Wow ! Believe it or not Burgomaster this is a film that I have been thinking about for years, but just couldn't place the title with the film. Your discription of the movie was perfect and just as I remember watching it in the 70's. I remember liking this film alot along with many others like THE FLESH EATERS, KONGA, GIANT FROM THE UNKNOWN, THE CRAWLING EYE, PANIC IN THE YEAR ZERO. For many years now I have seen the color DVD cover art for THE ASTOUNDING SHE MONSTER (1958) and never imagined it was a film that I've been trying to think of the title for years. Been wanting to see THE ASTOUNDING SHE MONSTER also without knowing that it was a film that I was looking. The film idea reminds me a little bit of QUEEN OF BLOOD (1966). Looking forward to viewing THE ASTOUNDING SHE MONSTER again someday.
Thanks Burgomaster.
