Lon Chaney's character was originally called Rattavich, but the name was softened to Farralone to appease censors, who felt that the original name was too unsubtle as to the origins of the group.
Second of four films Lon Chaney made for Goldwyn Pictures.
The original ending to the film picked up after the bomb explodes at the meeting headquarters. Forrest and Lillith are living in a cabin in the woods, and believe that they are safe thanks to Farralone. Rushing back to the cabin to warn Lillith, he sees Morgridge, who tells him that they have nothing to fear - Farralone's sacrifice has taught him that love is the solution, not destruction. This ending was cut on the request of Samuel Goldwyn, who felt that it was too contrived and that the lovers reading about it in the newspaper was a much more satisfying ending.
