Hunter of the Unknown was one of dozens of European-based spy pictures made available in America on the heels of the James Bond craze. The Sean Connery clone this time out is a personable actor by the name of George Ardisson. His mission is to locate an international hit man before a peace-threatening political assassination can be carried out. As indicated by the title, no one knows who the assassin is--or whether it's a he or she. This means that even toothsome leading lady Evi Marandi isn't above suspicion. ~ Hal Erickson, Rovi
