Vulnavia a perfect Stepford Wife
I suddenly made a mental connection. The character Vulnavia somehow foreshadowed the Stepford Wife concept. In discussions on the sequel concepts it was revealed that Vulnavia was originally going to be revealed as another one of Phibes' mechanical constructs, only vastly more complex and sophisticated, something like the artificial person of the Alien and Aliens sci-fi horror flicks.
I think a feminist would quickly scoff at the Vulnavia character. Here's a man's perfect companion: a beautiful young woman willing to do anything her man asks, without hesitation, without complaint, without question, and do it competently without delay. Plus she doesn't say anything, just obey. But when her man needs her for female companionship and romantic dancing, she's there, all dressed up and prettied, ready to entertain him.
I don't think anyone caught on to this feminist satire of a pre-Stepford Wife character of a man's perfect woman. The satire was this: A man's perfect woman is actually LESS than a woman.
