Richard Harrison, as Perseus, walks amongst men who were turned into stone in PERSEUS THE INVINCIBLE (aka Medusa vs the Son of Hercules)
The Spanish title for this is EL VALLE DE LOS HOMBRES DE PIEDRA, which translates as THE VALLEY OF THE MEN OF STONE. Nothing about Perseus or the Medusa being responsible for turning men into stone. The Spanish version is also different to the the Italian one during many instances. Made before CLASH OF THE TITANS which was obviously inspired by this excellent PEPLUM.
