Using the non-de-plume of Jonathan Rix, his grandfather's name, Dennis O'Keefe hied himself over to England and sold this story (with screenplay by John C. Higgins) and ended up as the star and (credited) director of this film that was merely a slight---primarily geography and accents---remake of at least a half-dozen American B-westerns with the plot gimmick revolving around a heroine's scientist father being kidnapped and forced to counterfeit something---diamonds, in this instance---for a gang of crooks. One of the readily available horses-and-sagebrush versions is 1941's "Dude Cowboy" from RKO with Tim Holt, Marjorie Reynolds and Byron Foulger essaying the roles taken here by O'Keefe, Margaret Sheridan and Paul Harmuth. Give "Dude" the edge over "Diamond" on the strength of Ray Whitley's songs.
