If the ambition is to provide two hours of instantly forgettable, popcorn-munching escapism, it succeeds.

After playing with our expectations, this turns out to be a very different sort of film.

There are moments in this movie where the great movie it could've been peek out... They're fleeting, here, but they're worth savoring, and they happen often enough to make it worth your while.

One of the worst ways to make a cult movie is to set out to make a cult movie.

This film begins with a biochemist named "Dr. Dan Scott" (Jack Kelly) feverishly working on a research project involving human adaptation to disease by using fruit flies. Although his experiments on various animals were a tremendous success he now wants to try it on an injured or sick human being. But complicating matters is the fact that his main sponsor, "Dr. Richard Bach" (Albert Dekker) vehemently disagrees with human research without further testing. He changes his mind, however, when he meets a patient named "Kyra Zelas" (Mari Blanchard) who is suffering from terminal tuberculosis and doesn't have long to live. To everyone's surprise, upon injecting the experimental formula, she fully recovers within hours. Unfortunately, both doctors soon learn that the serum has side effects they never reckoned with. Now rather than reveal any more I will just say that this was a fairly decent horror film which definitely benefited from the complete disdain Kyra had for any and all social norms that most people have to observe. She was totally without conscience and human feeling. Even so this movie was clearly a grade-B film and for that reason I have rated it accordingly. Average.

They created an inhuman being who destroyed everything she touched! The woman they could not kill! This film was written, produced and directed by Kurt Neumann, best known for "The Fly" (one of his next features). He was also allegedly considered for the director's chair on "The Bride of Frankenstein", though I must say I am glad James Whale got the job.Worth noting is that the source material came from Milwaukee native Stanley Grauman Weinbaum, who sadly died at age 33 and never saw his work brought to the screen. Weinbaum, though not well known today, was influential in the 1930s and H. P. Lovecraft praised his work.While all of the film is quite good, the best part is probably the awesome sequence of a car driving off a cliff... no dummies were killed in the making of the movie!

Two scientists (Albert Dekker and Jack Kelly) treat a young female patient's medical trauma with an injection that has a profound effect: the woman's black hair becomes luminously blonde, she gains an irresistible sexual magnetism, but she also becomes an impulsive thief and killer possessed with the instinct to get whatever she desires at any cost. Mari Blanchard is ideal in her role as the gorgeous femme fatale, who has also gained an immunity and cannot be stopped even by her own doctors who've created her. Albert Dekker (popular to fans for his title role of DR. CYCLOPS) spews a lot of hokey dialogue in his remarkably self-assured manner. The younger Jack Kelly is his assistant hovering on falling under Blanchard's spell. Another fun 1950s 'B' . **1/2 out of ****

I too recall this picture when I saw it in a movie theater in Ashtabula, Ohio in the 50's. What I found fascinating about it was the Dr. who was in love with this patient and how difficult it was for him to finally make the decision to give her a shot of the anti-serum to stop the violence. I remember how she willed herself to change and become a blonde when she was in the changing room, how the Dr. stole some hair from her hair brush so he could have it analyzed and when she is given the final anti-serum and reverts back to the sweet brunette he loved. Even as a 8 year old,it touched me and made it quite memorable, even in these times. Would love to see it re-done as well. Also, does anyone know if there is any way to get a VHS of this picture?
