The working titles of this picture were Rangers of the North and The Glacier Story. Although the film was originally presented in 3-D, the viewed print was in standard format. The film opens with the following written statement: "The cooperation of the U.S. Department of the Interior, National Park Service, and Glacier National Park is gratefully acknowledged." Location shooting took place at Glacier National Park in Montana, according to reviews. According to a January 1952 Hollywood Reporter news item, RKO purchased a story by Stanley Jones entitled "Glacier National Park" and assigned Irwin Allen to produce it. As Jones's story reportedly was about "an Indian prospector," it has not been determined whether it was related to Dangerous Mission. A Hollywood Reporter news item lists William Janssen, Buck Russell and Robert Milton in the cast of Dangerous Mission, but their appearance in the final film has not been confirmed. Philip Ahn also is listed, but he did not appear in the film. RKO borrowed Victor Mature from Twentieth Century-Fox for the production.
