Watch VoirFilms. Filmmakers (and canyon residents) Alexander and Anne Christine Von Wetter filmed this documentary for German Television in the early 1970s as a revealing close-up of an extraordinary period in America. The camera masters and 16mm negative were consequently lost to a devastating fire. Luckily, a lone VHS copy had been made, which spent the next 30 years on the studio shelf. The VHS was found heavily damaged, but a restoration team managed to salvage a fair grade of quality, which has since been remastered.
