The 22 July 1916 Motion Picture News announced that Henry McRae was currently filming Behind the Lines at the Universal City studios. Edwin N.

       According to the 2 September 1916 Moving Picture World, "Mr. McRae took his company to Lower California, where the military features were pictured in authentic locations." Lower California is more commonly known as the state of Baja California, Mexico. (Another item in the same issue more directly stated that McRae had taken "his large company to Mexico for authentic locations.") The first item also gave 18 September 1916 as an opening date for the film, and noted that the scenario was adapted from Mary Rider's "published novel," although no such book could be found.

McFadden loaned it to [Ray] Hanford for use in the film play."
       According to the Library of Congress American Silent Feature Film Survival Database, a fragment of this film is extant. ...
