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. ==See also==
