This LOST film was Clara Kimball Young's first feature, and her last film for Vitagraph, where she had made all of her short films. It was a sensational success and launched her as the most popular star that year. Its Russian setting was drawn upon by Young for many more of her features. Two short clips of the film exists in Warner Brother's 1931 Vitaphone short "The Movie Album," and have been mounted on Internet Archive and Google Video.
