Storm Over Tibet is a 1952 American adventure film directed by Andrew Marton and starring Rex Reason and Diana Douglas.
Plot.
During World War II, David Simms pilots supplies between India and China over the Himalaya Mountains.
Production.
The film used footage filmed by Andrew Marton of the 1934 International Himalayan Expedition led by Norman Dyrenforth, whose son Harold Dyrenforth played a character based on his father. Much of the footage appeared in Marton's 1935 Swiss-German film "Demon of the Himalayas" with some sequences reused by Columbia in their 1937 film "Lost Horizon". Actor Rex Reason made his debut in the film telling an interviewer he was chosen for his role because the film needed an actor who could physically fit the shots of the previous actor who had died. Reason's 27 minutes of footage included climbing sequences filmed in an indoor studio using white painted corn flakes as snow.
Arthur Honegger reused some of his score from "Demon of the Himalayas".
