Preserving old movies
Fading Shadows
According to the American Film Institute, about half of all feature films produced before the 1950s is gone -- either lost, destroyed or deteriorated beyond use because of the highly-flammable nitrate film stock on which motion pictures were photographed and printed. Poorly-preserved color film stock has also faded. The survival rate of silent films is even worse, with 80-90% gone.
