Director George Pal is noted as a special effects maestro, both in films for children that feature his "puppetoons" and in sci-fi spectacles like the War of the Worlds. So it is no surprise that this sci-fi yarn about the fabled sunken continent of Atlantis should excel in the special effects department. Otherwise, the story is a clichéd tale about Demetrios (Anthony Hall) a Greek fisherman who is tempted into going to Atlantis by Antillia (Joyce Taylor), a princess of that doomed land. Demetrios is soon trapped into slavery, a situation which leads him to hobnob with the oppressed masses and plan a strategy to get them out of there before the rumblings of imminent submersion send the whole kit and caboodle into the briny deep.
