MST3K 416: Fire Maidens of Outer Space

The most interesting thing about the movie in the Mystery Science Theater 3000 episode "Fire Maidens of Outer Space" ("Fire Maidens really grip the road!") might be the English accents a number of its astronaut characters have; otherwise, it might well be dismissed as just another in the string of "rocketing to another habitable world" movies the series featured. That dismissive conclusion might be easier to come by, though, because of the little story told in the episode's "host segments," one that ends up spilling into the movie itself...
