For some reason, I confused this movie with
Devil Girl from Mars. They showed this a couple of weeks ago on TCM and, while I was watching it, was wondering "Where's the woman in the tights and the giant refrigerator robot?". Then, it dawned on me, two different movies. I couldn't remember the title of the robot movie until I looked up Hazel Court. Both movies were shown on our local horror movie show about a week apart, maybe that's what caused the confusion.
