Ramona released April 5, 1916
There have been several versions of Ramona in sound and silent versions. On April 5, 1916, a silent movie version was released starring Adda Gleason and Monroe Salisbury. It was 14 reels, a length which was unusual at that time. In fact, one reviewer mistakenly wrote that it was directed by D.W. Griffith, because The Birth of a Nation had been a similar length.
The movie was filmed in multiple areas. "Locations . . . have been selected at San Diego, Santa Paula, Santa Barbara, San Clemente Island, in the San Fernando Valley, and at San Francisco . . . On San Clemente Island, unusual pictures were made in which the ten thousand goats grazing on the rocky island took part." – Moving Picture News, October 9, 1915
Good news – this movie does exist at the Library of Congress.
