Foreign Intrigue was one of the first major Hollywood films to be based on a popular TV series. Robert Mitchum stars as an American press agent who travels the length and breadth of Europe to learn the past of a recently deceased multimillionaire. After stopovers at the Riviera, Stockholm and Vienna, Mitchum learns that the dead man accumulated his wealth by blackmailing war criminals and Nazi collaborators--all of whom would be happy if Mitchum would disappear, or die, or both. In her first English-language film, Ingrid Thulin (billed as Tulean) plays one of the hero's several amours, as does the toothsome Genevieve Page, likewise making her first American film appearance. After a brief but profitable theatrical release, Foreign Intrigue returned to its roots when producer Sheldon Reynolds sold the picture to TV in 1958.
