An early adventure movie from Fritz Lang featuring Kay Hoog, a dashing adventurer who bears more than a passing resemblance to Indiana Jones, and who was originally to be the hero of a series of four movies, only two of which were ever made. Hoog, as played by Carl de Vogt, is something of a solemn character lacking in dynamism, but he's locked in a pleasingly involving battle with the sinister Die Spinnen organisation in his search for a hoard of Inca gold. The film takes itself a little too seriously on occasion for what is essentially a Boys Own story, but Lang keeps it clipping along at a fast enough pace to keep his audience entertained.
