 Nordisk Film had an alternative ending shot for the Russian market, since  Russian culture prefers unhappy endings over the western happy endings. In  the alternative version, Dr. Kammacher dies of an heart attack right after he  hears the news that his new love has died. Unfortunately for Nordisk Film,  the writer of the novel, Gerhart Hauptmann had made it very clear in his  contract that no changes to his story could be made. So Nordisk Film released  the alternative version only in Siberia, hoping Hauptmann wouldnt find out.
