"Actually THE CYCLOPS, filmed in 1955, was, like X THE UNKNOWN and RUN OF THE ARROW and several others, originally to be released by the then-struggling RKO. Many stills exist from these with RKO trademarks. But by 1957 RKO was on the ropes and many of the pics went to other distributors. Obviously some had already made RKO release negatives, if not prints. So the credits of the Monsters HD CYCLOPS are original. Whether that cut of the already quite short picture is too, is anybody's guess."
