“Young pawns thrust into pulsating cages of horror in a sadistic experiment!” The Wikipedia article on this 1958 or 1960 oddity (the article can’t agree with itself) suggests that it is one of those rare examples of a mad science movie with a female antagonist. This poster is reblogged from 15 November 2013 post at Infernal Wonders. I originally found it at the tumblr Monsters Forever.
Yeah, I’ve seen it, and it does have a female antagonists. But it’s just awful, and in a boring way. Plus it doesn’t deliver the goods; no one comes anywhere near becoming a teenage zombie. Trust me, it’s no “Dr Tongue’s House of Flying Stewardesses.”
She looks somewhat like Lubna from RanXerox
Given the dates, Lubna resembles the girl in this poster.
