While watching this adventure film produced by Republic Pictures, I expected Edward Ludwig for directing, he who already gave us the awesome WAKE OF THE RED WITCH several years earlier, one of John Wayne's favorite, and a tremendous stuff too. Edward Ludwig was the adventure films specialist, but mostly for Paramount. So, I guess that in 1953, he was also under contract with Paramount and I presume that's the reason why Joseph Kane, the Republic prolific western maker, finally made this film. And for an excellent result. One of best Jo Kane's films. Please don't miss this one. It is really a great and underrated adventure movie providing amazing action and volcano in eruption scenes.
