Art, too, is dangerous: two vampires, brother and sister, 'mesmerize' a young bride during the playing of a passionately romantic piano piece. And just as The Brides of Dracula nuanced the traditionally Manichean distinction between the living and the undead, so, here, the newly vampired of this sub-species can brace daylight for short periods, if it's an overcast sky. For all that, the film doesn't escape the pitfall of its theme. Far from raising immorality to the level of vampire horror, it reduces vampirism to immorality, which, for censorship reasons is, in its turn, reduced to rather sedate orgies. Sharp, no mean stylist, doesn't really believe in the supernatural. The cold wind tearing autumn leaves remains simply a cold wind tearing autumn leaves.
