Any deleted footage?
As a small child, I saw this on TV under the title "Island of Living Horror". I distinctly remember seeing footage of native children playing among oversized plants. One of them stepped into a plant that closed up around him like a venus flytrap, although I don't think it was supposed to be eating him, I think it just snapped up and covered him and they were playing hide & seek.
The DVD release of this film under the correct title, "Brides of Blood", doesn't have anything like this in it. Am I remembering some other film?
