From the Oklahoman, an article on the silent film The Daughter of the Dawn, shot in 1920 in southwest Oklahoma using an American Indian cast, thought lost, but recently rediscovered (click on excerpt for full article):
Until Brian Hearn, film curator at the Oklahoma City Museum of Art, answered the phone one day about seven years ago. A private investigator in North Carolina said he had received a copy of a silver nitrate film as payment for an investigation, and thought the film was “The Daughter of Dawn.”
The investigator was interested in selling it. But since the museum hadn’t started collecting films, Hearn decided to contact the Oklahoma Historical Society. Through the actions of many people and organizations, the movie has been restored and rereleased with the first screening held in June at the deadCenter Film Festival in Oklahoma City.
