A ferryman who was wrongly hanged for murder is now a ghost, and he´s more than a little perturbed. He wants revenge, and he´s inflicting strange, violent deaths on the townsfolk responsible for this execution. The ghost (Charles Middleton, best-known for playing Ming the Merciless in the Flash Gordon series) is all the scarier for his simplicity: a grim shape that gradually manifests itself, blending into the shadows and the night. Blake Edwards, in a rare acting appearance before he became a famous director, is Christian Sanders, Jr., next on the ghost´s list of victims, and Rosemary La Planche is his lover who´s willing to sacrifice herself to save his life. Robert Barrat is the community leader who fights the villagers´ superstitions. Steeped in gothic atmosphere, Strangler Of The Swamp recreated director Frank Wisbar´s extremely stylish classic fantasy film, Fahrmann Maria, made in Germany before Wisbar came to Hollywood and directed such movies as the Devil Bat´s Daughter. Wisbar´s inventive use of lighting, camera and sets makes Strangler a stand-out.
