Oscar Shorts Finder

Facing Your Danger is a 1946 American short film. The cameraman was amateur filmmaker Edwin E. Olsen. Using a Cine-Kodak and 16mm Kodachrome film, Olsen shot the film in 1942 on a Grand Canyon river trip conducted by Norman Nevills. Another amateur cameraman on the trip was Otis R. Marston. When Olsen ran out of film, Marston, who had brought 6,000 feet of Kodachrome magazines, provided Olsen with what he needed. Olsen edited the film and sold it to Warner Brothers in 1946.
