In July 1949, RKO Pictures purchased the story written by Roy Hamilton. The film was originally set in
New England and was titled
The Man He Found. The term "the whip hand" is a
horse racing metaphor for having the advantage or upper hand. In the original draft of the film, the villains were escaped German Nazis involved in a plot to hide
Adolf Hitler, portrayed by
Bobby Watson. However, when studio chief
Howard Hughes viewed the completed film in November 1950, he ordered portions of the film reshot because the communists had replaced the Nazis as the world's greatest villains. Location shooting took place at
Big Bear Lake as well as at the RKO ranch in
Encino. The film lost an estimated $225,000. ==Reception==
