed and The Blood Suckers UK title. The horror film is set on a remote island off the shore of an unidentified European country, in which the central character is a mad scientist Cameron Mitchell who creates hybrid trees that feed on human blood.
According to one reviewer, This SpanishGerman coproduction .. is pretty bloody for its time especially the finale but, unfortunately, the print used for the DVD from Shout Factory as part of their Elvira Movie Macabre series is a terribly soft fullframe speckled mess thats full of dropouts, emulsion scratches and jitter. Its also obvious that its a TV print although it appears to be uncut, as every ten minutes the film fades to black. If youve never seen this film before, its a pretty decent mysteryhorror film with some fluid camerawork, atmosphere and a few good scares.DVD Verdict reported Maneater of Hydra is ...a badly acted and dubbed Eurohorror that gives us carnivorous trees feasting on unsuspecting tourists. Unfortunately, these tourists are so whiny and clueless that they come off as idiots, so you end up rooting for the trees. ........
