Victor Mature stars in this European-based crime thriller. Mature is an FBI agent on the trail of a drug smuggling operation, following his quarry all over the Continent (with accompanying pretty pictures of Portugal, Spain, France etc.) The criminal mastermind (Trevor Howard) is something of a lunatic, who has already strangled Mature's sister to death just for the hell of it. Anita Ekberg plays Howard's luscious courier; as usual, her "acting" consists to breathing heavily in a low-cut dress. The title Pickup Alley was the invention of Columbia's New York office: The film's original British title was Interpol.
