Vintage Bava in which Karloff introduces three adaptations from famous tales of the supernatural (and also stars in the last): The Drop of Water by Chekhov, The Telephone by Howard Snyder, and The Wurdalak by Tolstoy. Pictorially it's amazing, and even the script and dubbing are way above average. If only Amicus, who subsequently cornered the horror omnibus market, had taken heed they might have got some ideas as to what can be done with the format.
