Unnatural (1952)

Erich Von Stroheim stars as the bizarre scientist in this off the wall science fiction film. This mad scientist artificially inseminates a prostitute with the sperm of a murderer, creating a beautiful but artificial and dangerous woman, (played by Hildegarde Neff). With neither a soul nor morals, consequently this "unnatural" woman induces disaster amongst all those around her. Taking a bit of the worst qualities of both "parents", she entices men into her control and then goes on to murder them. Jealous Von Stroheim ends up demolishing his own creation when he sees Neff taking a heavy liking toward a man, (played by Karl Bohm). Based on the book, "Alraune" by H.H. Ewers.
