The working title of this film was Mask of the Himalayas. The following written prologue appears in the onscreen credits: "The outdoor scenes of this picture were filmed in the Karakoram region of the Himalayas at altitudes ranging up to 24,000 feet when these mountains were explored for the first time by the International Himalaya Expedition under the leadership of Prof. G. O. Dyrenforth of Switzerland. The ritual dances were photographed at the Buddhist Monastery of Lamayuru."
January 1951 news items indicate that director Andrew Marton photographed the Himalayan sequences featuring his wife, Jarmila Marton, during an expedition in 1936. Much of Marton's Himalayan footage was used in the 1936 Swiss production, Demon of the Himalayas, which was never released in the United States. Marton, who was borrowed from M-G-M, acquired the negative of the Swiss film and two additional reels of previously unused footage for Storm over Tibet. Jarmila Marton was the only cast member from the original 1936 footage available for the filming of Storm over Tibet. Portions of the 1951 footage were shot at General Service Studios in Hollywood.
According to the Hollywood Reporter review, Harald Dyrenforth enacted the role originally performed by his father, Norman Dyrenforth, who led the 1936 expedition. A January 1951 Variety news item reveals that the original musical score for Demon of the Himalayas by Arthur Honegger was used for Storm over Tibet. In January 1951 a New York Times item indicated that Norman Corwin contributed to a screenplay, but the extent of his contribution to the final film, if any, has not been determined. An undated, but contemporary, news item in the production file on the film in the AMPAS Library announced that Dr. Douglas H. Schneider, head of Mass Communications for UNESCO would serve as technical advisor for the film, but his contribution to the completed picture has not been confirmed. The same item announced that Philip Friend would play the role of a scientist, but his appearance in the finished film has not been confirmed. Although the character of "David Simms" appears to be the sole survivor of the avalanche at the story's end, the film does not actually show the other members of the expedition meeting their deaths.
