Koz- Actually it was made in 1953. I know because I checked a movie reference, and also because I was a little kid when it first appeared- scaring the hell out of me. I remembered it as the "Man with White Eyes" because that's what happened when he turned on the x-rays looking at people. But they may have been black, as you remembered them too. I was so scared at the time I could barely watch any of it (I was I think about 5 years old.)I have never seen it since then, but Ray Milland was the star and it has since become a Four Star Cult Movie Classic of Roger Corman's. I saw it at a U.S. Air Force SAC/MAC base near Sacramento, Ca. back when they still had B-29 bombers- I was a military dependent. (It was a B-29 that dropped the bomb on Japan. And that spun off all the interest in sci-fi movies about nuclear mutations, X-Rays and the very first Alien UFO sightings)
