David Dodge's novel is brought to the screen with Ford excellent as protagonist Al Colby. The script however, plays fast and loose with the novel, changing the locale from Peru to Mexico and now the search is on for Aztec artifacts instead of Incan. All things considered, this is a tightly directed and well acted tale. It has not been available for viewing as it seems to be tied up in litigation along with "Island in the Sky"(1953) and "The High and the Mighty"(1954)as the Wayne Family battles Warner Brothers and we are the losers.
