You owe it to yourself to sit through ONE viewing of that movie in your life time. Seriously. It's wack, and dumb, but fun, and interesting, and some pretty deep philosophy buried under the crazy 70s surface. I'm NOT saying it is a good film, just that you should experience that costume and all the crazy around it. Then, you will also notice all the social influences it had here and there and everywhere. Hidden in plain view.
#5 on that list is wrong. Altaira did NOT wear live budgies on her ears! I've watched Forbidden Planet dozens of time and never ONCE did I see her with large hoop earrings sporting live birds.
